This is my bottom line, and the reason I DC all scheduled meds on any pt with THC in the UDS. I told a guy today I don't care if he uses CBD oil but a dirty UDS is a dirty UDS and he's a work comp guy I'm trying to wean off Percocet. If he pops for THC it is DC with no wean...baclofen, clonidine, Zofran...if you have THC and opioids in UDS you are not in compliance and may be prosecuted.
To be legal, CBD oil must be less than 0.3% THC but you can still pop for it, and I have a fear of dudes using CBD just so they can blame their failed urine on it when they are actually smoking weed.
I don't manage opiate dependency/abuse, however from what I understand, there is more tolerance to "slip ups" in that patient population since the goal is to control their addiction, not treat pain.
Fun study. But beyond useless. They had 25 self reported marijuana users out of 250 patients undergoing colonoscopy. Self reported use. Not tested for. And percent additional meds used was less than 20%. Lots of potential confounders. But fun to postulate. Not worthy of publication in a peer reviewed journal.
As an anesthesiologist, this 100% matches my experience.
