If drugs and prostitution were the problem, there would a hundred riots in the US everyday. Last I checked, the rioting and the overall bad security situation was due mainly to religious extremism/TTP/Secterian Organizations and the bad economic situation (bleak future prospects, rising cost of living etc). In fact, even religious extremism is related to the economic situation. I don't know what the hell you have been smoking, but there has never been a riot because of prostitution.
