How Does Marijuana Impact People's Mental Health? [with Stats]

78 percent of marijuana users report the plant positively impacts their overall mental health. A separate question finds that cannabis also positively impacts their happiness (79%) and makes them more social (63%). Very few thought it negatively impacted their mental health (4%) or happiness (3%).


These statistics are from Drive Research's Cannabis Consumer survey with 3,926 marijuana users across all 50 U.S. states, conducted in March 2023. 

Those who earned a Doctorate degree (89%) and those who spend on average $100 or more per cannabis purchase (88%) were more likely to indicate a positive impact.

Survey Methods

Results from this Drive Research poll are drawn from an online survey conducted in March 2023 with a sample of 3,926 cannabis consumers across the country. The survey took an average of 9 minutes to complete and included 47 questions. 

With a probabilistic sample, a total of 3,926 responses at the 95% confidence level offers a 1.6% margin of error. For instance, if the survey were conducted with another random pool of 3,926 respondents, the results would yield within +1.6% or -1.6% of the stated totals in the reports.
