I quit smoking in 4 days or so and my breathing is kind of heavy and short , I would finish a pack in some 4 days or less at times 1 day or 2 and I would smoke swisher tabacco blunts , how long does it take to get my normal breathing back to normal ? I'm young on my teen years , 17 about to turn 18 I know this is bad but it's addicting but I quit now And , how do I notice if I had some kind of affect on smoking cigarettes?
