In your mind, probably not anymore than your comparing laziness to ingesting psychoactive substances of uncontrolled origin does to me. Peace.
We Libertarians want to decriminalize drugs so that the psychoactive substances you mention will be of CONTROLLED origin, the same way that tobacco and liquor products already are. Who do you sue if you buy a bad batch of drugs from a dealer? Answer: no one. Same question when they are regulated by the marketplace. Answer: the company (or pharmacy) that sold the drugs to you. Decriminalizing drugs will mean that they are REGULATED, because the marketplace is the most natural, organic and fairest kind of regulation there is. It provides (in most cases) almost immediate remedy for defective products or inferior services when government gets out of the way. Fear of competition not government bureaucrats is what keeps companies from giving us inferior products and services.
