Need medical marijuana but not through smoking

Heyy!!
When I was 19 I smoked for the first time. Because I was curious to know what it is as my buddies were smoking every time. Some of my pals were chain smokers and they used to smoke at least 5 packs per day. I had a roommate who used to smoke continuously and my room is filled with full of smoke, right now I hate its smell. I have noticed some changes in me these days. I have difficulty in moving arms and legs, sometimes unsteady gait and trouble in walking. I just a took a visit to a nearby clinic and the doctor over there diagnosed multiple sclerosis in me. The clinic was providing medical marijuana treatment and he suggested medical marijuana treatment for multiple sclerosis ( http://apollocannabis.ca/chronic-pain/multiple-sclerosis/ ) . I started my research on medical marijuana.
Recently when I went through a blog I read about the best ways to consume marijuana. I read about the different methods such as the joints, edibles, tinctures, pills, vaporizers, or by smoking. Each of them has their own merits and demerits. I don’t want to try smoking anymore. Can someone share among these which one is the best method for me?
