Two of my brothers were hardcore heroin addicts. One quit, the other died. As a matter of fact, off the top of my head, I could name a half a dozen people in my family circle who died from drug abuse. Even short of risk of death, I think getting high every day, whether from illegal drugs, prescription meds or alcohol, is way more trouble than it’s worth, and I have seen people I loved degenerate into something less than fully human after transmogrifying into junkies.
For these reasons, it is understandable why I don’t take lightly my adherence to the libertarian principle that people are inherently free to abuse themselves, but I do believe neither the state nor the citizenry have the right to forcibly prevent an individual from using drugs for recreational purposes.
