Drug Flashbacks. II. Some Additional Findings

Abstract

A subsample was drawn from an earlier collection of data in order to answer a number of questions related to "acid" [LSD, STP or DOM (4-methyl-2,5-dimethoxy-.alpha.-methylphenethylamine)] flashbacks. Acid users who reported flashbacks also reported significantly more marihuana use than those who did not; the 2 groups did not differ on use of other drugs, including acid. Simple correlations and multiple regression analyses both showed extent of marihuana use to be the only drug variable significantly related to acid flashbacks. No optimal combination of marihuana and acid improved flashback prediction. Among acid users, correlations between amounts of use for various drugs were high and significant, excepting only the marihuana-acid correlation.
