A new Spanish study suggests that the active ingredient in marijuana appears to reduce tumor growth.
The researchers showed giving THC to mice with cancer decreased tumor growth and killed cells off.
The findings add to mixed evidence that the drug can raise a person’s risk of heart attack or stroke and cause cancer, while other research shows benefits, such as staving off Alzheimer’s.
Guillermo Velasco of Complutense University in Madrid says, “Our findings support that safe, therapeutically efficacious doses of THC may be reached in cancer patients.”
The findings could help pave the way for cannabinoid-based drugs to treat cancer.
