(KMOV) -- A recent survey showed that nearly one in 9 high school seniors have gotten high in the past year on synthetic drugs.
The results come from the nations most comprehensive survey of teenage drug use, "Monitoring the Future."
The synthetic substances are often packaged and bought as potpurri or incense and sold in convenience stores. The drugs mimic the effects of marijuana.
Currently, the synthetic drugs are illegal in 40 states. Missouri and Illinois passed a state law in July 2010 to make synthetic drugs illegal. An Illinois law banning the sale or possession of these substances went into effect on January 1st, 2011.
Chicago Criminal Defense Lawyer Michael T. Norris, Ltd. and John W. Callahan, Ltd. provided this information to explain the Illinois law.
