Police and health leaders are spreading the word about a synthetic drug they say has killed at least two Indiana teenagers this year. It's called N-Bomb. It mimics LSD. Dealers purchase it over the Internet and teens spread the word about it by talking and texting. The Drug Enforcement Administration says dealers buy N-Bomb from China, put it on blotter paper and sell it to young people who don't know how dangerous it can be. It's been blamed for more than 20 deaths since March 2012.
