Marijuana, hashish and THC belong to which drug category?

Depressants/Sedative-hypnotics Stimulants Hallucinogens/Dissociatives Cannabinoids/cannabinols

Correct Answer:

Cannabinoids/cannabinols

Explanation:

Marijuana, hashish, and THC are cannabinoids. They act on the endocannabinoid system, with THC as the primary psychoactive component. Cannabinoids bind to CB1 receptors in the brain (and CB2 in the immune system), altering neurotransmitter release and producing effects such as relaxation, altered perception, increased appetite, and analgesia. This receptor-based mechanism and the characteristic effects distinguish them from depressants (which slow CNS activity), stimulants (which raise energy and alertness), and classic hallucinogens/dissociatives (which alter perception through other systems). Hashish is a resin rich in cannabinoids, especially THC, while marijuana refers to the plant and its preparations; together they’re categorized as cannabinoids/cannabinols.
