This drug is almost unheard of among the hip right now. Once illegal, it will be instantly popular and cool.
When all drugs were sold at drug stores, they weren't considered cool or counterculture. Addicts were simply sad sick people. It wasn't cool to take grandmas cocaine cough drops and it's still considered sad to chug cough syrup.
Once illegal, drugs attract rockstars, bikers, celebrities, drug lords and other glamorized people that are associated with excitement and beyond the mainstream.
A percentage of people always seek excitement and go against norms. Other people want to make money at all costs. Outlawing certain drugs gave both of those people many opportunities at a very high cost to us all.
More idiotic laws always equal more unintended consequences
I blame it all on Kitty Dukakis :)
