In a study that confirms what you totally already knew, it turns out that the active ingredient in ganja kills off brain cancer cells:
In the study, THC was found to induce the death of various human brain cancer cell lines and primary cultured human brain cancer cells by a process known as autophagy...
As analysis of tumors from two patients with recurrent glioblastoma multiforme (a highly aggressive brain tumor) receiving intracranial THC administration showed signs of autophagy, the authors suggest that cannabinoid administration may provide a new approach to targeting human cancers.
It's like you can just feel it working, like the smoke is little soldiers going in and like grabbing the brain cancer and throwing it down a deep black hole and you exhale it out with the smoke and inhale purification and like, cleanse. Dude.
