Of course there were. Even today there are alcoholic bums that will mug you for booze money. You don't really think they are all crack or smack fiends, do you? Heroin withdrawal can make you wish you were dead, alcohol withdrawal can make you dead.
More troubling however is community-consuming gang violence. The sort that we see today and the sort that we saw during prohibition.
Safe to assume a very small percentage of alcohol users, which makes the difference here. Safe to assume that during Prohibition the vast majority of alcohol users could have been sober during working hours to pay for it.
The vast majority of cocaine and pot users live outwardly normal lives too. That isn't the point though, is it? Prohibition railroads people who were in control of their habit, it gets in the way of assistance to people who are losing control of their habit, and it further marginalizes and radicalizes people who have already lost control of their habit, and it dramatically radicalizes those who provide for habits.
This myth of "alcohol is not a 'hard drug'" needs to die. Prohibition of alcohol wasn't somehow a different animal than the prohibition of other drugs, you just relate to alcohol more than you relate to cocaine.
Well, there is one difference between alcohol and other 'drugs' (with the possible exception of pot): alcohol has been a mainstay of human culture for a long time. The same can't be said of cocaine, heroine, meth, etc.
