"I take some cannabis tincture at night for fibromyalgia; it controls pain and helps me sleep. I only have one kidney and I had to go to emergency room because my urinary tract infection (UTI) made my kidney inflame. Is is safe for my kidney to keep using marijuana?"
Yes, Cannabis should be safe for you to use because cannabis is cleared through the liver and then excreted through the bowels. Hydration is a very important issue for you so always keep your body well hydrated in order to protect the one kidney you do have.
