Some people think that they know best for others, and say marijuana users are criminals because they don't know better. I do agree that drugs are a serious sign of the possibility of mental or physical health problems. We need to move the drug use problems into the health care field. The War on Drugs is an utter failure. Billions of dollars later, drugs are still available, and we have a small nation unto itself in our prisons.
Prevention is the key.
Education on the effects of drugs is crucial. After that, let consenting adults do what they want. We don't persecute alcohol users because they are merely more socially accepted. Logically, the United States has only one option to rectify its wrongs. It must free the prisoners of the Drug War that just smoked a joint instead of having a beer.
