Though marijuana use is increasing among older Americans, "most of these people are not first-time users," said Joseph Palamar, senior study author and an associate professor in the Department of Population Health at New York University Langone Medical Center.
"We found high rates of unhealthy substance use (tobacco, alcohol, prescription drug misuse) by middle-aged and older adults who use marijuana," Dr. Benjamin Han, lead author of the study and an assistant professor at the New York University School of Medicine, wrote in an email.
Christopher P. Salas-Wright, an assistant professor at the Boston University School of Social Work, said the new study provides "high-quality information" that is essential in a time when public opinion and policies related to marijuana are changing rapidly.
That said, a number of "credible studies" already provide "compelling evidence that marijuana use has increased meaningfully among adults in general, and among middle-aged and older adults in particular, over the last 10 to 15 years," said Salas-Wright, who was not involved in the new study but has published research on the topic.
Choi, who did not participate in the new research, said a 2017 report from the National Academies of Science, Engineering and Medicine "summarizes very well how little scientific evidence we have so far about marijuana's effects on health and mental health in adulthood."
