Yes, of course. It only makes sense. I would imagine that it's VERY difficult to get a non-cannabis user (or someone who has never used before) to begin using it as a medical treatment due to the stigma placed on the plant.
That said, I haven't consumed cannabis for a few years now and won't until I can obtain my medical card (soon, soon!).
But it's all a moot point because in my belief, all use is medical use.
