Did you heard about the Rick simpson's oil ? It seems that it is the most appropriate for healing, cancer treatment etc.. It has a very high THC level, like 50, 60% and a low CDB level, around 10, 15%.
A friend of mine was using oil to cure cancer, but like you he couldn't stand the CDB oil. He tried Rick's one, got no more discomfort and cure his kidney cancer in 5 months.
