You're doing pretty much exactly what I'm saying, you're downplaying alcohol by saying, well its just because its so widespread. That is the point. Just because alcohol isn't as dangerous as heroin and meth individually doesn't mean its not doing more damage to society, and yes the main reason for that is because it is so widespread.
Also, you don't have to be an alcoholic for you to be damaging yourself or others with it. That is another big fallacy that some people use, "I'm not an alcoholic so its not a big deal if I drink myself stupid a night or two a week", which is just stupid. There are a lot of people that go to college and have years of binge drinking. Some stop, some don't. Both have damaged themselves. People like to act like its not a big deal (actually there's a lot that act like its a good thing). That is the point, is to understand that it is a bigger deal than people accept. Ritualistic binge drinking doing just as much damage to your body as going on coke (or other drug) benders every so often, but people don't want to admit that. Its even become socially accepted to brag about your excessive drinking, whereas you'd get frowned on if you said, yeah, so I did a line of coke, or dropped acid, or ate some shrooms.
There are actually a lot of people that are casual or even regular users of cocaine that are not addicts. Yes, it is more addictive, and other drugs are even worse, but you hear the government cracking down on drugs, smoking, food even, but not alcohol (drunk driving, sure, but not alcohol consumption). Oh, I guess they did make them start adding "please drink responsibly" to their ads, but that's about as effective as those shitty anti-pot commercials.
I'm curious if they lumped crack in with cocaine in the study.
