The Number 1 Gateway Drug

I read an article today about teens that smoke cigarettes are more likely to develop drinking and/or drug problems. The article suggested that because smoking at such a young age messes with the chemistry and brain function, that makes them almost twice as likely to drink and almost three times as likely to smoke marijuana.

Now I can relate to this because I first started smoking around 15, then quit for a year or two, then picked it up once more. The second time I started smoking, my drinking had picked up about double what it was the year before. This information, in my opinion makes sense. The other thing is, it makes me ask the question what really is the number 1 gateway drug?
