Is Kratom Being Spiked With Other Drugs?

By Pat Anson, PNN Editor

It’s no secret that illicit fentanyl has become a scourge on the black market. The potent synthetic opioid – about 100 times stronger than morphine --  is now involved in over half of U.S. overdoses. Fentanyl is being found in a wide variety of street drugs, including heroin, meth, cocaine and marijuana, and it is increasingly used in the manufacture of counterfeit painkillers and other fake medications.  

“As traffickers have expanded into the sale of fentanyl-containing counterfeit pills, the scope of users who were exposed to fentanyl increased significantly; the prescription pain reliever misuser population is almost ten times that of the heroin user population,” a recent DEA report warns. “The presence of fentanyl-containing counterfeit pills in an area is increasingly associated with spikes in overdose deaths.”

Although there is no hard evidence that drug dealers are mixing fentanyl with kratom to boost its potency, some in the kratom community think it is inevitable that someone will try. There have already been cases of kratom products being adulterated with hydrocodone and other opioids.

“I don’t know that there’s been a case of fentanyl in kratom, but since that’s what they are finding in everything else and that is the most dangerous drug out there now, it stands to reason that someone who would spike kratom with hydrocodone would now spike it with fentanyl either wittingly or unwittingly,” said Jane Babin, PhD, a molecular biologist and consultant to the American Kratom Association (AKA), an advocacy group for kratom vendors and consumers.

Like other dietary supplements, kratom products are essentially unregulated and there are little or no quality controls.

In an effort to change that, this week the AKA officially launched a good manufacturing practice (GMP) program, which will require producers of kratom products to meet strict manufacturing standards verified by a third-party auditor if they want to be certified by the AKA.  

"The AKA GMP Standards Program will help reassure the public and demonstrate to the FDA, DEA, lawmakers, and others that the kratom industry is acting responsibly," AKA president Dave Herman said in a statement. 

"The AKA GMP Standards Program will also protect kratom consumers from unscrupulous vendors who produce kratom products using sloppy manufacturing procedures that allow for contamination, and equally important the standards program will exclude vendors who deliberately adulterate kratom products to boost their effect by adding dangerous and sometimes deadly substances like fentanyl or morphine." 

In recent years, millions of Americans have discovered kratom, which has been used in southeast Asia for centuries as a natural stimulant and pain reliever. Kratom is widely available online and in smoke shops, but the quality of what’s being sold and where it comes from is often unknown – even by the people selling it.

“The stuff that’s sold as kratom in the United States cannot be reliably proven to be kratom,” Edward Boyer, MD, a Professor of Emergency Medicine at Harvard Medical School, recently told PNN.  “There is evidence to suggest that some of the kratom sold in the United States is adulterated to make it more potent, to make it more powerful.”

Boyer says some kratom products have been found to contain artificially high levels of 7-hydroxymitragynine, one of the naturally occurring alkaloids that make kratom act on opioid receptors in the brain. Manufacturers may also be lacing kratom with opioids and other drugs.

“One theory is that some unscrupulous vendors may be spiking kratom with something more potent to drive business. It may be even more prevalent than we know, which could account for some of the reports on Reddit and Blue Light (online message boards) that say kratom is addictive and it does lead to euphoria,” Babin said in an email.

A handful of states have already banned kratom and there is speculation that the DEA will soon try again to schedule it as a controlled substance, something the agency backed away from in 2016 after a public outcry. The FDA has recently mounted a public relations campaign against kratom, what the AKA calls a “shadow ban” that has led to kratom shortages.

Could the AKA’s effort to improve the quality of kratom products backfire by giving ammunition to federal regulators who want a nationwide ban?

“That kratom may be adulterated is not a reason to ban it.  There are reports all the time of dietary supplements, even ones sold by reputable companies like GNC and Vitamin Shoppe, are adulterated with prescription drugs, banned substances and who knows what else,” says Babin.

“The other thing to consider is that if kratom is banned, demand may lead to a black market.  It will likely be smuggled in and/or products not containing kratom will be sold as kratom and those may be spiked with other substances, including fentanyl.”

Is FDA ‘Shadow Ban’ Causing Kratom Shortages?

By Pat Anson, PNN Editor

The American Kratom Association (AKA), an advocacy group for kratom vendors and consumers, came out with an alarming bulletin this week.

“BREAKING: FDA Commissioner Scott Gottlieb is shutting down kratom supplies shipments to the United States. The AKA is running out of time and resources to make sure we can secure the supply chain for you to purchase kratom,” read the post on the AKA’s Facebook page.

The bulletin claimed the FDA was trying to “criminalize kratom users” and then launched into a fundraising appeal asking supporters to “dig deep and send a contribution right now” to the AKA to support its lobbying efforts.

At best, the AKA’s bulletin was premature. At worst, it was misleading. Gottlieb is certainly no friend of kratom, but he’s not issued orders shutting down imports of kratom, an herbal supplement long used as a stimulant and pain reliever in southeast Asia.

The FDA declared an “import alert” for kratom in 2012 and again in 2014 – long before Gottlieb became commissioner – authorizing the seizure of dietary supplements containing kratom. Several large shipments were confiscated as a result of the alert, but clandestine imports of kratom into the U.S. continued largely unchecked.

Kratom has since become widely available online and in many smoke shops, and millions of Americans have discovered kratom can be used to self-treat their chronic pain, anxiety, depression and addiction.

AKA president Dave Herman told PNN the bulletin was based largely on anecdotal reports from a handful of vendors who had kratom shipments confiscated in recent months.  

“I’m sure some of them don’t want to talk about it, but I’ve talked to at least four or five that said their stuff has been grabbed,” Herman said. “I know of one vendor that had a hundred tons literally confiscated.

“We feel from day one that commissioner Gottlieb has been running a shadow ban. It’s clearly an attempt to ban and they’re using any and all portals to do that. But can I hand you a piece of paper (from FDA) that says, ‘We’re doing it?’ No.”

Herman said some kratom vendors are down to a few weeks supply.  

“There’s a lot of fear about what’s going on out there,” he said.

Kratom Demonized

Inflammatory rhetoric and scare tactics have become increasingly common in the escalating debate over kratom.

Gottlieb publicly calls kratom an “opioid” – even though its active ingredients are alkaloids -- while claiming there is “no evidence to indicate that kratom is safe or effective for any medical use.” Last year, the FDA claimed dozens of fatal overdoses were associated with kratom, while admitting nearly all of the deaths involved other drugs and “could not be fully assessed.”

Several kratom products were recalled earlier this year during an FDA and CDC investigation of a small salmonella outbreak associated with the herb. Although the source of the outbreak was never identified and only about 200 people were sickened, Gottlieb said “anyone consuming kratom may be placing themselves at a significant risk of being exposed to salmonella.”

More recently, Ohio health officials have claimed kratom produces a “heroin-like high” and was being used intravenously by drug addicts – a notion that most kratom users found preposterous.

“Who the hell is injecting kratom? These people are out of their minds,” one reader told us.

The FDA did not directly respond to a request for comment on the AKA’s bulletin, only saying that “certain kratom products and importers” were targeted in its 2012 import alert. But Herman says it is clear to him what’s happening in 2018. “It’s a full demonization. I don’t think there is any doubt about that,” he said.

Herman believes federal health officials may be trying to avoid scheduling kratom as a controlled substance, something the DEA tried and failed to do in 2016 after a public outcry.  Scheduling kratom would require a public comment period and likely get Congress involved, which the FDA can avoid with a “shadow ban.”

“It’s a concerted effort. There is a (kratom) shortage out there. The shortage didn’t exist previously,” Herman said. “The range I’ve heard of any (vendor) inventory is the highest is 6 months and the lowest is two weeks. There’s definitely a movement there and its harder and harder to get the product into the country.”

When asked if the AKA bulletin could incite fear and lead to hoarding and price increases, Herman was circumspect.

“Some people will stock up. Some won’t,” he said. “How people react, I can’t anticipate. I don’t know the answer to that. I do know that’s there’s a shortage of product. And I think prices have already risen, best as I can tell.”   

Kratom Missing From DEA Report on Drug Threats

By Pat Anson, PNN Editor

The Drug Enforcement Administration has released the 2018 National Drug Threat Assessment, the agency’s annual report on drug trafficking and drug abuse in the United States.

Over 150 pages long, the annual report paints a grim picture of a nation overwhelmed by a tsunami of illicit fentanyl, heroin, prescription opioids, meth, marijuana, cocaine and other drugs that the DEA says are having “a devastating effect on our country.”

Conspicuously absent from the report is kratom, the herbal supplement that the FDA blames for dozens of fatal overdoses and the DEA once tried to list as a dangerous controlled substance — the same substance that Ohio health officials call a “psychoactive plant” that produces a “heroin-like high.” Ohio will soon join five other states in banning the sale and possession of kratom.

But there’s not a word about kratom in the National Drug Threat Assessment. There never has been.

“It is not surprising.  Kratom is not the ‘dangerous opioid’ that the FDA has made it out to be,” says Jane Babin, PhD, a molecular biologist and consultant to the American Kratom Association, an organization of kratom vendors and consumers.  “It does not kill throngs of people like heroin and synthetic opioids. Everything we know about kratom is that people use it to avoid much more dangerous prescription and illicit opioids.”

Kratom comes from the leaves of a tree that grows in southeast Asia, where it has been used for centuries as a natural pain reliever and stimulant. In recent years, millions of Americans have discovered kratom and use it to self-treat their chronic pain, addiction, anxiety and depression.

As kratom has become more popular, the public health campaign against it has intensified. A small salmonella outbreak earlier this year in kratom products led to several recalls and stark warnings that “anyone consuming kratom may be placing themselves at a significant risk.”

Nearly 200 people were sickened in the outbreak, but no one died and the CDC never identified the source of the salmonella.

FDA commission Scott Gottlieb, MD, has taken to calling kratom an “opioid” (its active ingredients are alkaloids) and regularly tweets that consumers “should be aware of the mounting risks” of using the herb.

Yet there’s been no mention of kratom in the DEA’s annual assessment of drug risks in the United States.    

““Every year that goes by in which alleged ‘kratom-associated deaths’ don’t even merit a mention by DEA in this report further drives home the relative safety of kratom,” says Babin. “The only thing peculiar is that FDA refuses to acknowledge these facts.”

Do Drug Addicts Really Shoot Kratom?

By Pat Anson, PNN Editor

Our story last week about drug addicts in Ohio allegedly shooting kratom to get a “heroin-like high” angered many people who use the herbal supplement to treat chronic pain and other medical conditions.

“Who the hell is injecting kratom? These people are out of their minds,” wrote one reader.

“No one and I mean no one has ever injected kratom. Kratom is a wonderous, natural plant with many positive effects,” said Erik.

“It’s pathetic that lies like this are being spread about a natural leaf that helps with pain,” wrote Jennifer Greenwood. “Nobody buys kratom from heroin dealers.”

But that’s exactly what the Ohio Substance Abuse Monitoring Network (OSAM) reported earlier this year in its statewide assessment of drug abuse trends. OSAM called a kratom “a psychoactive plant” and claimed drug users in northeast Ohio were buying kratom from heroin dealers and then injecting it.

“Participants reported that the most common route of administration for kratom is intravenous injection (aka “shooting”). Participants in the Akron-Canton region estimated that out of 10 kratom users, seven would shoot the drug and three would orally consume the drug (including drinking it as a tea),” OSAM said.

The OSAM report was cited by the Ohio Board of Pharmacy when it voted last week to classify kratom as a Schedule I controlled substance, alongside heroin, LSD and other dangerous drugs.

The board said kratom can cause hallucinations, psychosis, seizures, weight loss and insomnia, and cited six deaths in Ohio in which kratom was “the primary cause of death.”

The FDA and DEA have made similar claims about the health risks of kratom, but OSAM appears to be the first public agency to allege that kratom is taken intravenously. Repeated calls to OSAM for further information were not returned.    

Kratom comes from the leaves of a tree that grows in southeast Asia, where it has been used for centuries as a pain reliever and stimulant. In recent years, millions of Americans have discovered kratom and started using it as a treatment for pain, addiction, anxiety and depression.

“I don’t think most kratom users are injecting it.  Most users that I’ve ever talked to either mix it with a beverage, ‘toss and swish’, or take capsules,” says Jane Babin, PhD, a molecular biologist and consultant to the American Kratom Association, an organization of kratom vendors and consumers.

While skeptical that anyone would inject kratom, Babin says some addicts are desperate enough to try anything. She thinks the kratom sold by drug dealers in Ohio could be adulterated heroin.

“They describe kratom as a brown substance that resembles heroin.  So I can’t help wondering if what they were using was heroin or at least something other than kratom,” Babin wrote in an email to PNN.

“I can’t imagine that they would be mixing powdered leaf kratom with liquid, heating it and injecting it.  There’s too much insoluble plant matrix/cellulose.  If they did, I would expect problems unless they could filter it… which isn’t likely.  Injecting an ethanol extract directly would likely cause tissue damage, and I have to wonder how sterile any of it is.”

bigstock-Mitragynina-Speciosa-Or-Kratom-229830793.jpg

But there is a case in the medical literature of a 29-year old Rhode Island man doing just that. He started using kratom to treat his opioid addiction, but eventually developed a tolerance for it and needed more.

“He was initially drinking Kratom tea daily, then several times daily, until he found a way to inject it intravenously,” researchers reported last year in the Journal of Toxicology and Pharmacology.

“He began buying Kratom extract in alcohol. He let the alcohol evaporate in a spoon, and then dissolved the remaining resin in water to inject. Subsequently, he began cooking off the alcohol with heat. Finally, the patient said that he was impatient, and began injecting the extract directly. At the time of presentation, he was buying Kratom extract from multiple online vendors, and injecting 1 ml of extract six times daily.”

The man eventually checked himself into an emergency room and sought treatment for kratom addiction.

“This case is an important reminder of the chronic nature of opioid addiction, which has a high rate of relapse. As Kratom becomes more popular in patients seeking abstinence from opiates, including heroin, such intravenous use may also increase,” researchers warned.

Adulterated Kratom

One of the co-authors of that study believes there is another potential risk. Like other food and herbal supplements, kratom products are essentially unregulated and there are little or no quality controls.

“The stuff that’s sold as kratom in the United States cannot be reliably proven to be kratom,” says Edward Boyer, MD, a Professor of Emergency Medicine at Harvard Medical School.   

bigstock-Tablet-with-the-chemical-formu-82174202.jpg

“There is evidence to suggest that some of the kratom sold in the United States is adulterated to make it more potent, to make it more powerful.”

Boyer says some kratom supplements have been found to have artificially elevated levels of 7-hydroxymitragynine, one of the naturally occurring alkaloids that make kratom act on opioid receptors in the brain. He suspects opioid drugs are also being used to boost kratom’s potency.

“The fact that a lot of kratom is adulterated is not surprising,” says Jane Babin.  “I suspect it is more prevalent in the stuff that’s being sold at smoke shops and gas stations.  This is a red herring when it comes to kratom, in the same way that Salmonella contamination is.  Both are ‘problems’ with simple solutions through regulation and oversight of kratom identity and purity.”

Instead of banning kratom, Babin says it should be regulated with a standards and certification program that would help keep adulterated products off the market.

Kratom is already banned in Alabama, Arkansas, Indiana, Vermont, Wisconsin and the District of Columbia. And there is speculation that the DEA may try again to classify kratom as a federal Schedule I controlled substance, which would make sales and possession of the plant illegal nationwide. The DEA withdrew a plan to ban kratom in 2016 after a public outcry.

Last week’s vote by the Ohio pharmacy board starts a months-long process of drafting new regulations for kratom, so a ban isn’t in effect yet. Public comments will be accepted until October 18. 

“If Ohio does ban kratom (and I hope they don’t), I predict that the already epic opioid overdose problem in that state will get worse,” says Babin. “It would be a shame for Ohio to indirectly prove the value of kratom in combating the opioid crisis when, after it is banned, overdose deaths and suicides increase.”

Ohio Banning Sales of Kratom and CBD  

By Pat Anson, PNN Editor

At a time when many pain sufferers are turning to natural supplements to relieve their pain, the state of Ohio is moving to ban two of the most popular ones.

The Ohio Board of Pharmacy voted Monday to classify kratom as a Schedule I controlled substance alongside heroin, LSD and other dangerous drugs. The move came two months after the board issued an advisory warning that sales of CBD-infused products are illegal under Ohio’s new medical marijuana program.

The pharmacy board considers kratom – which come from the leaves of a tree that grows in southeast Asia – a “psychoactive plant” that can cause hallucinations, psychosis, seizures and death. State health officials have identified six recent deaths in Ohio in which kratom “was indicated as the primary cause of death.”

A recent report from the Ohio Substance Abuse Monitoring Network (OSAM) raised the demonization of kratom to a new level by comparing it to heroin — and falsely claiming it was common for people to inject kratom.

“Participants reported that the drug looks similar to brown powdered heroin, produces similar effects as heroin, and is primarily used by individuals subject to drug screening and by people addicted to heroin who use the drug to alleviate opiate withdrawal symptoms,” the OSAM report warns.

“Participants reported that the most common route of administration for kratom is intravenous injection (aka “shooting”). Participants in the Akron-Canton region estimated that out of 10 kratom users, seven would shoot the drug and three would orally consume the drug (including drinking it as a tea).”

osam kratom.png

Monday’s vote by the pharmacy board starts a months-long process of drafting new regulations for kratom. Public comments will be accepted until October 18.  Over 1,500 comments have already been received, most of them from kratom users asking the board to keep the supplement legal.

"The findings of the Ohio Board of Pharmacy… parrot the false propaganda of the U.S. Food and Drug Administration in their crusade to ban kratom," said Dave Herman, chair of the American Kratom Association, which represents kratom vendors and consumers. "The FDA has flooded state regulators, including the Ohio Board of Pharmacy with false claims and disinformation about the addiction profile and safety of this safe botanical plant.

“The nearly 5 million kratom consumers, and the tens of thousands of Ohio citizens, who safely consume kratom as a part of their health and well-being regimen should not have that freedom infringed upon by any regulation that is premised on bad science, inaccurate data provided by the FDA, and a deliberate attempt to manipulate the scheduling process by a federal agency.”

Kratom has been used for centuries as a pain reliever and stimulant, particularly in rural areas of Indonesia and Thailand.  In recent years, millions of Americans have discovered kratom and started buying it online or in “head shops” as a treatment for pain, addiction, anxiety and depression.

The Food and Drug Administration maintains that kratom is not approved for any medical use and insists on calling the plant an “opioid,” although its active ingredients are mitragynine and 7-hydroxymitragynine, two alkaloids that act on opioid receptors in the brain.

Kratom is already banned in Alabama, Arkansas, Indiana, Vermont, Wisconsin and the District of Columbia. There is speculation that the FDA and DEA may also seek to classify kratom as a Schedule I controlled substance, which would make sales and possession of the plant illegal nationwide. The DEA withdrew a plan to ban kratom in 2016 after a public outcry.

CBD Sales Banned

Ohio’s crackdown on CBD sales is not as restrictive as the ban on kratom. CBD infused products such as edibles, tinctures and oils usually contain little or no THC – the psychoactive ingredient in marijuana that makes people high. Many people use CBD to relieve pain and help them sleep.

Under state law, marijuana is defined as “all parts of a plant of the genus cannabis” and only state-licensed dispensaries can sell products made with CBD (cannabidiol). There will eventually be 56 dispensaries across the state, although none are expected to open until later this year.

Some retailers pulled CBD products from their shelves after the warning from the pharmacy board, but many have chosen to sell off their supplies first. One retailer in Dayton predicts the price of CBD products will soar once they are no longer widely available.

“The prices, if they’re going to skyrocket, are going to hurt customers’ pockets,” Rabi Ahmad told WHIO.com. “Senior citizens mostly buy the CBD. The young kids, they don’t buy CBD at all.”  

A spokesman for the pharmacy board said there are no state plans to enforce the ban on CBD sales, although local law enforcement agencies could. Also unclear is how the ban will affect online sales and shipments from out-of-state vendors.

“The public should have uninhibited access to hemp-derived products no matter what state you live in. We will continue to produce these products and support our retailers and customers through this moment of confusion,” Nic Balzer, CEO of QC Infusion, a Cincinnati-based manufacturer of CBD products, told Cincinnati.com.

Everything I Learned About Using Kratom for Pain

By Crystal Lindell, PNN Columnist

Here’s the thing about kratom. It works. It seriously works. If you are having a horrific pain flare and you put some under your tongue, your pain will be gone in less than three minutes. True story.

It also made me gain 27 pounds because it acts like an antidepressant in a lot of ways, and my body always gains weight when I’m on drugs like that.

And it’s pretty expensive — about $20 for 30 grams if you don’t get it in bulk, which is about six servings. For me each dose only lasts between two to five hours depending on how bad my pain is. You can get it in bulk, which I recommend, and then it’s $150 for 1 Kilo — so much cheaper per serving.

But even if you get it cheap, it’s really disgusting. I take it by shoving a spoonful under my tongue, saying a prayer, holding back the urge to vomit, and chugging Gatorade to get it down. It’s not the only way to take it, but it’s the only way that hits you in less than three minutes.

I’ve heard others put it in tea or smoothies, and of course there are capsules, but those take longer to kick in and don’t seem to work as well.

There’s also a lot of brands and strains and it can be hard to find the ones that works best for you.

bigstock-Mitragynina-Speciosa-Or-Kratom-229830793.jpg

Trainwreck Kratom by Earth Kratom is by far the best version I have found, and it literally relieves my pain as much as hydrocodone would on most days. It’s a mix of 11 different kratom strains and they seem to work better together.

But even with all the drawbacks, kratom has some serious advantages.

First and foremost, I have access to it. There’s no need for a prescription or a trip to the doctor — just a quick stop by the local smoke shop and I’m all stocked up. And it’s completely legal in most states, so there’s no need to worry about some of the issues that come with marijuana usage.

In addition to helping with pain, it also helps with depression and anxiety, which is great seeing as how most people in chronic pain have one or both.

It’s also the perfect way to get through a physical opioid withdrawal, as it will eliminate your symptoms in most cases. Yes, then you’ll have to go off kratom after that, but it’s much easier than the withdrawal that hydrocodone tends to bring with it.

One drawback is that most doctors don’t know much about it, so it can be hard to explain to them that you’re using it and they likely won’t be able to tell you how it will interact with other medications. There’s also been some bad press around it, including reports of deaths, so doctors may be wary about you using it at all. The FDA considers kratom to be an opioid and says it should not be used to treat any medical condition.

But if you’re dealing with serious chronic pain, and you’re sick of jumping through hoops to get an opioid prescription or your medication just isn’t cutting it, I would highly recommend you give kratom a try.

Just don’t try to take it with a carbonated beverage. The bubbles will lift it into your sinuses, and it feels like you’re being waterboarded with dirt. But other than that — it’s awesome!

FDA Ends Probe into Kratom Salmonella Link

By Pat Anson, Editor

The Food and Drug Administration has ended its investigation of a small salmonella outbreak linked to kratom – but not without taking some parting shots at the herbal supplement used by millions of Americans to treat chronic pain, addiction, depression and other conditions.

“It appears the salmonella problem with kratom uncovered earlier this year has probably been occurring for some time and is ongoing. We have closed our outbreak investigation, concluding that anyone consuming kratom may be placing themselves at a significant risk of being exposed to salmonella,” said FDA commissioner Scott Gottlieb, MD, and Stephen Ostroff, MD, FDA Deputy Commissioner for Foods and Veterinary Medicine, in a lengthy joint statement.

bigstock-Mitragynina-Speciosa-Or-Kratom-229830793.jpg

The FDA ended its investigation five weeks after the Centers for Disease Control and Prevention wrapped up its own probe of the salmonella outbreak that sickened 199 people in 41 states. The CDC investigation began in February of this year, but salmonella illnesses linked to kratom were traced back as far as January 2017.

No single source of the outbreak was ever identified, but kratom was considered the “likely source.” A little over half of the 81 kratom samples that were analyzed tested positive for strains of salmonella bacteria.

“This means that users of these products had essentially a one in two chance of being exposed to this pathogen,” Gottlieb and Ostroff said. “The more than 50 percent contamination rate is stunningly high. It represents a level rarely seen in outbreak investigations of this nature. It shows that a high proportion of kratom being shipped into the United States may be contaminated with salmonella.”

Kratom comes from the leaves of a tree that grows in southeast Asia, where it has been used for centuries as a natural pain reliever and stimulant, particularly in rural areas of Indonesia and Thailand.  

“In these locations, the plant is being grown, harvested and processed in problematic conditions that readily create the circumstance for widespread contamination with foodborne pathogens. Although some of the kratom is further processed once in the United States into capsules, powders or herbal remedies, based on our findings, these procedures do not appear to be eliminating microbial contamination,” wrote Gottlieb and Ostroff.

In recent years, millions of Americans have discovered kratom and started buying it online or in convenience stores and “head shops.” But not until this year did federal health officials show any concern that kratom products were contaminated with salmonella bacteria. Their primary focus was that kratom was being marketed as an unapproved medical treatment, particularly for pain and addiction.

The FDA has even started calling kratom an addictive “opioid,” when in reality its active ingredients are mitragynine and 7-hydroxymitragynine, two alkaloids that are believed to act on opioid receptors in the brain. Earlier this year, the FDA released a computer analysis that found kratom contains over two dozen opioid-like substances – a report that critics say was biased and amounted to “junk science.”

Over a dozen kratom products were recalled during the FDA and CDC salmonella investigations. Salmonella is a bacterial infection usually spread through contaminated food or water. Most people who become infected develop diarrhea, fever and stomach cramps. Severe cases can result in death.

There have been several other salmonella outbreaks this year, including infections linked to melons, raw sprouts, dried and shredded coconut, live poultry, chicken salad, pet guinea pigs, and Kellogg’s Honey Smacks cereal.
