Herbal Incense which is being called ‘Synthetic cannabis’ is a blend of herbs and chemical products that, when mixed together can give the same effects as cannabis (marijuana). Herbal Incense contains what is called JWH-018 which is the main ingredient in making cannabis and other drugs that can make a person feel ‘high’. Many tests have been made on Herbal Incense in order to figure out its effects on the body and what dangers these spices can have on the human body.Initial researches and tests on Herbal Incense could not identify any illegal substances and any substance that is responsible in causing the high. Many hospitals started to report instances where a person appeared to have all the symptoms of cannabis intoxication, but their drug screen was negative. However; Herbal Incense has never been tested on humans. In fact what tests could show is that even the same brand of one product may have different drugs, in different amounts, at different times. Tests also showed that these spices can be very addictive.
