The Nixon administration systematically-destroyed the commissioned-study by the Medical College of Virginia that showed Delta-9-THC killed many cancerous cell-types, both benign and malignant. From that study:
“Delta-9-THC, delta-8-THC, and cannabinol (CBN) all inhibited primary Lewis lung tumor growth, whereas cannabidiol (CBD) enhanced tumor growth. Oral administration of 25, 50, or 100 mg delta-9-THC/kg inhibited primary tumor growth 8, 72, and 75 percent respectively, when measured 12 days post tumor inoculation. On day 19, mice given delta-9-THC had a 34 percent reduction in primary tumor size. On day 30, primary tumor size of 76 percent that of controls and only those given 100 mg delta-9-THC/kg had a significant increase in survival time (36 percent).”
In Feburary 2000, Dr. Manuel Guzman, et. al., of Complutense University found that THC killed 'incurable' brain tumors --emphasis added, as they're not as 'incurable' as once thought. The main findings:
“Delta-9 THC, the main active component of marijuana, induces apoptosis of transformed neural cells in culture. Here, we show that intratumoral administration of delta-9-THC and the synthetic cannabinoid agonist WIN-55,212-2 induced a considerable regression of malignant gliomas in Wistar rats and in mice deficient in recombination activating gene 2. Cannabinoid treatment did not produce any substantial neurotoxic effect in the conditions used. Experiments with two subclones of C6 glioma cells in culture showed that cannabinoids signal apoptosis by a pathway involving cannabinoid receptors, sustained ceramide accumulation and Raf1/extracellular signal-regulated kinase activation. These results may provide the basis for a new therapeutic approach for the treatment of malignant gliomas.”

Apoptosis is the key word here. Everyone has cancerous cells most of the time in their life, yet our immune system should be capable of taking care of the problem. The main problem is that too many people are fat, sick, and tired from too many toxic 'hits' from the environment, e.g., pollution, off-gassing from the many plastics in our house and car, like carpet and dashboards. Not to mention that you can't have clean food without clean water and air...
It's been shown that The Gerson Therapy (Max and Emily, his daughter) can give your immune system that boost it needs to put cancer back in remission --remission is a weird word, as a healthy person is constantly in remission, as their immune system is working properly. These mainly-raw food diets have also been shown to reverse Type-2 diabetes, as well as help Type-1 diabetics use up to 60% less insulin.
Let's not forget about stem cells. They can do soooo much if only we could get over the concept that 'viable stem cells' need to come from fetal-only sources. A clinic in Broomfield, Colorado was having amazing results with cloning individuals' adult stem cells and injecting them, directly, to sites that were damaged; like torn tendon and ligament. In post-Jesus Bush's world, stem cells get the short shaft because of religious fundamentalism while researchers in Europe, China, etc. get to have all the fun.
So, why the hell is CRISPR getting human trials before mice, chimps, etc?? It's an amazing piece of technology that was bound to come along, but it's potential for abuse is probably being studied as I write this... The Pentagon wants super-soldiers that can heal like Wolverine/Deadpool, y'know. We all know what trouble that led to the crew of the Enterprise... KAHN!!!!!!
And, I can't help but remember that Star Trek:TNG episode where the researchers discovered that they were being sickened by the genetically-enhanced children, of whom they modified their immune system to perform at peak-operating level.
So, to cap it off, THC is good, m'kay..? Technology isn't bad, but the ethics of its use need to be properly discussed.
