Could my sore throat and cough be related to smoking, despite my reduction in consumption?

Yes, it is possible that your sore throat and cough could be related to smoking, even if you have reduced your cigarette consumption. Smoking is known to be a risk factor for respiratory infections and diseases, and even with decreased consumption, the harmful effects on lung health can persist. The best way to reverse the negative effects of smoking is to quit completely. Community pharmacists can provide various aids to help you quit smoking, so I recommend consulting them. If you are experiencing sudden onset sore throat and cough, it is important to consider getting tested for COVID-19, as these symptoms can be associated with the virus. Quarantine and following hygiene measures are essential if you have flu-like symptoms. It's important not to panic, as serious complications of COVID-19 are rare. Getting tested for COVID-19 is the first step, and based on the result, further action can be determined. I hope this information is helpful, and feel free to reach out if you have any other questions.
