Hi D, I'm pleased for you, I wish you all the very best with it. Some states here agreed to participate in trials but it is unlikely ever to be approved for chronic pain. MJ is an S9 here, oxy is an S8.

THC supposedly gives euphoria, pain relief and increases the appetite, CBD will only deal with the pain. From what I can glean the pill format seems to be THC.

Cannabis vaporizers gained popularity because of peple declining to smoke it and the dose is unpredictable. Cannabinoid medicines are available in pill form in the US apparently, (dronabinol and nabilone) and liquid extracts formulated into an oromucosal spray (nabixinols)
