There are many people who can have a few drinks, get the positive effects, the warm glo, release from inhibitions etc.etc. and let it go at that. For that group I think it can be a most enjoyable thing, not a problem at all. Alcohol is highly addictive tho and for those with a broken "off switch" the same few drinks are like lighting the fuse, buying a ticket to the haunted house of hangover hell. Same substance, very different results.
