i quit smoking 4 years ago but i do dip when im hunting and i have never had a deer come in acting spookish. i think it has to do with the fact that it is a foreign scent and i wear a 3 layer system of scentlok. we all know deer in general are curious and will come in to investigate new smells in his house. but the way i look at it if you smoke in the woods or not it goes down to responsibility as far as the dangers of smoking in the woods with all the dry leaves. if your responsible in the woods with your firearm or anything else then there should not be any accidents. if your not responsible then you open yourself for accidents.
