Is there a way to remove tar from my lungs?

To quit. But if you do continue to smoke, I personally recommend to try a steam inhaler device or sauna baths. There's Vick's Steam Inhaler online and other brands, and there's sauna/steam machines online too you could buy. Seems to clear my air pathways. They still haven't made an inhaler or nebulizer solution for this or any time of steam product for tar removal. But try going to a sauna, steam bath, or, boil water and inhale the steam and cover yourself in a blanket and inhale the vapor and theu could try Vick's steam inhaler, they have mentholated add on inhalation pads too. Inhaling regular non-harmful temperature steam can make ur lungs healthier from smoking by clearing the pathways and moistening your lungs more, it works for me. In Sweden, every house has a Sauna Steam bath. It'll also detox your pores. If you breathe better, the tar should come out faster over time. But you should definitely just exercise and quit, since you're young. Not smoking or quitting for periods of months or years works too or quitting totally is best, there's also chewing nicotine gum, while waiting for your lungs, to clear. Or if you insist on smoking still, try a cleaner smoking method. Shisha/hookah is a traditional tobacco water pipe, has flavors, and ice can be added to the water. But don't vape, vaping is worse, ppl have died from vaping. But don't vape. Anyway, lungs clear theirselves over time. But maybe do jogging and maybe a steam inhaler might help you.
