Im pretty sure bob marley died of toe cancer, but marley loved his joints… he would smoke pounds of joints. The problem with smoking weed is that it contains slightly cancerous compounds in the leaves, which is extracted when you make hemp oil. Also paper, and butane are also cancerous, and to top it off when you smoke weed you lose 95% of it healing properties as well. So he was filling his body with slight poisons and he was only delivering 5% of the healing properties to his body… so he was not filling his cells with pure THC and CBD. I doubt the benefits of hemp oil were even discovered yet either… he died around 1980.
CBD is an oil in the plant that promotes healthy cell reproduction.. our cells are always reproducing, and in cancer they reproduce cancerous cells. But CBD allows the body to create healthy ones which is a huge part of the healing process.
