Why Teenagers fall into the pressures of Alcohol?

About a year ago, when someone would tell me they tried beer, I would think they fell into peer pressure and could not handle themselves well. Over the summer everything changed for me. I started hanging out with kids who do all that "bad stuff" and I got a completely different view on everything. The first time I was around them drinking I really tried to imagine why they wanted to do this so bad. None of them were pressuring each other to do it. They just did it because they liked how it made them feel. I was never pressured to try some drinks. My friends did not care if I did it or didn't. Back to my original question, why did they like doing this so much. It made me extremely curious. Of course peer pressure is a major reason why teens drink but i think curiosity is actually a better explanation. Especially in my case. I looked online, does alcohol make you feel good and happy? I got nothing besides yahoo answers. I only heard good feedback from my friends and annoying health facts from school that I do not care about. I think if I was less curious, I wouldn't be thinking about trying it. If parents and teachers told me it makes you happy I would just think ok a lot of things make me happy so i could just keep doing that. So I am not saying people should go around promoting how great alcohol is, I just simply want to know how it does make you feel great. And i do not want people saying I try it because of peer pressure anymore because that annoys me. haha
