smoking

I'm not sure if this is the right forum I apologize.

I recently picked up smoking and I was wondering if there is some information regarding whether or not smoking effects penis enlargement positively or negatively? I smoked my whole life on and off. I want to quit because it's expensive and have lifelong repercussions. if I smoke less does it affect my erection less?
