By MyFoxdc.com Video: http://goo.gl/ssTgt It's called Scooby Snax, but it's not a dog treat. Experts say it's synthetic marijuana, a dangerous drug kids are smoking. That's one of several types of fake marijuana FOX 5 found openly sold at gas stations and convenience stores, while federal and state bans have been hard to enforce. The products are labeled as potpourri but laced with chemicals that mimic the effects of pot. A quick search on YouTube and you see kids and young adults smoking it and getting high. "Scooby Snax is one of my favorites," proclaims one reviewer on YouTube. The federal government outlawed synthetic marijuana two years ago but Fox5 cameras didn't have a hard time finding Scooby Snax or a number of other products identified by experts as synthetic marijuana. There was dopey and bizzaro. Others go by names like Joker and the more commonly known K-2 and Spice. Duane Canter and his wife discovered their teenage son using it. &q
