Marijuana’s potential in neurodegenerative diseases: an editorial

Summary & key facts

This editorial reviews research on marijuana and its main compounds, THC and CBD, as possible tools to help with neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and ALS. It says cannabinoids can show anti-inflammatory, antioxidant, anti-excitotoxic, and other neuroprotective effects in studies. The paper stresses there is growing interest but also that clear, proven treatments to stop these diseases are still lacking and more research is needed.

Key facts:

• The editorial focuses on neurodegenerative diseases named in the paper: Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS).
• Marijuana contains many chemical compounds; the two primary ones discussed are tetrahydrocannabinol (THC) and cannabidiol (CBD).
• THC is described as psychoactive and can cause effects such as hypolocomotion, hypothermia, catalepsy, and analgesia. It is also reported to have neuroprotective, antispasmodic, and anti-inflammatory actions mediated in part by receptors in
• CBD does not have the psychoactive effects of THC and is increasingly of interest for potential medical benefits in neurodegenerative research.
• The editorial reports that emerging evidence suggests cannabinoids may produce anti-inflammatory, antioxidant, and anti-excitotoxic effects that could be neuroprotective.
• The authors note other cannabinoids and terpenes in marijuana can influence its pharmacological profile, so the plant’s exact composition matters for potential effects.
• The piece emphasizes that, despite these findings and growing interest, effective treatments that can halt or reverse neurodegenerative disease progression remain elusive and require more study.

Abstract

Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS), represent a significant global health challenge.These conditions are characterized by the progressive deterioration of neurons in the central nervous system, leading to debilitating symptoms and a decline in cognitive and motor functions.Despite extensive research, effective treatments that can halt or reverse disease progression remain elusive.In recent years, there has been increasing interest in exploring the potential role of marijuana in the management and treatment of neurodegenerative diseases [1].Inspired by the Special Issue, "Special Edition on Marijuana" of AIMS Neuroscience, we would like to provide a thoughtful perspective on marijuana's potential and its implications in the field of neurodegenerative research.Marijuana is a plant that contains numerous chemical compounds, with two primary constituents gaining significant attention: tetrahydrocannabinol (THC) and cannabidiol (CBD).THC is known for its psychoactive properties such as hypolocomotion, hypothermia, catalepsy, and analgesia.On the other hand, THC has neuroprotective, antispasmodic, and anti-inflammatory actions, which are mediated through the activation of different receptors, such as CB2 and PPAR [2,9].Until recently, most of the interest in medical uses of marijuana was focused on the actions of THC, but now there is growing interest in potential medical uses of CBD, which does not have the psychoactive effects of THC and appears to have a number of therapeutic benefits.Other cannabinoids and terpenes present in marijuana contribute to its diverse pharmacological profile, potentially influencing its effectiveness in neurodegenerative diseases.Understanding the composition and interactions of these compounds is crucial in assessing marijuana's therapeutic potential [2].Interestingly, emerging evidence suggests that marijuana and its constituents possess neuroprotective properties.Cannabinoids, through their interaction with the endocannabinoid system, have demonstrated anti-inflammatory, antioxidant, and anti-excitotoxic effects, which may help
