Come on if you really wanna get those lungs open, either smoke european marlboro's (really crappy tobacco and worse filter) or a pack of cloves...watch ur times go to hell
...or better yet don't even freakin start smokin! take it from some who smoked for 3 years....not fun when u can't breath after runnin 20 min
...f*** all the advice about smokin an running, just don't do it an u'll do fine
All you haters can burn
