Is alcohol an addictive substance?
Yes, it is addictive, and if you become an alcoholic the withdrawal is particularly severe, it can kill you even with hospitalization and causes brain damage. More often than not, it doesn’t lead to serious dependence, but a lot of people can’t control it and end up alcoholics. As someone said, it’s a depressant, rather than a stimulant. It is relaxing in moderate quantitites and it does make you happy, again, in moderate quantities. And it helps you loosen up and have fun; a bit too much makes you forget yourself and do stupid, risky things like having unprotected sex or sex with strangers.
