Well, you really should go off the weed. Marijuanna can show up weird on blood and urine tests and cause odd symptoms if the doctors aren't looking for it. It could alter your care and your prognosis.
The THC could certainly come up one day. All it would take is the doctor getting suspicious of you and testing, and that's it.
My suggestion: Get off the pot ASAP so you can calm your anxiety.
Best of luck!

You've somehow slipped through the cracks with this. Do yourself a favor and give it up or leave pain management ... you're playing with fire. Is it worth losing your pain management? And honestly, this is one of the reasons pain management patients sometimes find it hard to get their pain controlled.
