I definitely wouldn't recommend smoking in that case, but vaping you could try if you make sure the vape is not getting too hot. If you do vaping right it's basically warm, spicy mist - still may make you cough, but could be manageable if you're careful. The effect is a lot more immediate from vaping, is the only reason I'd at least consider it in your case. You can also try ingesting it orally for a slower uptake, though I'm not sure what a good dosage or way would be for you. Can't really OD on CBD though, so don't stress it too much. If you go that way just beware, there are a lot of snakeoil products out there with CBD. I'd try going for a basic oil extract from a reputable vendor that ideally also sells whole flower, that should give you a pure, reliable, versatile solution for oral ingestion. You could put it on food or even bake with it (I think), take it any way you would ingest oil. Alternatively, you can solve it in alcohol, but I don't think that's a great idea for your use case.

There's probably also CBD in pill form some way or other, I'm sure
