Parkinson’s Disease and the THCV in cannabis.

New British and Spanish research on one of cannabis’ cannabinoids show its great potential for treating Parkinson’s disease. The cannabinoid is the lesser known but hugely interesting THCV, aka Delta-9-tetrahydrocannabivarin. The molecule is present to varying decrees in different strains of cannabis, from trace amounts to a hefty proportion.

Unlike your own body’s cannabinoid anandamide, or its phyto(plant based)-cannabinoid cousin, THC, THCV does not activate CB1 receptors in your endocannbinoid regulatory system. Activation of these CB1 receptors, found mainly on nerve cells, is responsible for most of THC’s psychoactive effects and medical benefits. THC also activates CB2 receptors, found more on immune cells and thought responsible for some of cannabis’ beneficial effects on some autoimmune disorders. Like THC, THCV also binds with and activates these CB2 receptors. Like THC, THCV is a powerful antioxidant, capable of sopping up cell-killing free radicals. Unlike THC, THCV does not activate CB1 receptors. Instead, it blocks (serves as an antagonist to) the activation of the CB1 system. It may play a major role in future treatments of cardiometabolic diseases and obesity.

The International Association of Cannabinoid Medicine reported the research as follows:

Parkinson’s disease
Spanish and British researchers investigated the effects of Delta-9-
tetrahydrocannabivarin (THCV) in an animal model of Parkinson’s
disease
. They concluded that “given its antioxidant properties and
its ability to activate CB2 but to block CB1 receptors, Delta-9-THCV
has a promising pharmacological profile for delaying disease
progression in PD and also for ameliorating parkinsonian symptoms.”

The fact that the research was British and Spanish, not American, is telling. Americans are not allowed to research cannabis and are denied access to marijuana for research. The pathetic paucity of medical cannabis research in the USA is a literal crime against humanity, a function of politics of prohibition. Americans by the millions suffer untreated pain, blinding glaucoma and immobilizing Parkinson’s disease while all research is denied, decade after decade. Instead of following a science-based assessment (which would demand a rush to research medical cannabis), American science has been held hostage to authoritarian bureaucrats.
