Every time the ghastly violence of prohibition is falsely blamed on the users, it diminishes the culpability of those who are truly responsible for maintaining the status quo. Prohibition is an absolute scourge—the end! The use of drugs is NOT the real problem, the system that grants exclusive distribution rights to violent cartels and terrorists IS.
When governments prohibit drugs they effectively and knowingly hand a monopoly on their sale to dangerous criminals and terrorists. Without a legal framework in which to operate, these black-market entities can always be expected to settle their disputes violently, while terrorizing many peaceful and innocent citizens in the process. Were the users of alcohol to blame for the St Valentines massacre in 1929? Of course not! It is just as naive to assume that one can compel all the users of Marijuana or Cocaine to simply quit, as it is to assume that all the users of Alcohol should have stopped drinking after the introduction of alcohol prohibition in 1919.
Nobody can be expected to obey bad laws, like ones that infringe on logic as well as the fundamental right to decide on what medicine or poison an individual adult may, or may not, ingest. The violence and the deaths ultimately arising from such bad public policy should always rest squarely on the shoulders of those ignorant imbeciles who are responsible for implementing and supporting such foolishness.
