Herbal Mixtures Harmful

K2, Hush and Swerve – herbal mixtures treated with chemical sprays that experts say can be twice as powerful as marijuana. The synthetic marijuana is legal in most parts of Texas and the United States. But alarmed by its growing use and easy availability, states and local governments are now scrambling to take "fake weed" off the streets.  Authorities say the fake weed appears easily accessible to teenagers. It can be bought in head shops and at gas stations – and also from anyone who can buy the chemical that is sprayed onto herbs to make the product.
