Cannabinoids in health and disease

Area of Science:

• Pharmacology
• Neuroscience
• Medical Chemistry

Background:

• Cannabis sativa L. preparations have a long history of medicinal use, interrupted by prohibition in the 1930s due to abuse concerns.
• Recent resurgence in interest acknowledges the therapeutic value of marijuana, cannabinoids, and related compounds, though their mechanisms are not fully understood.

Observation:

• Cannabinoids demonstrate potential in treating a wide array of conditions including pain, inflammation, neurodegenerative disorders, epilepsy, and more.
• Despite mild addiction risks and potential for enhancing other substance abuse, the therapeutic benefits are substantial.
• The low toxicity and generally benign side effect profile of cannabinoids support their clinical consideration.

Findings:

• Cannabinoids are being investigated for treating conditions such as anorexia, emesis, pain, inflammation, multiple sclerosis, Parkinson's disease, Huntington's disease, Tourette's syndrome, Alzheimer's disease, epilepsy, glaucoma, osteoporosis, schizophrenia, cardiovascular disorders, cancer, obesity, and metabolic syndrome.
• The therapeutic value of cannabinoids is considered too significant to ignore, even with potential addiction concerns.

Implications:

• Neglecting the clinical potential of cannabinoids is unacceptable due to their low toxicity and broad therapeutic applications.
• Development of more selective cannabinoid receptor agonists/antagonists and related compounds is necessary.
• Future research should focus on novel drugs with improved selectivity, distribution, and pharmacokinetics, and careful monitoring of psychoactivity where inseparable from therapeutic effects.
