least harmful drug on the brain?

Question by hal n: least harmful drug on the brain?
in terms of ability to damage intellect, which drug has the highest potential make you stupid. this is what i think.
marajuana- memory dissolution comes to fruition, devreasing intellect considerably.
alcohol- kills brain cells, loss of intellect after enough drinking.
cocaine- not sure, alot of intellects (sigmund frued among others) used this drug extensively.
heroin- granted addiction, but aside from that it doesn’t make you stupid or anything. probably the best drug for the brain.
meth- induces psychosis and damages brain, brain damage no doubt.
ecstacy- changes neuropathways in the brain, a definite deficit of intellect.
lsd- hallucinations may persist, and while not conclusive people who overuse acid tend to become fried.
mescaline- organic deemed completely safe by recent harvard study using native americans.

Best answer:

Answer by The Salesman [Evolving]
In reality, alcohol, cigarettes, and tv are probably the worst drugs out there for our brains.
Meth will crumple the brain, like, for sure.
Heroin will not destroy your brain, but will instead destroy your life.
Ecstacy has fried a few people I’ve known, so I stay away.

The rest are game on.
The risk of psychosis being developed by any hallucinagenics is a small risk compared to the benefits most receive from its use.

I have no knowledge of mescaline.

Coke is dangerous because of the low longevity of the high, which is probably why so many OD on it.

Weed is probably a little worse for you than hallucinagenics but isn’t nearly as bad as TV or Coffee.
