I would hope you wouldn't need the same amount as is needed orally, I think 69ron might be mistaken, those accounts that he read could have been wrong. I suppose the hcl could be harmful, try starting with 30mg. Lime? for basing, then hcl wouldn't be a problem right? I don't know of any base that would work to make it smokable, calcium carbonate is supposed to be no good for smoking form. SWIY doesn't have a smoking device, wow, dose a friend? Homemade would work. keep us updated. Too will I.
