Twelfth graders were first asked about past-year use of Spice (synthetic marijuana) in 2011. Annual use was 11 percent, making synthetic marijuana the second most widely used class of illicit drug after marijuana among 12th graders. However, starting in 2013, use of synthetic marijuana has continually dropped. In 2019, about 3 percent of teens in 8th, 10th, and 12th grades report that they used Spice in the past year. The chart below shows the percentage of teens who use Spice.
