What did the Monitoring the Future (MTF) survey show regarding marijuana trends in 2019?

The Monitoring the Future (MTF) survey for 2019 indicated notable trends in marijuana use among adolescents. The data showed an increase in daily marijuana use specifically among younger grades, which reflects a concerning shift in usage patterns among this population. Simultaneously, the overall usage rates showed a steady decline, providing evidence that while daily use is rising in certain demographics, the total number of students using marijuana overall was experiencing a decrease.

This combination of findings underscores the complexity of substance use trends, where certain segments of the population may be engaging more heavily with a substance, while the broader trends might indicate a reduction in use. By reflecting both the increase in daily usage among younger demographics and the decline in overall usage rates, the survey highlights the nuanced landscape of marijuana consumption in recent years.
