I think it depends on your relationship with alcohol in the first place. I got drunk for the first time when I was 13, and my use of alcohol has gradually increased ever since. I am now 20 years old, and get shitty at least twice a week during school, usually 6-7 nights a week during the summer. So if you are like me, steady alcohol use eventually becomes something like a cigarette habit. In other words, you keep smoking (and drinking) regardless of what other drugs you choose to use. I was drinking before I ever used drugs, but it was only a year after that I started smoking pot (which I have done on and off ever since). Other than that, I didn't roll or trip or anything like that until I was 18. If anything, I probably drank more when I was rolling just to deal with the depressed feelings between rolls.
But then there are other people who never made drinking a part of their social life (high school is the critical time that this happens, if you are 25 when you first get drunk, you probably aren't going to end up an alcoholic or maybe even a drinker). Thus, they approach it and talk about it in terms of a high or experience. Of course alcohol is drug, but in some respects it is more like cigarettes than other drugs. You don't hear people talking about the "high" you get from smoking cigs or writing trip reports about nicotine. For most regular drinkers, it is just another part of their lifestyle, and a major component of their social interactions (parties, football games, clubs, etc).
So what I am saying is that people like me will continue to drink as they normally did while people looking for an "experience" will quickly find out that MDMA is more worthy of a trip report.
