I find reading sites about drug use an endless source of myth destruction. There have always been professionals in the field who knew the truth: the war on drugs has been and continues to be based on misinformation, religion and folly.
Religion enters in the 12 Step Program of Alcoholics Anonymous. It’s called a “higher power.” I have heard from people who have attended meetings in several cities and find many super focused on Christianity.
Alcoholism, then, became a sin to be dealt with the way other sins are dealt with, by a god. This is not specifically AA policy but many members think it is.
When other drugs, such as heroin, were outlawed that drug began to be associated with gutter life, hopeless addiction and hepatitis. When the drug is legal, most heroin users continue with successful careers and domestic life. For whatever reason, they need the drug and can use it harmlessly for years.
The link tells the story of a 1980’s doctor in Northern England who was tasked with writing legal heroin prescriptions. Because he could see the benefits of doctor-prescribed heroin, he expanded the program from two dozen to 400 patients. Addiction fell. There was a 93% drop in robberies as users did not need to rob. Drug dealers disappeared.
The U. S. pressured England and the program was stopped. All the former problems came back to that community.
Many of or our problems from drugs comes from the laws and moral views around them, not from the drugs.
