Remember, the longer you stop smoking, the better. However, if you have not quit, stopping smoking for at least 12 hours before surgery will help.
Stopping 72 or 48 hours before an operation can decrease some of the risks. Carbon monoxide and nicotine are cleared from the body in a matter of days. This can help to improve healing and recovery.
Smoking increases your risk of problems during and after your operation. Quitting 4–6 weeks before your operation and staying smoke-free 4 weeks after it can decrease your rate of wound complications by 50%.
Smoking before surgery increases the risk of experiencing lung, heart, and immune system complications during and after surgery. Smoking after surgery can also interfere with the body's healing process, which increases the risk of severe infections, coma, and death.
That's because marijuana raises a person's heart rate and lowers their blood pressure. Patients who get high before being sedated could see an increased risk of cardiac problems, including heart attack, Hepner said. Patients could also experience breathing problems from heightened airway sensitivity.
No smoking for at least 12 hours before surgery. Ideally, cut down or stop smoking as soon as possible prior to the day of surgery. A responsible adult must accompany the patient to the office, remain in the office during the procedure, and drive the patient home.

Tobacco smokers are at significantly higher risk than non-smokers for post-surgical complications including impaired heart and lung functions, infections and delayed or impaired wound healing.

Smoking decreases blood flow making surgical wounds less likely to close, less likely to heal well and more likely to become infected. Smoking also weakens the immune system, which increases the chance of infection after surgery.
The risk for anesthesia-associated reintubation, laryngospasm, bronchospasm, aspiration, hypoventilation, and hypoxemia is 1.8 times greater in smokers compared to nonsmokers. This rate is 2.3 times higher in younger smokers and 6.3 times higher in obese smokers.
