How long after using my at-home teeth whitening kit can I smoke?

Question

I have found the same question, but the answer wasn't definitive enough. I'm worried that if I smoke even an hour after I use the gel (it says to do so for 20 minutes) my teeth will instantly go completely yellow again, or be even worse because of the enamel sensitivity. I would like to know if it gradually reverses the effects of the gel (like it gradually strained the teeth in the first place) or instantly? If instant, how long should I wait for this sensitivity to go away?

Teeth have a protective layer called the protein pellicule. This layer contains the surface dental stains and is removed during whitening treatments. It takes 24-48 hours for the barrier to fully develop again. Therefore, it's recommend to avoid tobacco products for 48 hours post-treatment. 
During the first 24 hours after whitening treatment, some patients can experience some tooth sensitivity or pain. This is normal and is usually mild, but it can be worse in susceptible individuals. Normally, tooth sensitivity or pain following a treatment subsides within 24 hours.
