                                Nicotine is a known mild diuretic, which means it causes the body to expel water more quickly, increasing the risk of dehydration. For this reason, many ask, "How much water should a smoker drink in a day?" The answer is that their daily fluid requirements are elevated compared to non-smokers to counteract nicotine's dehydrating effects.
