    Area of Science:

    • Psychopharmacology
    • Cannabis Research

    Background:

    • The influence of environmental setting on drug effects is a key area of psychopharmacological research.
    • Understanding the variables that modulate subjective drug experiences, such as cannabis, is crucial for accurate assessment.

    Purpose of the Study:

    • To investigate the role of environmental setting in modulating the subjective effects of marihuana.
    • To differentiate the impact of the drug itself from the influence of the surrounding environment on user-reported experiences.

    Main Methods:

    • 12 subjects participated in a controlled study.
    • Subjects smoked either marihuana or placebo cigarettes in two distinct environments: 'favorable' and 'neutral'.
    • Subjective effects were measured using the linear euphoriant scale and the Addiction Research Center Inventory (ARCI).

    Main Results:

    • Statistical analyses revealed significant effects attributed to individual subjects and the drug (marihuana).
    • No significant effect was found for the environmental conditions on reported marihuana experiences.
    • Subjective reports were strongly influenced by individual psychological (mental set) and biological variations.

    Conclusions:

    • The immediate environment appears to play a minimal role in the subjective effects of marihuana.
    • Individual psychological and biological factors are the primary determinants of how marihuana effects are perceived and reported.
