Delta-8-THCM (O-Methyl-ÃÂ<sup>8</sup>-THC) is a chemical compound related to phytocannabinoids found in Cannabis. It has been sold as a designer drug, first identified in Sweden in June 2024. However, it is a known compound which has been well established to almost entirely lack cannabinoid-like effects in mice, rats and monkeys, unlike the dimethylheptyl analogue L-759,633 which is a selective agonist for CB<sub>2</sub> and has antiinflammatory but not psychoactive effects.
