Marijuana Use Across the Nation
Marijuana continues to rank first among the most used illicit drugs in the United States. According to SAMHSA's 2014 National Survey on Drug Use and Health (NSDUH) (PDF–3.4 MB), marijuana use was most prevalent among people age 18 to 25. Among youth, heavy cannabis use is associated with cognitive problems and increased risk of mental illness.
SAMHSA addresses marijuana use among youth with its seven-session cognitive behavioral therapy approach, which offers strategies for teaching coping skills to teen marijuana users.
