THC oil or Rick Simpson oil (RSO) is a great medicine. It can work against cancer, MS, Alzheimer's disease, diabetes, ALS, pain, insomnia, fears, psoriasis, epilepsy, rheumatism, ADHD, etc., etc. Cannabis contains a wide variety of active substances called maynabinoids. These are neurotransmitters that make body cells better communicate with each other. As a result, many physical conditions can improve or even disappear completely. The best known are THC and CBD. THC is the only one that has mind-glaring effects, so say where you can get stoned. This is also the reason for the witch hunt of governments against this plant.
