After my scaphoid fracture is healed through the screw, can I start smoking again?

Depends. Do you want to continue to subject yourself to a high risk of emphysema, heart disease, stroke, and cancer, or would you like to avoid this increased risk. It's hard to quit smoking, but when you get older and you're very sick, you'll wish you had quit when you were younger. Stop now before the consequences become irreversible.
Scaphoid fracture. It will be nice if you stopped smoking.
