Marijuana smoking remains the most prevalent form of illicit drug use in the United States, Canada, Australia, New Zealand, and some European countries, and rates of heavy marijuana smoking are high in other countries where accurate epidemiological data are not available (Black and Casswell, 1993; Hall, Johnston, and Donnelly, 1999; Substance Abuse and Mental Health Services Administration [SAMHSA], 2005a, b). In the United States, conservative estimates indicate that more than 14 million people smoked marijuana during the last month, and approximately 25 percent of these smoke almost daily (SAMHSA, 2005a, b). The types of problems associated with regular marijuana use have been well documented. Heavy use has been linked to impairment in memory, concentration, motivation, health, interpersonal relationships, and employment, as well as decreased participation in conventional roles of adulthood, history of psychiatric symptoms and hospitalizations, and participation in deviant activities (Haas and Hendin, 1987; Halikas et al., 1983; Jones, 1980; Kandel, 1984; Rainone et al., 1987; Roffman and Barnhart, 1987). Given the large cohort of frequent marijuana users, it is vital that we have clear, scientific information available concerning the risks and consequences of acute and chronic use of marijuana and other forms of cannabis.
