The first thing you should know is that there are many different types of cigarettes, so it's important to understand what type you're smoking. For example, if you smoke menthol cigarettes, you may be less likely to feel the effects of nicotine than if you smoked regular cigarettes. Additionally, some cigarettes contain additives such as ammonia or sugar that can increase your risk for health problems. Finally, research has shown that secondhand smoke from cigarettes can also cause health risks.
