Unless you're like a closet alcoholic that sits at home every night and gets drunk (no offense if you are, I wish I could live that life) drinking is more about the social aspect than anything. Be it a house party, frat party, bar or club, the point is to have a good time in the company of other intoxicated individuals. I haven't blazed after drinking, or with the intent of drinking, anything over 10 brewski's in a night since back in like 8th grade because it literally would have me falling asleep standing up.
The main difference between being hammered and blazed as far as I'm concerned is noise. When you're drunk it's OK to be loud as shit and guido fistpump the air every time one of your jams come on. It's OK to be falling over people, knocking pong cups down, laughing loud and just having a good time with people that feel the same as you do. I smoke daily (half the time alone because I hate working sober), and drink prolly twice a week, and definitely prefer being smashed and loud to blazed and introspective.
