Smoked marijuana and cigarettes 10 days before BBL. Should I be concerned?

Smoking days before your surgery is something that nobody should do at all. In fact, smoker patients (that's what I recommend to my patients) should pause it, at least, 2 months prior surgery, and until a month after surgery (this time frame can vary). I don't know for how long you've been smoking, but I recommend you to consult a Specialist before your surgery, to check your lungs and make sure you're healthy for this procedure. It would be good for your Surgeon to have a clearance  before he works on you. I hope this answer was helpful.

Thanks for sharing your concerns with us. In my practice I always suggest my patients to stop smoking at least a month before surgery to avoid unnecesary risks and to persist without smoking at least 2 months after the procedure. Respectfully, Dr. Emmanuel Mallol.-

Greetings.  I recommend patients stop smoking at least 8 weeks in advance of a procedure.  The use of cigarettes and drugs can definitely increase the risk of complications.  Your plastic surgeon may consider delaying the procedure for the sake of safety and caution.
