Well to tell the truth what the smoke does is to force the Stomata to close.

The Stomata are tiny breathing pores located on the underside of the leaf. The Stomata open and close to regulate the flow of moisture, preventing dehydration.

That is why you should never smoke around your plants.

Plus do you want them to know what's in their future? lol
