I have been smoking pots everyday for 2 and a half years, Im a singer and im trying to quit, its been on and off for a while but i wonder if i could clean my lungs completely and how long will it takes? and will my voice be recovered like how it was before? whats the best way to recover my body (esspecially my voice and my lungs)....how long does it usually takes to get rid of all the toxin in my body?
