Preclinical Evidence of Cannabis-Induced Oxidative Stress: Systematic Review & Meta-Analysis
| Journal | Regulatory toxicology and pharmacology: RTP |
| Study Type | Systematic Review |
| Population | Human participants |
This systematic review provides the first comprehensive analysis of cannabis-related oxidative stress, examining cellular damage markers across 51 studies. Understanding oxidative stress mechanisms helps inform clinical decision-making about cannabis safety profiles and potential protective strategies.
Researchers analyzed 9,775 records to identify 51 studies examining cannabis effects on oxidative stress markers in cell cultures and animal models. The meta-analysis of 49 studies found statistically significant but small increases in reactive oxygen species production in laboratory settings and more pronounced effects in animal studies, along with increased lipid peroxidation markers. The studies primarily used THC, CBD, or cannabis extracts across various delivery methods in over 1,200 animals, predominantly rats and mice.
“While these preclinical findings suggest oxidative stress potential, the clinical relevance remains unclear given the laboratory conditions and animal models used. I await human studies with real-world dosing and duration to guide patient counseling about oxidative stress risks.”

FAQ
What kind of research went into this oxidative stress review?
The researchers analyzed 9,775 records and identified 51 studies that examined cannabis effects on oxidative stress markers in cell cultures and animal models. The meta-analysis combined 49 of these studies. This is preclinical evidence, and the summary does not report any studies in human patients.
What did the meta-analysis find about cannabis and oxidative stress?
It found statistically significant but small increases in reactive oxygen species production in laboratory settings, with more pronounced effects in animal studies. The analysis also found increased lipid peroxidation markers. Both are among the oxidative stress markers the included studies examined.
Which cannabis compounds and animals were used in these studies?
The included studies primarily used THC, CBD or cannabis extracts, given by various delivery methods. The animal research involved more than 1,200 animals, predominantly rats and mice. The summary does not break down the results separately by compound or delivery method.
