I don't smoke anymore but if I did, there is no reason that I could not smoke when out stalking. If the wind is wrong and they smell your fag, they would have already smelt you anyway!! In fact, it is useful to have a cigarette on the go as it will constantly tell you the wind direction.
That used to be one of the questions in the old test for the Woodland Stalkers Certificate and it was surprising how much conversation that subject generated.
Of course Andy L is quite correct. Always stalk in to the wind.
i don't realy like people to smoke whilst out with me as all the extra hand movements related from lighting up to stubbing out can sometimes alert deer to your presence and when you are trying to get in for a shot, being a non smoker it is an unwelcome smell, when you are shoulder to shoulder and smoke is wafting across your face, plus as it is getting dark the fag often lights up like a beacon giving away your actual position, then when you get into the vehicle to go home why do they allways want to hav those last few drags then breathe the smoke back into the motor.
on the positive side the smoke can act as a excellent wind direction indicator but i like to feel the breeze on my face or scuff the ground or even if cold enough just use my breath these are some of my preferd methods
I used to stalk with a mate of mine who smoked, and I didn't, we both obeyed all the rules of stalking, the only difference being he would sit up every now and again for a smoke. You have no idea how many beast's he got from these fag breaks, and I am talking about woodland stalking here not on the hill.
We have covered this subject before in the past on here, with various for's and against.
Personally to me what ever anyone says IMHO smoking will give you away quicker. My sense of smell is terrible, but I can smell cigarette smoke from a long way off, so a deer has even more chance and if you are in a wood with the wind swirling about this is going to travel further, and also it is on your clothes.
Testing the wind while you stalk with a fag in your mouth is fine if you want to go that way. BUT not with me you aint.
