Hi, im asking if coughing out mucus spit like yellow green stuff , from smoking cigarettes is normal , i've been smoking for three years , but i recently quit and started back because i've been stressing lately and have anxiety and ciggaretes calm my nerves , im just wondering if its normal because i cough it out everyday and i don't have bad coughs its just when i cough yellow-greenish stuff comes out , im just wondering if its bad because my friends smoke and they don't always get bad nasty looking spit like i do.
