St. Louis, Missouri – Yesterday Missouri became the fifth state to ban the marijuana-like substance known as "K2".
The penalties for possession will be similar to regular pot.
K2 is a mixture of dried herbs sprayed with a synthetic substance that, when smoked, mirrors the effects of cannabis.
Governor Jay Nixon says the popularity of K2 has spiked in recent months among college and high school students, making it a legitimate health risk.
