I will echo the doctor conversation suggestion as like Newbeginning 421 notes...it is the THC not the CBD that is psychoactive. Certain cannibas products are legal in Canada. I know from a friend with a multitude of painful knee issues she had sought out CBD tinctures for pain but was trying one with zero or next to zero THC. I know from just my conversations with her that there are all sorts of tinctures with varying levels of THC...from zero to half and half to more THC to CBD.
Ya...doctor is the route I'd go.
