what i am saying by the comparison, is that it depends on the person. alchohol can be just as bad as meth, given those 2 variables. i have seen more than one person take a shot or 2, and not be able to quit drinking until the ability to access alchohol is forceably removed. i have also seen a small hand-full of people able to do meth 1-3 times in a row, and then be done with it, for good, or for now. to put in prespective- i take 3-4 vicodin on a daily basis with little effect. i also like to drink in the evening, usually only 1 rum&coke, maybe 2 sipping. however, sometimes, i will actually want a buzz, or to get drunk. i start to feel it with 1/2 a 5th in a couple hours, but to actually set just enough drunk, it requires a full 5th in under 4hours. that is just my natural tollerance to things. now, my bro, he is a lightweight. only takes about 6shots, and he is psyco. been to jail for b&e and a few other things. nothing he would normally do, and does not drink anymore, aside from 1-2 social mixed drinks. i have met several others like that. you are pretty right about typical scenarios, but not everyone is typical
