I havent had any trouble chewing on stand, to tell ya the truth i was on the ground last year by a cedar tree and hadent seen anything so i lit up a smoke, needless to say a mature buck came to investigate what was going on I think its like everyone else says deer are curious and when i dip up i dont think that the smell bothers them, I try not to smoke if i am on stand but i try to quit smoking and start chewing again well right around this time of year, 2 things that my wife hates, when i grow my beard for deer season and when i give her a kiss when I have a big ole dip in lol. good luck to everyone this season.
