How is Prohibition of any product justifiable in a "Free Country"? Why shouldn't I be able to sell or ingest?

I think you have to ask yourself, "how responsible am I with the use of drugs?" The reason why prohibition was implemented during the 1920's is because at that time alcohol was at an all time use in terms of consumption. As a result you had people abusing it, and the government had to step in. The reason why prohibition didn't work was because it sparked m violence and riots in response to the law. So the ban was lifted. Now in terms of today, drug use as it relates to marijuana and other narcotics are illegal because of its harmful effects. Although alcohol is harmful as well when abused, the effects of those drugs outweigh that of alcohol. Think about it. You have users who have literally died, and some who will never be the same because of being high. Sure you might say that alcohol can cause the same or similar problems. But the long term effects are far greater with narcotics.
