A new study of more than 20,000 Americans published in the scientific journal Addiction has found that once a state legalizes recreational cannabis, state residents are more likely to start using the drug. The study compared four US states with legalized recreational cannabis (California, Massachusetts, Nevada, and Maine) with states that had not.
This study is groundbreaking in four ways:
Professor Yuyan Shi of Herbert Wertheim School of Public Health and Human Longevity Science at University of California San Diego, the Principal Investigator of this study, says “Our findings provide useful information to policymakers and public health practitioners interested in understanding the consequences of legalizing recreational cannabis. It’s especially concerning that increased cannabis use occurs among young people because of the detrimental health effects associated with cannabis use at a young age, including impaired respiratory function, cardiovascular disease, and adverse effects on mental health.”
