Well, I'm a nursing student, and I'm pretty sure there's nothing to worry at all. You should check your bloodsugar level 30 and 60 minutes after smoking; and if your bloodsugar level is high, you drink lots of water and you exercise. If your bloodsugar level is low, you eat something like chocolate or candies; and then slow-released sugar: a fruit, milk, cheese.

Only one thing to worry about: If you smoke, be careful not to have munchies; cause then, your bloodsugar level will skyrock.

Peace,

Nurse
