Cannabis isnt a stimulant, but it is stimulating.
But heres the citation:
Other articles exist, but they mostly seem to come from the same study.
Amphetamines, cocaine, MDMA and other ecstasies (MDA, whatever).
Cannabis and alcohol are used more by intelligent people as well, but downers in general are not used for the same reasons as uppers are. Although cannabis, being a very weak psychedelic, could be considered stimulating.
The reason I specifified stimulants and cannabis is because overall, stimulants and cannanbis have the highest increase in use with IQ, where as downers have a lot less.
Although alcohol is used more with intelligent people as well, alcohol and benzos generally are used as coping mechinisms, and downers in general. Psychedelics, amphetamines, dissosiatives, empathogens, arent good for coping to begin with.
The reason I figured a study with raves would be helpful is because raves are, in general, heavily stimulating. If you crave a lot of stimulation, you would enjoy raves. If overstimulation is a problem for you, you would avoid them. Unrelated to the widespread drug use in them, more because they are some of the most stimulating events.
Yea, the rave thing isnt related to drug use. I proposed it because I cant think of any type of event that stimulates as much as raves.
