The temporary rules for 2 June – as determined by the Oregon health authority (OHA) – permit dispensaries to sell one cannabinoid edible containing a maximum of 15mg THC (the principal psychoactive constituent of cannabis) per customer per day.
S-Nicotine, the principal psychoactive constituent of Nicotiana tabacum, underpins addiction to tobacco smoking.
Although THC is the most important psychoactive constituent of cannabis, there are other chemical compounds in marijuana that may impair driving safety.
Synthetic cannabinoids (SCBs) are a large family of molecules that are functionally similar to Δ9-tetrahydrocannabinol, the principal psychoactive constituent found in cannabis.
delta 9 -Tetrahydrocannabinol (Δ9-THC), the primary psychoactive constituent of marijuana, is subject to first pass hepatic metabolism primarily by hydelta 9 -Tetrahydrocannabinolnd inactive oxygenated products.
Δ9-Tetrahydrocannabinol is the primary psychoactive constituent, responsible, in a dose-related manner, for euphoria, cognitive effects, and psychotic symptoms, as well as the addictive potential of smoked cannabis due to its interference with the mesolimbic dopaminergic system.
The objective of this analysis was to determine whether the administration of Δ9-Tetrahydrocannabinol (THC), the principal psychoactive constituent of cannabis, impairs encoding and/or retrieval of verbal information.
It is well established that the main psychoactive constituent of cannabis, Δ9-tetrahydrocannabinol (THC), impairs episodic memory encoding and modulates emotional processing, but little is known about the impact of THC during the retrieval of emotional episodic memories.
The identification of the major psychoactive constituent of Cannabis and marijuana, Δ9-tetrahydrocannabinol, opened the way first to the cloning of the G-protein-coupled cannabinoid CB1 and CB2 receptors, and then to the isolation and characterisation of their endogenous agonists, the endocannabinoids.
Amanita muscaria is noted for its hallucinogenic properties, with its main psychoactive constituent being the compound muscimol.
