Our take: Utah has had its own problems with "Spice," or synthetic marijuana, in the past, leading to a statewide ban on the substance. NPR reports on the difficulties of regulating this popular drug:
This week, President Obama signed a law banning synthetic marijuana and other synthetic drugs. Dozens of states and local governments have already tried to outlaw fake marijuana, which has been blamed for hundreds of emergency room visits and a handful of fatalities.
But the bans have proved largely ineffective, and there are fears that the federal law won't be any different.
