In Japan the synthetic crap is used by a lot of people since pot is illegal. Whenever some traffic accident happens and it is discovered that synthetic poison is in the bloodstream of a driver, they dedicate days after days of news coverage reporting about the horrors that can result if you do such depravity. Of course, they never state that such crap exists mostly because possession of cannabis is verboten. Rather they just rave about how important it is to create new laws to regulate synthetics. In addition, they usually add that such terrible substances are flooding into the country because of the Chinese mafia and/or devils in North Korea. In the meantime, the real problem/cause - prohibition - is never addressed. Don't you just love Big State Government and Corporate Media?
