    This summary is machine-generated.

    Heavy and moderate cannabis users showed reduced activity and increased sleep following consumption. These effects, linked to delta-9 THC, disappeared after use ceased, suggesting a dose-related response to cannabis.

    Area of Science:

    • Psychopharmacology
    • Behavioral Science

    Background:

    • Cannabis use, particularly delta-9 THC, is prevalent.
    • Understanding the behavioral effects of regular cannabis use is crucial.

    Purpose of the Study:

    • To investigate the effects of sustained cannabis access on behavior.
    • To examine dose-related responses in moderate and heavy cannabis users.

    Main Methods:

    • Systematic observation of sleep and activity in adult male volunteers.
    • Controlled 21-day period of cannabis cigarette access (2% delta-9 THC).
    • Comparison with a control group of casual alcohol drinkers.

    Main Results:

    • Both user groups exhibited reduced activity post-cannabis and increased sleep following heavier consumption.

  • Heavy users showed sustained activity reduction during cannabis availability.
  • Behavioral changes ceased after the 21-day period.

    • Conclusions:

    • Cannabis consumption leads to dose-related behavioral changes, including reduced activity and increased sleep.
    • These effects are temporary and reversible upon cessation of use.
    • Acute effects may also be influenced by social context, not solely pharmacology.
