I have graduated in 2018 and in college days I occasionally smoked cigarettes for 1.5 years(250 cigarettes)and I attended 3 hookah sessions.But after college I quit those habits because I learnt bad impacts of those things.After quitting I had shortness of breath and little coughing but doing regular exercise symptoms gone but in 2021 my bp was high.So I take medication of bp and now it is normal. I quit smoking for 5 years but I am concerned about my lung health in future for those habits.I feel regret for doing those things.. please give some suggestion!!
