There are many different brands of herbal incense, and all of them are quite different.   Herbal incense, also known as spice or K2 is made from many different plants, including, damiana root,   Siberian motherwort, marshmallow honey, and molasses.  These herbs are then sprayed with a compound called JWH-018, which is a synthetic cannabinoid.  JWH-018 closely mimics the effects of THC, which is the main active ingredient in marijuana.  When herbal incenses are smoked, they are said to have a similar high to marijuana.   There are many individual brands of herbal incense including spice, K2, Mr. nice guy, cloud 10, stash, ix, and ixxx, and hundreds more.  Most brands of herbal incense do not label exactly how much of the compound exists in their product, so some could be more potent than others.  These products can be found in numerous places from the internet, gas stations, head shops, and truck stops.  Legalsmokeshop.com offers incense in many varieties and aromas.   Herbal incense is also more expensive than marijuana.  Marijuana has a street value of about 17 dollars a gram, and herbal incense averages about 25 dollars a gram.  As of right now herbal incense is legal, so people are willing to spend the extra money in order to get high.  All herbal incense that is sold come with warning labels that read –“not for human consumption”.  This is because they have not been tested by the FDA.  The herbal incense blends are still fairly new, so research is now being conducted on the effects for both short term and long term use.  Herbal incense is gaining popularity from people who have to pass drug tests. Most labs and screening centers don’t test for the synthetic chemicals found in herbal incense.   Therefore, people who use can smoke herbal incense as a way to get high, and pass a drug test.  There are currently no drug testing kits on the market for herbal incense.  Herbal incense varieties are being banned at a steady pace all over the United States, and they have already been banned in nine countries worldwide.
