@waningphilosophic Welcome to Mayo Clinic Connect. I see you have had some great responses to your question!

While I am not a transplant patient, my husband is a kidney recipient [Oct 2016]. We have been involved with renal support programs for many years, and I myself am a ESRD patient not eligible for transplant [on dialysis, though].

Transplant centers, no matter where you go, want to insure the best possible outcomes for their patients, and to offer the available kidneys to those who will comply with the standards that center has set out. The success rate for a recipient depends on so many factors, including co-morbidities, lifestyle, and compliance with protocol. While they can sympathize [most of the time!] with a patient using medical marijuana for pain control/appetite encouragement, they may want you to reduce or stop its use. I know of a person who had to be "de-listed" because he would not cease use of a substance his team banned. Eventually he did comply, and received a kidney.

I will be very interested to hear what your transplant team explains to you, and your decision.
