If I can't stop smoking should I forget about having a breast augmentation?

Thank you for your enquiry.

I advise my patients who are smokers to stop smoking ASAP
but no later than 6 weeks prior to surgery and try not to start after surgery.
One thing you should remember is that you will be having implants, so it is not
just the question of wound healing issues, but smoking may also increase the
risk of developing implant related complications such as capsular contracture
(hardness of the capsule your body creates around the implant). Unfortunately this
is not something that can be predicted in advance but it is important and
should be taken into consideration if you are a smoker and planning to have breast
implants.

Best wishes

Smoking is a bad health habit, period, so I certainly would encourage you to continue in your efforts to stop entirely.  However, most straightforward first time stand-alone breast augmentations are safe for smokers.  I would not perform or recommend performing a major mastopexy procedure in conjunction with a breast augmentation in a patient who is smoking.
