Hexahydrocannabiphorol (HHCP, sometimes mistakenly referred to as hexahydroxycannabiphorol) is a semi-synthetic cannabinoid derivative which has been marketed since around 2021. [1] [2] It is believed to be made from the hydrogenation of tetrahydrocannabiphorol (THCP). THCP is only reported as a trace component of cannabis in 2019. [3] HHCP was studied by Roger Adams as early as 1942. [4]

Legality

The legal status of hexahydrocannabinol and derivatives varies between countries, leading to widespread sale in some jurisdictions in Europe and the US.

In France, HHCP was banned in 2023. [5]

In Japan, Japanese Health Ministry announced that six synthetic cannabinoids with structures similar to HHCH, including HHCP, were to be banned from 6 January 2024. [6]

HHCP was banned in Slovakia as of 13 January 2024.[ citation needed ]

<span class="mw-page-title-main">Cannabinoid</span> Compounds found in cannabis

Cannabinoids are several structural classes of compounds found in the cannabis plant primarily and most animal organisms or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea.

THC-O-acetate is the acetate ester of THC. The term THC-O-acetate and its variations are commonly used for two types of the substance, dependent on which cannabinoid it is synthesized from. The difference between Δ8-THC and Δ9-THC is bond placement on the cyclohexene ring.

Dimethylheptylpyran is a synthetic analog of THC, which was invented in 1949 during attempts to elucidate the structure of Δ9-THC, one of the active components of Cannabis. DMHP is a pale yellow, viscous oil which is insoluble in water but dissolves in alcohol or non-polar solvents.

<span class="mw-page-title-main">JWH-018</span> Chemical compound

JWH-018 (1-pentyl-3-(1-naphthoyl)indole, NA-PIMO or AM-678) is an analgesic chemical from the naphthoylindole family that acts as a full agonist at both the CB1 and CB2 cannabinoid receptors, with some selectivity for CB2. It produces effects in animals similar to those of tetrahydrocannabinol (THC), a cannabinoid naturally present in cannabis, leading to its use in synthetic cannabis products that in some countries are sold legally as "incense blends".

<span class="mw-page-title-main">Synthetic cannabinoids</span> Designer drugs

Synthetic cannabinoids are a class of designer drug molecules that bind to the same receptors to which cannabinoids in cannabis plants attach. These novel psychoactive substances should not be confused with synthetic phytocannabinoids or synthetic endocannabinoids from which they are in many aspects distinct.

<span class="mw-page-title-main">APINACA</span> Chemical compound

APINACA (AKB48, N-(1-adamantyl)-1-pentyl-1H-indazole-3-carboxamide) is a drug that acts as a reasonably potent agonist for the cannabinoid receptors. It is a full agonist at CB1 with an EC50 of 142 nM and Ki of 3.24 nM (compared to the Ki of Δ9-THC at 28.35 nM and JWH-018 at 9.62 nM), while at CB2 it acts as a partial agonist with an EC50 of 141 nM and Ki of 1.68 nM (compared to the Ki of Δ9-THC at 37.82 nM and JWH-018 at 8.55 nM). Its pharmacological characterization has also been reported in a discontinued patent application. It had never previously been reported in the scientific or patent literature, and was first identified by laboratories in Japan in March 2012 as an ingredient in synthetic cannabis smoking blends, along with a related compound APICA. Structurally, it closely resembles cannabinoid compounds from a University of Connecticut patent, but with a simple pentyl chain on the indazole 1-position, and APINACA falls within the claims of this patent despite not being disclosed as an example.

5F-AMB (also known as 5F-MMB-PINACA and 5F-AMB-PINACA) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family, which has been used as an active ingredient in synthetic cannabis products. It was first identified in Japan in early 2014. Although only very little pharmacological information about 5F-AMB itself exists, its 4-cyanobutyl analogue (instead of 5-fluoropentyl) has been reported to be a potent agonist for the CB1 receptor (KI = 0.7 nM).

<span class="mw-page-title-main">Tetrahydrocannabiphorol</span> Cannabinoid agonist compound

Tetrahydrocannabiphorol (THCP) is a potent phytocannabinoid, a CB1 and CB2 agonist which was known as a synthetic homologue of THC, but for the first time in 2019 was isolated as a natural product in trace amounts from Cannabis sativa. It is structurally similar to Δ9-THC, the main active component of cannabis, but with the pentyl side chain extended to heptyl. Since it has a longer side chain, its cannabinoid effects are "far higher than Δ9-THC itself." Tetrahydrocannabiphorol has a reported binding affinity of 1.2 nM at CB1, approximately 33 times that of Δ9-THC (40 nM at CB1).

<span class="mw-page-title-main">Δ-10-Tetrahydrocannabinol</span> Isomer of tetrahydrocannabinol

Δ-10-Tetrahydrocannabinol is a positional isomer of tetrahydrocannabinol, discovered in the 1980s. Two enantiomers have been reported in the literature, with the 9-methyl group in either the (R) or (S) conformation; of these, the (R) enantiomer appears to be the more active isomer as well as the double bond in the 10th position instead of the 9th maintaining about 30 to 40 percent the potency of delta-9-THC. Δ10-THC has rarely been reported as a trace component of natural cannabis, though it is thought to be a degradation product similar to cannabinol rather than being produced by the plant directly. However, it is found more commonly as an impurity in synthetic delta-8-THC produced from cannabidiol and can also be synthesized directly from delta-9-THC.

Hexahydrocannabinol (HHC) is a hydrogenated derivative of tetrahydrocannabinol (THC). It is a naturally occurring phytocannabinoid that has rarely been identified as a trace component in Cannabis sativa, but can also be produced synthetically by hydrogenation of cannabis extracts. The synthesis and bioactivity of HHC was first reported in 1940 by Roger Adams using tetrahydrocannabinol prepared from cannabidiol.
