I am a user of drugs myself and I see a lot of problems with the current system, and I'm afraid Donald Trump will not be fixing them. Drug use has been stigmatized for a long time and that stigma won't go quietly. Drug users are also filling up jail systems only to be forced into rehab where they are fed the bullshit of the disease model of addiction.
I feel that drugs should be freely available as alcohol is, even "bad" ones like heroin, meth, and PCP. The effects of these drugs should be made widely available to the public in a non-sensationalistic or overexaggerated way. But people (like me) who use them should have to be responsible for their choices and not be given a free pass via "Oh I have a disease now and can't control my use."
Rehab programs should be pushed to throw out Alcoholics and Narcotics Anonymous from their program and incorporate Rational Recovery.
