Here in my fair state of New York, the new medical cannabis program came into effect at the beginning of the year. One of the unique characteristics of the program is that no smoking is allowed (vaping will soon be available though). The primary means of delivery is via a tincture. The kit comes with a 1ml syringe (no needle) to extract the oil. You then squirt the contents under the tongue and try not to swallow for a while.
I currently use a 1:1 ratio of THC/CBD for pouchitis. And no, I don't get high - not even a little. However, you can obtain tinctures with a much higher THC/CBD ratio which will almost certainly have psychoactive effects. The trick is finding the appropriate dose/ratio that works best for your specific complaint.
So far so good for me. I haven't used antibiotics for the past month and feel quite good. But this is still new and I will need more time to come to any conclusions about its efficacy for my particular situation. Having spent a good deal of time studying medical cannabis, I am quite hopeful. I am also stupefied that cannabis remains a schedule I drug. A little background can be found here.
One possible option that should be available to Canadians is Charlotte's Web from CW Botanicals. This is a CBD based product sold as a hemp extract and dietary supplement and thus not subject to cannabis laws. It is also the same product that came to medical cannabis fame for being an effective treatment for epilepsy. I actually started using this prior to obtaining my current medical cannabis prescription. It seemed to be helpful for my pouchitis as well. I don't know if it is effective for pain (I was under the impression THC was better for that), but may be worth a try.
Hope this is helpful.
