Notice of Intent – 3 More Synthetic Cannabinoids into Schedule I

Today, December 19, 2014, the United States Drug Enforcement Administration (DEA) filed a notice of intent for placement of three new synthetic cannabinoids into Schedule I of the Controlled Substance Act (CSA).

These three substances are:
AB-CHMINACA, AB-PINACA, and THJ-2201
All three of the substances have been discussed at one time or another here on TDMTP and are suspected to be CB1/CB2 receptor agonists, but true pharmacological and toxicological evidence does not exist.


 
AB-PINACA is N-(1-amino-3-methyl-1-oxyobutan-2-yl)-1-pentyl-1H-indazole-3-carboxamide. The “alphabet soup” name seems to reside in the following generic name: AminomethloxoButanePentylINdAzoleCarboxAmide. This synthetic cannabinoid was first encountered in March 2013 (reported by the National Forensic Laboratory Information System or NFLIS) and June 2013 (reported by the System to Retrieve Information from Drug Evidence or STRIDE). States reporting detection of this substance in products include AL, AR, AZ, CA, CO, CT, FL, GA, IA, ID, IL, IN, KS, KY, LA, MA, MI, MN, MO, MS, ND, NE, NH, NJ, NV, NY, OH, OK, OR, PA, SC, TN, TX, UT, VA, WA, WI, WV, and WY. From March 2013 to September 2014, there were 4 seizures of this compound (6 kg). Adverse effects from using the substance (as well as AB-CHMINACA discussed below) were seizures and convulsions, unconsciousness and coma, agitation, motor function loss, and respiratory issues. The DEA also reports that there have been at least 3 documented deaths involving AB-PINACA.
Some literature references for AB-PINACA:

AB-CHMINACA is N-(1-amino-3-methyl-1-oxobutan-2-yl)-1-(cyclohexylmethyl)-1H-indazole-3-carboxamide.  The “alphabet soup” name seems to reside in the following generic name: AminomethloxoButaneCycloHexylMethylINdAzoleCarboxAmide. This synthetic cannabinoid was first encountered in February 2014 (NFLIS) and March 2014 (STRIDE). States reporting detection of this substance in products include AR, AZ, CA, CO, GA, IA, IN, KS, KY, LA, MO, ND, NJ, OH, OK, PA, TN, TX, and WI. From February 2014 to September 2014, there were 17 seizures of this compound (15.825 kg). The DEA also reports that there have been at least 4 documented deaths involving AB-CHMINACA.
A literature reference for AB-CHMINACA:
Hasegawa et al. (2014) Postmortem distribution of AB-CHMINACA, 5-fluoro-AMB, and diphenidine in body fluids and solid tissues in a fatal poisoning case: usefulness of adipose tissue for detection of the drugs in unchanged forms. Forensic Toxicology, Article in Press, doi: 10.1007/s11419-014-0245-6
THJ-2201 is [1-(5-fluoropentyl)-1H-indazol-3-yl)naphthalene-1-yl)methanone. This synthetic cannabinoid was first encountered in September 2013 (STRIDE) and January 2014 (NFLIS). States reporting detection of this substance in products include AR, AZ, CT, GA, IA, IL, IN, KS, KY, MN, MO, ND, NE, NH, NJ, OH, PA, TN, and WI. From September 2013 to September 2014 there were 6 seizures of this compound (5.5 kg). The DEA did not report any information on deaths associated with this compound.
A literature reference for THJ-2201:
Shevyrin et al. (2014) 3-Naphthoylindazoles and 2-naphthoylbenzoimidazoles as novel chemical groups of synthetic cannabinoids: chemical structure elucidation, analytical characterists and identification of the first representatives in smoke mixtures. Forensic Science International, 242, 72-80. PMID 25036783.
So, now after legislation and a few rounds of emergency scheduling, there are 25 synthetic cannabinoid compounds explicitly listed as federally controlled Schedule I substances:
AM2201, AM694, CP-47,497, CP-47,497 (C8), JWH-018/AM678, JWH-019,JWH-073, JWH-081, JWH-122, JWH-200, JWH-203, JWH-250, JWH-398, RCS-4/SR-19,RCS-8/SR-18
AKB48, UR144, XLR11
5F-PB-22, AB-FUBINACA, ADB-PINACA, PB-22

AB-CHMINACA, AB-PINACA, THJ-2201
 
Wonder what will be next? Maybe the AMB series? We’ll see. As always, the beat goes on.

  1. The United States Drug Enforcement Administration (DEA) has noticed this right. I have also heard of that before from a medical scientist. Thanks for sharing this with us. Now it's time to avail airport chauffeur service for more information.
