WORCESTER, Mass. —
For families witnessing loved ones struggle with psychosis or addiction related to heavy cannabis use, the warning signs are often clear. However, new data indicates that most Massachusetts residents remain unaware of the potential mental health risks associated with regular marijuana use.
A survey published Friday by the Massachusetts Cannabis Control Commission highlights significant gaps in public awareness years after the state legalized recreational marijuana. The survey, conducted between 2019 and 2023 with over 11,000 Massachusetts residents, found that many people do not realize that frequent cannabis use can increase the risk of serious psychiatric conditions.
When asked if regular marijuana use can raise the risk of psychosis and schizophrenia, only 20% of participants correctly acknowledged that such a risk exists.
Medical professionals treating young patients say the survey’s findings align with their clinical observations.
Dr. Scott Hadland, chief of Adolescent and Young Adult Medicine at Mass General Brigham for Children, treats numerous patients experiencing severe effects from heavy cannabis use.
"The survey found that about one in five people understand that cannabis can lead to psychosis or schizophrenia, which is something we frequently see in clinical settings and are deeply concerned about. In recent years, especially among young cannabis users, we've observed an increase in cases where patients develop psychosis and require emergency or clinical care after cannabis use," he explained.
Dr. Hadland noted that legalization might contribute to misconceptions, as many assume that legal substances are harmless.
"It is crucial for people to understand that cannabis carries significant downstream risks when used heavily by young individuals. We need broader public health messaging to effectively communicate this information," he added.
The Cannabis Control Commission’s report also emphasizes the need for expanded public education. Although state law mandates "science-based public awareness campaigns" about marijuana’s health risks, lawmakers have not allocated funding for such campaigns in recent years.
In its latest report, the commission urges dedicated funding or a coordinated statewide effort to better inform residents about cannabis’s potential mental health risks.
