Most vapers are worried about the sweet tastes they find in their e-liquid.nHowever, none of the components of e-cigarette products affect blood sugar except one: nicotine.nAs in smoked tobacco, it is the presence of too much nicotine that can be a problem.nNicotine blocks the regulation of insulin and thus creates resistance.nThus, nicotine can significantly increase blood sugar levels.nFor people with diabetes, it can cause hypoglycemia.nNote that unlike a smoker, the vaper can modulate the nicotine level of his e liquid and thus adapt a minimum dose not to affect his blood sugar.
