"How often should you administer a cannabis suppository for rectal cancer?"
For rectal cancer, the medicine needs to stay in the pelvis for the most beneficial effect, so do not put the suppository too far up in the rectum where the blood supply will transport the medicine to the liver, just push it in past the sphincter and leave it there. Anything in that area can make you feel like you have to empty your bowels and you certainly wouldn’t want to do that right away so you might also want to lie down and rest for a while until that sensation has passed.
