Everybody wants to know the answer to the big question….does cannabis kill cancer? There are a lot of positive testimonials on the internet and we know that THC can kill some types of cancer in petri dishes. Unfortunately, many drugs look great in cell cultures and animal models but fail in definitive clinical trials with humans.
In cell cultures and animal models, cannabis-derived cannabinoids, particularly THC and CBD, can have activity against some cancers but paradoxically can also accelerate the growth of others.
There are two early phase clinical trials published, one of which suggests it is possible cannabinoids might help treat a very aggressive type of brain cancer with few side effects. But it is irresponsible and harmful to say cannabis cures all types of cancer.
Research also shows alternative medicine use may delay conventional treatment, resulting in worse cancer-specific outcomes. However, given the proven benefits helping to treat cancer side effects such as loss of appetite, neuropathic pain, and nausea, cannabis is reasonable to use as an integrative treatment for those indications, but not in lieu of conventional therapy.
