I'm not answering for jtk4, but it seems the party drug of choice these days is coke, ecstacy is becoming less and less popular. Some people get a euphoric feeling from coke, some don't, I'm one of those that don't. However, it does make you more social, gives you energy, and boosts your self esteem a lot which is why most people like it. I've seen extremely shy people do weird shit like stand up on tables in a club and yell "I am the Lizard King!" after doing just a few lines. This is why a lot of celebrities are cokeheads, most are insecure and love the confidence boost. The burger analogy was good, but its not the case with everyone. I can go out and have just as good a time without drugs... its just a different type of fun.
