And whereas the Meals and Drug Administration has accredited cannabis-based merchandise for the therapy of cancer-related unwanted side effects, they aren’t confirmed to treatment most cancers.
USA TODAY reached out to the social media customers who shared the declare for remark.
Results solely proven in preclinical trials
Cannabinoids, chemical compounds within the hashish plant, have lengthy been demonstrated to kill most cancers cells in check tube experiments, based on Dr. Donald Abrams, an integrative oncologist on the College of California-San Francisco.
Nonetheless, these findings haven’t been replicated in scientific research involving people – the gold commonplace of medical analysis.
Dr. Christopher Holstege, chief of the division of toxicology on the College of Virginia, instructed USA TODAY he might discover no ongoing scientific trials of hashish as a therapy for most cancers in people. Research additionally do not sometimes use hashish in its uncooked kind, he stated.
“Researchers have a tendency to make use of extra purified merchandise versus uncooked plant materials partly as a result of they wish to know precisely what’s getting used within the research,” Holstege stated.

The earliest revealed analysis on the anticarcinogenic results of cannabinoids is a 1975 study that discovered the compounds inhibited lung adenocarcinoma most cancers cell development in vitro and in mice, based on a 2016 literature review. Preclinical research revealed in later years additionally discovered cannabinoids inhibited most cancers cell development for situations like breast cancer, melanoma skin cancer and thyroid cancer.
Some research have proven cannabinoids eradicate most cancers cells with out damaging wholesome ones, based on the National Cancer Institute. A 2021 study additionally discovered that extracts from the hashish plant defend regular colon cells whereas lowering the viability of cancerous cells.
These research are promising. However there may be nonetheless no “stable foundation for ongoing claims by proponents of extremely concentrated hashish extracts or oils that these preparations can ‘treatment most cancers,'” based on a 2015 literature review revealed within the journal Medical Pharmacology & Therapeutics. That is nonetheless true at the moment, Holstege stated.
Hashish is not a confirmed most cancers treatment
Whereas analysis has indicated some compounds in hashish can inhibit the expansion of cancerous cells, that does not imply it is a treatment. Most cancers sufferers who depend on hashish to deal with their situation can face potential well being dangers, based on Holstege.

Our score: Lacking context
Based mostly on our analysis, we price MISSING CONTEXT the declare that hashish kills most cancers cells. Preclinical research have proven that hashish compounds can kill most cancers cells, however no scientific trials in people have replicated these outcomes. Whereas some cannabis-based medication are accredited by the FDA to deal with cancer-related unwanted side effects, consultants warning that they aren’t an alternative choice to most cancers therapy. They may even have some opposed unwanted side effects.
