A certain type of incense is being used to get high.
K2 is a flavored incense that can be bought online or at some tobacco shops. The incense is laced with a chemical similar to marijuana. It's legal to buy, but some young people are smoking it to get high.
Some side effects of smoking K2 that have been reported include an elevated heart rate, mental health issues and even hospitalization.
Legislation has been proposed in several states around the country to ban the product.
