I have a moral opposition to mind-altering drugs in the quantities necesary to achieve such an effect. I also hate the idea of chemical addictions. I also believe that at 16 I am not mature enough to be having sex (which is, ironically(?), what makes me more mature than most of the people actually having sex). But while I do not partake in drinking, drug-taking, smoking or sex I am happy, very happy infact. I instead take joy from non-questionable things such as intellectual development, jokes, friendly interactions, gaming, philosophical discussion and immaturity (but in a mature way).
So yeah, I reckon if I did partake in drugs and the like my life, while filled with 'instant' pleasures would not have the depth that brings me a deep and satisfactory happiness. So in truth, while you find it hard to empathise with my position, I find it hard to empathise with yours beyond "Your life is a shallow and empty husk and you use such things as smoking, drinking, sex and drugs as a way of filling the void that you are in denial about possessing". Now that may be horrendously wrong, but that is the only way in which I can understand your situation in much the same way that you find it hard to understand mine.
