This is a tough one. My brother is convinced that I am still smoking. I went threw my entire arsenal and can't convince him. I did agree with him that I still have the hand to mouth habit. Currently my wife is using the patch which is 7mg and I vape only 3mg. I tried telling him it is another way to deliver nic to be but he is a hard head. Any one have any ideas on this matter. I really believe this is the general public opinion on this. Wish they had studies done on it to inform people.
