Marijuana Use by Baby Boomers Growing

By Pat Anson, Editor

Marijuana use by middle-aged and older adults in the U.S. has grown significantly over the past decade, in part because more baby boomers are seeking relief from neuropathy and other painful conditions associated with aging.

In a survey of over 17,600 adults aged 50 and older, researchers found that 9 percent of adults aged 50-64 reported marijuana use in the past year, double the percentage that used it a decade earlier. Nearly 3 percent of adults 65 and older also reported marijuana use, seven times the number that used it a decade ago.



The 2015-2016 National Survey on Drug Use and Health asked respondents about their marijuana use, including when they first used it and whether they used it in the past year. The researchers also looked at several health issues, including substance use and chronic disease.

"Marijuana has been shown to have benefits in treating certain conditions that affect older adults, including neuropathic pain and nausea,” said lead author Benjamin Han, MD, MPH, a professor of Geriatric Medicine and Palliative Care at NYU School of Medicine.

“However, certain older adults may be at heightened risk for adverse effects associated with marijuana use, particularly if they have certain underlying chronic diseases or are also engaged in unhealthy substance use.”

Han and his colleagues say adults who used marijuana were more likely to also report alcohol use disorder, nicotine dependence, cocaine use, and misuse of prescription medications (including opioids and sedatives) than non-users.

The new findings, published online in the journal Drug and Alcohol Dependence, builds on an earlier study by the same researchers that found a significant increase in cannabis use among adults over 50.

Twenty-nine states and the District of Columbia have legalized medical marijuana and a handful of states allow its recreational use. Although today's marijuana users are more likely to be young adults, the baby boomer generation is unique, having more experience with recreational use of drugs than previous generations. Many baby boomers first tried marijuana when they were 21 or younger.

“The baby boomer generation grew up during a period of significant cultural change, including a surge in popularity of marijuana in the 1960s and 1970s. We're now in a new era of changing attitudes around marijuana, and as stigma declines and access improves, it appears that baby boomers -- many of whom have prior experience smoking marijuana -- are increasingly using it," said Han.

Many older adults who used marijuana in the past year (15% of users aged 50-64 and nearly 23% of those 65 and older) reported that a doctor had recommended it to them.

A recent survey by the American Association of Retired Persons (AARP) found that most older Americans think marijuana is effective for pain relief, anxiety and nausea and should be available to patients with a doctor’s recommendation.

Older Americans Rarely Abuse Opioid Medication

Three out of four older Americans who are prescribed opioid pain medication say they take it less often or in lower amounts than prescribed, according to a new national poll. Only 6 percent said they took opioids more frequently or in higher doses than prescribed.

The online survey of over 2,000 adults between the ages of 50 and 80 was conducted in March by the University of Michigan's Institute for Healthcare Policy and Innovation.  The poll was sponsored by AARP and Michigan Medicine, U-M's academic medical center.

Nearly a third of those surveyed said they received an opioid prescription in the past two years, usually for arthritis, back pain, surgery or injury. About half of those had leftover medication.

While most were cautious about their use of opioids, what they did with the leftover meds was cause for concern. The vast majority (86%) said they kept it in case they had pain again. Only 9% threw their opioids in the trash or flushed it down the toilet, and 13% returned it to an approved location.

"The fact that so many older adults report having leftover opioid pills is a big problem, given the risk of abuse and addiction with these medications," said Alison Bryant, PhD, senior vice president of research for AARP. "Having unused opioids in the house, often stored in unlocked medicine cabinets, is a big risk to other family members as well.”

The researchers suspect that many older adults fear that they will not be able to obtain pain medication when needed because of laws and guidelines that discourage opioid prescribing. Several states now mandate that initial opioid prescriptions for acute pain be limited to a few days’ supply.


Ironically, while many older Americans may worry about losing access to opioid medication, nearly three out of four (74%) support restrictions on the number of days and pills that can be prescribed. And nearly half would support laws that require leftover medication to be returned.

The poll also found that doctors do not consistently warn patients about the risks associated with opioids. While 90% of those surveyed said their prescribing doctor talked with them about how often to take pain medication, only 60% were warned about side effects and less than half of the doctors cautioned patients about the risks of addiction and overdose or what to do with leftover pills.

High Use of Opioids by Older Adults with COPD

By Pat Anson, Editor

Canadian researchers have found significantly high rates of opioid use among older adults with chronic obstructive pulmonary disease (COPD), according to a large study published in the British Journal of Clinical Pharmacology. Over half of the patients received a new opioid prescription after their COPD diagnosis.

"The new use of opioids was remarkably high among adults with COPD living in the community," said Nicholas Vozoris, MD, a respirologist at St. Michael's Hospital in Toronto. "The amount of opioid use is concerning given this is an older population, and older adults are more sensitive to narcotic side effects."

The study is based on records for more than 120,000 adults in Ontario age 66 and older with COPD, a progressive lung disease that makes it harder to breathe. COPD causes coughing, wheezing, shortness of breath, chest tightness and other symptoms. Most people who have COPD smoke or used to smoke, according to the National Institutes of Health.

Between 2003 and 2012, 70 per cent of the COPD patients who lived in their own home were given a new opioid prescription, while about 55% of those living in long-term care facilities received a new opioid prescription. Many were given multiple opioid prescriptions, early refills, and prescriptions that lasted more than 30 days.

Opioids might be prescribed more frequently among older adults with COPD to treat chronic muscle pain, breathlessness and insomnia.

"Sometimes patients are looking for what they think are quick fixes to chronic pain and chronic breathing problems," said Vozoris. "And physicians sometimes believe that narcotics may be a quick fix to COPD symptoms."

Common side effects of opioids in older adults include falls and fractures, confusion, memory impairment, fatigue, constipation, nausea, vomiting and abdominal pain. Vozoris says opioids may also negatively affect lung health by reducing breathing rates and volume, which can result in decreased blood oxygen levels and higher carbon dioxide levels.

"This is a population that has chronic lung disease, and this drug class may also adversely affect breathing and lung health in people who already have chronically compromised lungs," he said.

Most of the opioid prescriptions were written by family physicians, usually for pain medications that combine an opioid with acetaminophen.

"Patients and prescribers should reflect on the way narcotics are being used in this older and respiratory-vulnerable population," said Dr. Vozoris. "They should be more careful about when narcotics are used and how they're being used."

A study published in Clinical Interventions in Aging warned about the risk of “polypharmacy” in older adults, who often take multiple medications written by different providers.

“The elderly population is especially challenging when one has to consider all of the pharmacodynamic changes that occur with normal aging. The side effect profile of opiates is similar for all age groups; however the elderly population is at a greater risk for these side effects given their comorbidities and high incidence of polypharmacy. Using opiates appropriately and at the most efficacious dosage for the severity and type of pain becomes crucial in the elderly,” the study said.
