Stopping smoking and alcohol before surgery has a major impact on safety and recovery.
Smoking
Stopping at least 4 weeks before surgery reduces wound complications, chest infections and DVT. Even 24 hours helps oxygen delivery.
Alcohol
Stop at least 48 hours before surgery. Heavy drinkers need supervised reduction to prevent withdrawal.
Vaping
Nicotine in any form still impairs healing — best avoided.
Support
Nicotine replacement therapy, counselling and apps significantly improve quit rates.
After surgery
Continuing to stay smoke-free improves long-term outcomes — many patients use surgery as a successful quit trigger.
