Marijuana Awareness

Marijuana is an illicit drug made up of the dried leaves and female flowers of the cannabis sativa plant. This substance, although legalized for restricted personal use in some states and currently on Guam, is classified as a Schedule I substance by the federal government meaning that it is considered to have a high potential for abuse, has no currently accepted medical use in treatment, and there exists a lack of acceptable safety for its use under medical supervision. According to the Guam Epidemiological Profile 2021 update, in 2019:

  • One in Five (20.5%) middle schools students had ever used marijuana.
  • Nearly half (45.3%) of all high school students have tried marijuana, and One in Four (25.9%) has used marijuana within 30 days of the survey.
  • Lifetime marijuana use among high school students in Guam remained higher than in the US, but current prevalence is similar.
