Question by DJ: Which of these illicit drugs is the most brain damaging?
I’m doing a research project for psychology and the topic is about neurology. I came across an interesting graph on this site:

But the graph is ranked by physical addiction and physical harm but not brain damage. My question is which drugs from the following list causes the most brain damage (negatively effects cognitive ability, concentration, and ability to learn; instead of just causing physical dependence) in the long term and not just under influence or coming down from the effects

Mushrooms
LSD
Alcohol
Cocaine
Meth
Any other drug listed on the above website
