Today's youth has found a substitute to smoking cannabis and getting away with it. They are now smoking a drug called spice. Smokers of spice can get the same effects of smoking cannabis and without testing positive for drugs in their system. Spice can be found in many gas stations and head shops. Spice is a synthetic cannabis that can not be detected in the system as cannabis. Although many European countries have banned spice, it is still legal in the United States and Canada. Spice is sold as a herbal smoking blend or as incense. Spice is sold under the names of Spice and K2. Spice originated in Europe in 2004 and spread to the US and Canada. Spice has the same negative effects as marijuana and some users have an increased agitation and severe vomiting. Regular users of spice have noticed withdrawal symptoms. Some users of Spice have noticed ongoing psychotic episodes and is shown to produce psychosis in some of it's users. There are very little studies done on the effects synthetic cannabis has on the body. Most of the Spice users are teens and young adults. Keep an eye out for packages labeled Spice and K2. They are sold as incenses, but I would think twice if your teen says that is what they are using it for. It's better to be safe than sorry.
