Drugs that can affect the...
The "subjective high" from marijuana ingestion is likely due to Δ(9)-tetrahydrocannabinol (THC) activating the central cannabinoid receptor type 1 (CB1R) of the endocannabinoid signaling system.

On the other hand, psychostimulant abuse and dependence lacks pharmacological treatment.

Executive functioning deficits are reported in ecstasy users. However research into mental set switching has been equivocal, with behavioral studies suggesting the function is preserved.

Twenty ecstasy...
