Let's be honest - 95% of people would take something, that was banned but which they thought would have no long-term negative health effects, if they thought the substance would result in them earning a couple extra million dollars.
There are tens of millions of people who take other drugs with far less benefits (just a good feeling) and far more penalties (fines, jail, health risks etc).
People get butthurt over this like they're children who just found out (SPOILER ALERT FOR SLATE!!!!) that Santa Clause isn't real.
