They most definitely do give cancer patients THC very commonly actually in the form of RSO
You are right, they do, because both are beneficial together. RSO, aka Rick Simpson Oil is a cannabis oil extract, just with higher amounts of THC (mostly to relieve pain and nausea) however, the CBD is the actual healing factor of the so called 'drug' (plant extract). RSO is an less pure form of distillate, which is what I choose to heal with.
