I think it has been traditional for people to smoke cannabis for recreational as well as medical purposes, but I don't think that's the only way to use it, nor do I think it's the most effective way to use it. There are ingested cannabis-derived products—pills and other forms—that are more medically appropriate and that I think should be at the forefront. I think the state of development up to this point has limited its uses to the kind of traditional inhaled methods, and there are certain indications for those, such as acute nausea in a patient undergoing chemotherapy. But there are more refined types of products available to address that specific need, such as an extracted oil that can be vaporized in a device made for that purpose.
