I can't imagine anybody who would really think that smoking anything would help with breathing problems, but I'll be generous and suppose they meant well and just missed the mark by a mile or two. I do love the "they may be safely smoked by ladies and children" line in the above ad. The voice bubble coming out of the guy's nose is also a sight to behold. Then again, who am I to doubt the medical advice of a talking nose?
