my brother recently was in a motorcycle accident and broke his femur. He had surgery and they gave him vicodin for the pain. during this time they scan his entire body and found a mass on his kidney. Currently has cancer and is having another surgery on the 9th. They told him he couldn't take is vicodin and ibuprofen or Tylenol or aspirin because it's in his blood. He is currently in a lot of pain. my question is can you use medical marijuana or marijuana every time to help with the pain before the surgery and he will be okay during the surgery?
