"If prohibiting drugs works so well,.." You are hallucinating. I didn't say it works "so well". And I'm not going to say so now because I'm not a mindreader and therefore I don't know what you mean by "so well". "..why is it that a teenager can get pot at least as easy as alcohol?" That statement defies understanding due to your sloppy and fuzzy wording (and thinking). If you mean that "a teenager" somewhere in the U.S.A. can easily get pot, you are correct. If you mean all teenagers can easily get pot, that is not true.
