My 83 year old mother is a cancer patient with no appetite. She is willing to try smoking, but her throat and lungs are very sensitive. I have access to weed and RSO. What are the least noxious ways to smoke for someone like her? She is definitely not a 'smoker', but needs some way to increase her appetite and her mood. We have already tried RSO by mouth and suppositories, but it doesn't seem to have much affect on her. I'd like to try smoking. Any suggestions? Thanks!
