Can cigarettes effect someones mood?
Yes they can effect mood. More than that though there is a soft of ritual that comes with smoking. I come to associate me being in a certain state of mind with having a cigarette. I think that it is more the mental association and dependance than the chemical effects in some situations. Some of the problem may also be that issues surrounding the fact that he smokes is actually causing some of the issues. For example guilt over not quitting, pressure to quit, association of cigarettes with any emotional problems. I wish I could help more but thats all my expierence allows me to say. Wish you the best of luck.
