K2 incense was first created and distributed by Bouncing Bear Botanicals in 2009. It is a product slightly similar to Spice and comes in many varieties with names such as Blonde, Summit, Standard, Citron, Pink, and Blueberry. When it is smoked, effects usually last from 1-4 hours.
Side Effects and Adverse Reactions:
K2 contains synthetic cannabinoids that are research chemicals. Research chemicals are experimental chemicals that are not approved for human consumption. This is because not enough data exists currently about their side effects, adverse reactions, long term damage, addiction potential, etc. Although some people are willing to ingest research chemicals, it is not reasonable to assume that they are in any way safe to use recreationally.
K2 and Drug Tests:
JWH-018 can be detected with drug tests from the redwood toxicology laboratory. The test checks for JWH-018 and JWH-073 metabolites in the urine with a window of detection up to 72 hours (depending on usage/dosage).
