Well howabout this cocaine will scar your heart muscle, and weaken it. Weed is such an incredible drug because it's completely safe, but very effective in getting you high. And besides, don't they refine coca leaves in gasoline? That can't be too good.
Cocaine is cardiotoxic, but since most of what is known about this is anecdotal or based on animal research the extent to which it occurs in humans remains unknown.
Another substance exhibiting cardiotoxicity in humans, ethanol, remains very popular.
Gasoline plays no role in the production of cocaine.
Here is a kind suggestion, before you decide to post any more bullshit why don't you look it up first?
