It's not uncommon to experience a cough when you first start using electronic cigarettes like RELX vape. This is because there is a transition period for your body to adapt to the new experience. To minimize the coughing, we recommend choosing a 0% or 18mg/ml nicotine pod for initial use and taking small, slow puffs. It's also important to drink more water and pay attention to rest. As your body gradually adapts, the throat and oral irritation, as well as other adverse reactions, will reduce, and your cough symptoms will also improve. Remember, quitting smoking altogether still requires your perseverance, as nicotine is still present in electronic cigarettes.
