> Why do you think alcohol does less harm then any of the others?
A simple test, give each to a baby/small child and see what happens... I lived in a time where babies were given tiny amounts of alcohol for pain relief and it did no harm that I ever heard. I doubt you can say the same for meth.
You are mistaken. Vast numbers of American teens are prescribed amphetamines every day. The main difference between elicit recreational methamphetamine use and medical/psychological amphetamine use is circumstances and dosing. Kids on Ritalin are generally in safe situations where they have consulted a psychologist with the involvement of their parents, and are given a pure, unadulterated, small, carefully dosed amount of amphetamines. Meth addicts are typically people with more serious mental issues and in precarious situations, given massive and uncertain doses of unpure, perhaps adulterated amphetamines.
The disparate outcomes of those groups are much more about the dosage and the personal/social situation.
Pharmacologically, they are pretty much the same drug.
I believe that the consensus is that it did cause a small amount of harm and there likely are horror stories you never heard, that's why the practice stopped, but giving children meth is called adderal.
Children also had regular access to small amounts of coke and heroin probably in your grandparents or great grandparents life, remember Coca Cola and laudanum was used for teething. You've never heard of harm from that. Your test says all of them pass.
