These are substances that can cause lifelong health problems and lead to death, yet they are widely available, often sold in corner stores or gas stations. Many people, including retailers, parents and teens, don't know how dangerous they are. Popularly known as K2, "spice" or "bath salts," these substances are marketed as "safe" alternatives to illicit drugs. Actually, they are just as dangerous because they contain untested chemical compounds that have devastating consequences for users. Many are misleadingly marketed as room fresheners, herbal incense or potpourri, but they are not household products at all; they are man-made chemicals sprayed on dried plants. Scientists have called these substances Russian Roulette; you never know what you will get, and it will likely harm or kill you.
