Herbal Incense

• Crushed, non-psychoactive herbal/plant matter treated with one or more synthetic cannabinoids

– First Generation: “K2”, “Spice”, “Black Mamba”, “Red Dragon”

– Second Generation: “K3”, “Splice”, “Apocalypse”, “Destiny”, “Cloud Ten”, “Head Trip”, house mixes

Current Legal Status of "first generation" Herbal Incense

• The federal Drug Enforcement Administration (DEA) has used its emergency scheduling authority to temporarily control five chemicals (JWH-018, JWH-073, JWH-200, CP-47,497, and cannabicyclohexanol) that were used to make “herbal incense” products

• Possessing/selling these synthetic substances or products in which they are contained now illegal for at least one year

• Over next year DEA and the United States Department of Health and Human Services (DHHS) will study whether these chemicals and products should be permanently controlled

Banned Herbal incense Brands

• Frequently marketed as “incense” under a variety of names:– K2– Spice/Spice Gold– Arctic Synergy– Black Mamba– Yucatan Fire– Red Dragon– Genie– Blaze– Red X – Dawn

Herbal incense Pharmacology

• To date, hundreds of synthetic cannabinoids (similar to both 9-THC and endogenous cannabinoids) have been created

• Potency ranges from hundreds of times more potent than THC to over 1000x less potent

• Most common psychoactive ingredient in herbal incense was JWH-018 (1-pentyl-3-[1-naphthoyl]indole)

• Synthesized in 1995 by Dr. John W. Huffman at Clemson University

DEA Analysis of “New Grass”

Herbal incense Pharmacology

• Research supported by NIDA

• Two cannabinoid receptors in the human brain, CB1 and CB2

• CB2 affects inflammatory pain and was the focus of NIDA study

• JWH-018 targets both receptors

• Huffman: “JWH-018 easiest to make outside a lab, requiring only two steps involving commercial products”

• Transferring the JWH to the botanical product involves using acetone

A Historical Perspective

• All drugs currently illicit in the U.S. have started out as legal (uncontrolled) substances– Heroin– Cocaine – Marijuana– MDMA (“ecstasy”)– LSD– Amphetamine

• Many of these “sat on the shelf” for years before becoming popular intoxicants

• A mixture of rumor, myth and science have all contributed to changes in the legal status of these substances

Herbal incense

• Street drugs– Psychoactive substances – Inconsistent ingredients– Unregulated manufacture– Multiple slang names– Often difficult to specify effects– Inflated prices

• Herbal incense has many of these characteristics

Drug Testing

• Many laboratories have a test for some of the first generation JWH chemicals

• In February, 2011 Redwood Laboratories announced a saliva based test that tests for JWH-018, JWH-073 and JWH-250

• Unknown if saliva/urine tests exist for the other cannabinoids in newer products

Herbal Incense in the Popular Press

• Sales of “K2” products increased significantly in Chicago following news of its impending status as a controlled substance

• Following an August 2008 report on “herbal incense” in Germany, ER visits ↑ significantly

• How do we inform the public of new drugs without setting of an epidemic of use?

Herbal Incense Pharmacology:The Scientific Literature

At present, almost nothing is known about the pharmacology, toxicology and safety profile of such compounds in humans*, except the opinions of consumers in internet forums.

Mustata, C; Torrens, M; Pardo, R; Perez, C; Farre, M. (2009).

• 3 individual “hits” from a small pipe• “organic” taste/no chemical odor or taste • 5 minutes: Feels like Cannabis• 10 minutes: Like an intense cannabis high• More than 3 puffs might be too much

Why the Discrepancy in Reported Effects?

• Use of other drugs (including alcohol) with herbal incense

• Varying potency

• “Hot spots”

• Overdose

• Presence of different cannabinoids

• “Knock-offs”

• User/environmental characteristics:

– Setting

– Set

Why the Discrepancy in Reported Effects?

• User/environmental characteristics:

– Set• Age

• Psychological stability

Overview

• Herbal incense contains a cannabinoid closely related to THC/marijuana

• No quality control• Manufacturing process may be associated

with adverse effects• Subjective effects most commonly

resemble those of extremely powerful marijuana

Overview

• Other reported effects range from intense euphoria and pleasant hallucinations to abject terror and near-psychotic reactions

• Almost complete lack of scientific study
