Oral Cancer Patients and Vapes

After being recently diagnosed with squamous cell carcinoma of the oral tongue and undergoing a chemo treatment, I've really needed to come back to smoking cannabis more regularly (after a few month hiatus) in order to keep a healthy appetite. The docs give you "anti-naseau" pills but nothin' makes you actually want to eat like some good herb. I was wondering if anyone knew anything about vaporizers and how well they would limit infection in an open wound in the toungue (say, from a partial glossectomy). I would guess quite a bit, since most infections stem from the tar and shit and not from cannabinoids and thc.

Just wondering if anyone had any experience with such matters.
Thanks,
and as always,
Enjoy every toke.
