my fitness is nowhere near were it should be..
If i didnt smoke I would be alot fitter.
I do the same activitys as my non smoking freinds and they are alot fitter than i am.
I can still Keep up i just have less breath..
even though i have a fit looking physique i am resperitorally Unfit.(my chest and lungs are constantly full of shit).(mornings and nights mostly).

sometimes I find myself less motivated If I smoke in the morning.
so i try to only smoke in the afternoons now.(exept my breakfast bong).

thats only my experiance with it though.
Like I said I still smoke every day so even though I know the Negetave effects I dont concerntrait on them and smoke anyways..
