Common herbal incense blends are Mr. Nice Guy, K2 ( K-2 , K2 sky , k2 summit , k2 incense ) , Barely Legal , Flame incense blends, Oasis, and Spice. These herbal blends is widely known as "Spice" even though that is just one of the brands.
Original incense herbal like Mr Nice Guy, some of the older blends of K 2 incense, and Oasis are now banned because of their chemical makeup. The ban only made 5 chemicals illegal, most importantly JWH-018 ( the main chemical in incense blends like K2 Summit, Spice, K2 Blonde, etc), but JWH-081, JWH-019, JWH-073, HU-211, JWH-200, HU-210, CP47, 497 and cannibicyclohexanol, stimulant BZP and TFMPP are also banned in many areas, so check your area first to find out which products are banned! The ban will be for 1 year to allow time for testing, but now there are safer, better chemicals out there which are being used in the new blends.
