Synopsis

  • Delta(9)-tetrahydrocannabinol (THC) is the main psychoactive constituent of the Cannabis sativa L (Marijuana) plant.
  • Others marijuana-derived cannabinoids includes Cannabichromene (CBC), Cannabidiol (CBD), Cannabinol (CBN), Cannabigerol (CBG), and Tetrahydrocannabivarin (THCV).
  • Marijuana-derived cannabinoids are known as phytocannabinoids.
  • THCA is the biosynthetic precursor of THC.

Antidepressant properties of THC

  • THC may stimulate anandamide mobilization(?) by binding to the CB1 receptor, thus producing a antidepressant and neuroprotective effect. [1]

Neuroprotective properties of THC

Alzheimer

  • THC may inhibit acetylcholinesterase-induced intraneuronal amyloid beta aggregation in Alzheimer's disease. [2]
  • THC may prevent intracellular amyloid beta proteotoxicity and inflammatory response. [3]

Drug-induced dopamine supersensitivity

  • THC is high-affinity dopamine agonist for reversing drug-induced dopamine supersensitivity. [4]

Cognitive aging

  • THC may reverse the cognitive aging process in the brain. (Reference needed)

Glaucoma

  • THC may reduce intraocular pressure (IOP) in retinal ganglion cells (RGCs) through intracellular CB1 receptor activation.
    • A potential treatment for glaucoma to prevent optic nerve damage.

Tardive diskinesia

Traumatic brain injury

Posttraumatic stress disorder

  • THC may reduce chronic nightmares frequency and alter dreaming activity?

Sleep regulation

  • THC may affect REM-sleep rebound. [5]
  • THC may reduce REM-sleep and increase slow wave sleep (SWS).

Effects of THC on neurogenesis, synaptogenesis and BDNF signaling

  • Hippocampal CB1 receptors regulate stress-induced neuroinflammation in the hippocampus. [6]
  • THC enhance adult hippocampal neurogenesis and BDNF signaling through intracellular CB1 receptor activation. [7][8]
  • Intracellular CB1 activation promote neuronal cell proliferation, differentiation, maturation, and neurite growth. [9]

Neuropsychology of THC tolerance

  • CB1 receptor sensitization can be restored by taking breaks of oral THC administration. (Reference needed)
  • Alcohol increase THC levels in blood. (Reference needed)
  • THC tolerance is genetic and regulated by the AKT1 gene.

Notes

  • THC may increase serotonergic tone. [10]
  • Possible cross-talk between dopaminergic vitamin D, delta9-THC, and endogenous cannabinoids (anandamide) ?

Experimental

  • Endogenous retrograde trafficking may promote hippocampal development (neurogenesis) and synaptogenesis.
  • Arachidonic acid/DHA levels affect neural stem/progenitor cells (NSPCs) proliferation in the hippocampus. (Reference needed)
  • THC may enhance corticostriatal functional connectivity though increased c-Fos expression. [11]
  • Long-term THC administration may depletes melatonin synthesis.
