If i've smoked marijuana for 5 years and quit. will all the pigments in my lungs be removed and will my lungs turn pink again?

Five more years : You've done the right thing to quit. Marijuana has about four or five times the tar found in regular cigarettes, so it can be just as dangerous to the lungs as regular cigarettes depending on how much you smoke. Five years is the length of time such that abstinence from cigarettes returns a former smoker to normal risk levels for most smoking-related illnesses, so you're well on your way.

Yes: Congratulations! cigarettes are worse on the lungs than marijuana. The main negative effect of marijuana is in the brain. Pot smokers literally become less smart in a way that interfere with their social success later in life (neuropsychological tests, iq cohort kind of study). Awesome achievement!
