Very soon people are going to claim that hard drugs like cocaine and heroin has some medicinal properties and they are going to advocate that people start using it and soon it would be widely accepted the same way that Marijuana is going to be accepted.
That's funny you say that, because according to the government, both cocaine and heroin both are classified as having some medical benefit while marijuana is classified as having none. Cocaine and heroin have a long history of medical use. That said, drugs are bad mmmkay. What is worse though is a tyrannical government dictating to everyone what they put in their bodies, and using possession of a substance as an excuse to steal, imprison, torture, and strip human rights. Prohibition does far more damage than addiction ever could.
