That's because alcohol is nowhere near as expensive as hard drugs are. You can get a fifth of vodka for as cheap as $10 vs. a gram of heroin that costs about $100 (I stopped doing this a while ago so don't try to preach to me about it). Keeping drugs illegal inflates the prices a lot, if they were legal it wouldn't be like this.I have yet to read about alcoholics killing their mothers for a few bucks for more booze.
You have obviously never seen real alcohol withdrawl, it can get much worse than any other drug, even methadone.I have seen what happens to a friend when he trys to resist taking 2 mg of a methadone type drug. He starts to feel hot and sweat begins to pour from his body. He feels sick and weak.....light headed. His body cramps. This from 1/4 the full dose as he has weened himself down painfully and over much time. The differences between pot and alcohol compared to the hard core drugs is night and day.
