Police in Des Moines are taking a new tack in the battle to stop the sale of synthetic marijuana.
The Des Moines Register reports that instead of trying to prove the illegality of ingredients used to make the synthetic pot, they're now going after the packaging and marketing of the drug.
Officials have tried for four years to get synthetic drugs off the market by passing laws banning specific chemical compounds that mimic the effects of marijuana. Manufacturers of the drug have stayed one step ahead, tweaking formulas just enough to be legal.
Now, officials hope they can stop the drug by taking action against any substance - no matter what's in it - that is presented to potential buyers as a way to get high.
