'Synthetic marijuana' banned in Missouri
By AP/St. Louis Public Radio
Jefferson City, MO – On Tuesday Missouri becomes the latest state to criminalize synthetic marijuana.
The fake pot, often branded as K-2, is sold at head shops and convenience stores.
It's made up of dried herbs and flowers sprayed with a chemical that some users say mimics the effects of cannabis.
The fake marijuana is already illegal in much of Europe, and in the last year many American cities banned it.
Now Missouri is joining Kansas and North Dakota in making the sale or possession of synthetic marijuana illegal on the state level. Many other states are considering similar laws.
Fake pot emerged in the middle of the last decade. Entrepreneurs copied a chemical formula published by a university chemist who was researching cannabinoids.
