U.S. High School Seniors’ Perception of Harm from Regular Marijuana Use Decreasing

In the United States twelfth graders’ perceived risk of harm from regular marijuana use has declined in recent years, according to data from the national Monitoring the Future (MTF) survey.

This process is a well-known “fact”. When the risk of using marijuana is presented and perceived as low, perception of harm as well as use increase. However, this does not make marijuana any less dangerous.
