@Bushdoc alright man. Here’s the run down for pancreatic cancer based on the latest research and what she needs/wants.
Pancreatic cancer cells have been found to have cannabinol (cbn) receptors and they respond to cbn, cbd, and thc in lab studies though no human clinical trials have currently been completed. The lab study showed that cbn, cbd, and thc both natural and synthetic had antiproliferative effects on the pancreatic cancer cells.
So, to best help treat her cancer and nausea a high thc/cbd cultivar should be used and harvested just past peak ripeness to increase levels of cbn (which also has narcotic painkiller like effects in combination with thc and other terpenes such as linalool and myrcene).
For day use to assist with nausea and pain something like the Amnesia Haze auto or the CBD white widow 1:1 would work pretty well.
For night time use to help her sleep some edibles made with the cbd white widow or gold leaf will help ease pain and inflammation long enough to help her slip into sleep.
Smoking and edibles will be her best options for treatment. Smoking for immediate relief and curbing the nausea so she can eat and take the edge off until the edibles can kick in. If the cancer possibly spreads to her liver or she potentially loses liver function at that point in time her treatment would be more limited. Her only options would be smoking, sublingual, and suppositories.
