    • Pharmacology

    Background:

    • Cannabis has historical recreational and medicinal uses.
    • Recent scientific advances have significantly improved understanding of cannabis and cannabinoid effects on the brain.

    Purpose of the Study:

    • To review the current knowledge of how cannabinoids affect the brain.
    • To highlight the role of the endocannabinoid system in CNS function.

    Main Methods:

    • Review of current scientific literature on cannabinoid action in the central nervous system.
    • Analysis of cannabinoid receptor signaling, synaptic modulation, and cellular targets.

    Main Results:

    • Cannabinoids act via CB1 and CB2 receptors, with CB1 mediating most central effects.
    • Evidence suggests a new type of brain cannabinoid receptor.
