The marihuana substances were judged as calming as opposed to exciting, relatively safer, and less potent than psychedelic drugs. In this study and others it seems that marihuana may be more similar to sedative, depressant, and hypnotic drugs than to psychedelic drugs. Some superiority in correct classification was found for a non-linear discriminant function over a linear discriminant function.

Alcohol and some legal drugs were included as well as drugs of abuse. Guttman scalogram analyses yielded very high coefficients of reproducibility (.89 to .98). The pattern of drug use was cross-validated on a sample of young drug users in another setting. The relative frequency of drug use for our sample was also highly related to that reported in other studies of student populations. In order to identify the dimension underlying the pattern of drug use, ratings of the safety and availability of each of the 18 substances were obtained. Both availability and safety were highly related to the relative frequency of drug use, with availability being the more important variable.

Heroin chipping, or occasional use, showed a peak time, 6 P.M. to 10 P.M., coinciding with the most common time for use of a variety of substances in several populations. However, the habitual use of heroin is most common upon awakening--apparently to ward off withdrawal symptoms. The results also suggest that the use of marijuana and alcohol does not deviate significantly from the recreational pattern of drug use demonstrated by other populations for other nonprescribed drugs.

Addicts' own experience and that of ex-addicts and other users were the most trusted sources; and mental health professionals were significantly less credible than sources with personal drug experience. The findings support the use of paraprofessionals in drug education and drug counseling.

The set oriented toward the recall of a psychedelic experience produced markedly elevated profiles, particularly on scales reflecting altered perceptions of the world and changes in the body image.
