Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

211
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

Hallucinogens and Psychedelics01:27

Hallucinogens and Psychedelics

162
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

Color Vision01:24

Color Vision

553
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Taste Buds and Receptors01:20

Taste Buds and Receptors

1.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Area of Science:

  • Neurology
  • Ophthalmology
  • Pharmacology

Background:

  • Visual snow syndrome (VSS) is a rare condition characterized by persistent, low-level visual static.
  • The etiology of secondary VSS is not fully understood, but substance use has been implicated.

Purpose of the Study:

  • To report a case of VSS following the ingestion of a delta-8 tetrahydrocannabinol (THC) gummy.
  • To discuss the potential link between delta-8 THC and secondary VSS, as well as hallucinogen-persisting perception disorder (HPPD).

Main Methods:

  • A case report of a 26-year-old male patient presenting with VSS.
  • Review of literature concerning VSS, secondary VSS, HPPD, and delta-8 THC.
  • Clinical evaluation of the patient's symptoms and potential triggers.

Main Results:

  • The patient developed VSS after consuming an estimated 4 mg of delta-8 THC from a gummy.
  • The patient's symptoms are consistent with VSS, and the temporal association with delta-8 THC ingestion suggests a causal link.
  • Discussion of the potential for delta-8 THC to induce or exacerbate VSS and HPPD.

Conclusions:

  • Delta-8 THC consumption should be considered as a potential cause of secondary VSS.
  • Clinicians evaluating patients with visual disturbances, particularly VSS, should inquire about the use of delta-8 THC products.
  • Further research is warranted to elucidate the neurobiological mechanisms underlying delta-8 THC-induced VSS and HPPD.
