Does Smoking Cause The Girth Of Penis To Shrink?

32 5'10 185lbs No medical history to report always been healthy. I have smoked cigarettes since i was about 15. Does smoking cigs cause the girth of your penis to shrink(it has NO problem getting a erection) If it does can you provide a website that states that it does. If it does will it get more girth if you stop smoking an how long will it take if so? Smoke about a pack a day of menthol. (not looking for someone to tell me i need to quit smoking i already know that. Just looking for the truth about girth.
