How common is it?
Among students in grades 7 to 12, two thirds report using alcohol, one quarter report marijuana use, and about 15% report using tobacco. Alcohol and tobacco are the most frequently used legal substances.
Marijuana (also known as cannabis or pot) is the most common drug used by those students who use illegal drugs
frequently (6 or more times a year). Only 2% of children and teens are frequent users of other illegal drugs, such as stimulants like methamphetamine, hallucinogens (other than LSD or PCP), cocaine, or Ecstasy.
