The law is full of oppressive rules against everyday things that should really be legal in this day and age but somehow aren't -- say, driving without pants or time travel. At the same time, there are certain dubious acts that you're totally allowed to do this very moment, for one gobsmacking reason or another.
4 Pot Is Illegal in Most States, but Deadly Synthetic Marijuana Is A-OK in Colorado
In Colorado, all the kids are trying this new hot craze called dying in a hospital after smoking shitty synthetic marijuana -- or Spice for short. This bootleg pot (which is made in China) has been linked to three deaths, 150 hospital visits, and a presumed legion of embarrassing calls to poison control centers. Oh, and due to a loophole, it's totally legal.
The apparent problem is that this strange drug has no constant chemicals in it -- when the original chemicals were banned, they just started tossing in whatever shit could make you high, apparently. Because of that, teenagers can literally walk into stores and buy the stuff under the guise of it being "incense" or "potpourri."
"Hey guys, I had a brilliant idea- what if we made pot that could kill you?"
