I don’t know if a drug will cause someone to act like this. I don’t doubt that if we keep on the path with ‘designer’ drugs we will eventually get to the point where some recreational drugs can result in completely psychotic episodes.
Have you ever had to deal with someone on PCP? If not, let me tell you, when someone has a bad high on PCP, you are dealing with a temporary psychotic.
But that wasn’t the point of my argument. The point of my argument is that extreme ‘liberaltarians’ (those beyond libertarians who do believe in conserving our cultural mores) believe the government should not be restricting any drug usage, even something like ‘bath salts.’ I argue that as a culture and as a nation, we should do what we need to minimize the usage of hardcore substances that have such a destructive effect on its users that those users lose the ability or desire to provide for themselves and those they may have brought into this world and thus do very much impact others with their behavior by requiring others to pay to feed and house them.
Government restrictions on other drugs are what create a market niche for ‘designer’ drugs and ‘bath salts.’ If legal adult Joe Stoner could buy a joint where others buy their Jack, he'd have zero interest in messing with new, little-understood chemicals.
