My aunt died of cancer a couple of years ago. She took an unorthodox treatment of extremely high doses of marijuana, which her husband encouraged. It was frustrating for the rest of the family since it was impossible to have a coherent and meaningful conversation with her in her final months. My dad and I had some doubt about it, but the decision was entirely in the hands of her husband because she was too inebriated to think for herself. I’m not saying it was a wrong choice necessarily, but there are downsides.
