Cannabis should not be any problem post-transplant! Some side effects of cannabis to be mindful of is that cannabis can fluctuate your blood pressure, and if your taking blood pressure medications you have to be mindful of this. You want to maintain your blood pressure over 90/60 and under 180/120 for instance, or you can risk a heartattack or stroke. But, cannabis is a great anti-inflammatory and pain reducer which should help post-transplant. Many people use high CBD products post-transplant and do well. For individual treatment plan of specific symptoms I would need more information. Hope this helps!
