AH-7921 is an opioid analgesic drug selective for the µ-opioid receptor, having around 80% the potency of morphine when administered orally.[1][2][3] It was discovered in the 1970s[4] by a team at Allen and Hanburys.

Use[edit]

Although AH-7921 was extensively studied in vitro and in animals, though not in humans, by the developing company, it was never sold commercially for medical use. In 2013, AH-7921 was discovered to have been used as an active ingredient in "synthetic cannabis" products in Japan.[5] In October 2015, two horses (Bossmon and Literata) trained by owner-trainer Roy Sedlacek tested positive for AH-7921 at Belmont Park racetrack.[6]

Legality[edit]

AH-7921 was made a Prohibited Substance (Schedule 9 of the Standard for the Uniform Scheduling of Medicines and Poisons) in Australia in May 2014.[7] Although this amendment was repealed in June 2014,[8] which simply means the amendment document ceases, but the actual scheduling is permanent as part of the main document (all SUSMP amendments cease after a few weeks). It may, however, still be a banned import.

AH-7921 has been illegal to distribute in Israel since December 2013.[9]

In the UK, AH-7921 was included as a Class A drug in January 2015 as part of The Misuse of Drugs Act 1971 (Amendment) (No. 2) Order 2014.[10]

In Brazil, AH-7921 has been an illegal drug since May 2015.[11]

As of October 2015 AH-7921 is a controlled substance in China.[12]

AH-7921 is banned in the Czech Republic.[13]

In the United States, AH-7921 was placed into Schedule I of the Controlled Substances Act on May 16, 2016.[14]

The Canadian Controlled Drugs and Substances Act was amended in 2016 to include the substance as a Schedule I substance. Possession without legal authority can result in maximum 7 years imprisonment. Further, Health Canada amended the Food and Drug Regulations in May, 2016 to classify AH-7921 as a restricted drug.[15] Only those with a law enforcement agency, person with an exemption permit or institutions with Minister's authorization may possess the drug in Canada.
