Why do you wish to continue sentencing addicts? Should we sentence you for all the booze you need to write rubbish like this?
Maybe you believe that it's immoral to use a certain drug. If so, would you care to explain to us why you think that alcohol or tobacco is exempted from your personal moral condemnation. And even then, you still need to explain why you think it should be a crime to imbibe certain plants and not others.
Prohibition means that these certain plants/concoctions/drugs are sold only by criminals and terrorists who are heavily armed. This is a direct result of this failed policy which guarantee that those who sell drugs cannot defend their business interests in the usual legal way.
law enforcement and rehabilitation are mutually exclusive. Would alcoholics seek help for their illness if doing so were tantamount to confessing to criminal activity? Likewise, would putting every incorrigible alcoholic behind bars and saddling them with criminal records prove cost-effective?
Further, it simply cannot be mandated that people give up drugs in order to receive help. The abstinence mandate keeps the majority of candidates away. What then occurs is that people with drug problems continue to use drugs in a way that presents a high risk of health problems to the individual user.
And don't forget, nobody wants to see an end to prohibition because they want to use drugs. They wish to see proper legalized regulation because they are witnessing, on a daily basis, the dangers and futility of prohibition. 'Legalised Regulation' won't be the complete answer to all our drug problems, just as the end of alcohol prohibition in the US didn't end all the problems associated with alcohol use/abuse. But it'll greatly ameliorate the crime and violence on our streets, and only then can we provide effective education and treatment.
