Have you tried micro-dosing? Low-dose edibles?
The absolute best day time medical use I've personally had was a box of 10mg hard candies a friend brought me from Colorado a while back. I'd eat half of one and the other half about mid-day. I'd get a very slight head-change from it, but as for calm and reduced pain, amazing. On a bad pain day I'd eat a whole one which you can feel a bit more but leaves you, or at least left me, clear enough to function.
I can't get anything here in the icy wastes so I've been trying to moderate day use with a one hitter lightly packed as needed. Not as good for managing the high but still with in reason.
From the little experience I have with quality edibles, my impression is I like them much more as a day time controlled therapeutic, but for kicking back in the evening or if I'm wanting a "recreational" high it's smoking hands down for me,
