Alcohol and Marijuana Use in Adolescents' Daily Lives: A Random Sample of Experiences

Abstract
High school students filled out reports on their experiences at random times during their daily lives, including 48 occasions when they were using alcohol or marihuana. Alcohol use was reported primarily in the context of Friday and Saturday night social gatherings and was associated with a happy and gregarious subjective state. Marihuana use was reported across a wide range of situations and was associated with an average state that differed much less from ordinary experience.
