I disagree that drugs (including alcohol) and women are either cheap or a good idea. They are temporary vices that cause for your tomorrow to be degraded at the cost of momentary pleasure. This cost is both immense in that you pay for the vice both now with your money and time, and with drugs possibly legally, and later. The cost later includes various issues such as possible health problems such as addiction or diseases, possible allegations from women as seen in cases such as DSK and the plethora of sexual harassment allegations in industry, and with lost opportunity. The time you spend on these vices could be better spent on self improvement, learning a new skill, practicing something to get better, or actually doing something that allows you to have more than a momentary pleasure.
