That said, alcohol is even worse for people losing control of their actions but at least the crimes they commit are not so evil as those committed by druggies.
I think that's totally wrong. Think of all the violence and physical abuse caused by alcohol intoxication. I bet more people have been killed by someone in a fit of alcoholic rage than desperate druggies trying to get a fix.
Druggies are everywhere, in all professions - lawyers in particular have a fondness for heroin. It's just that they have the funds to finance their habit and don't generally have to resort to the desperate measures that poor people do.
