Not necessarily yes if you smoke it day in day out your gonna end up a bit f**ked up, But its the same with doing most things day in day out but if you pace your self by only smoking it occasionally like drinking at the weekend and just having a good time as long as exersise and just generley look after your self it could just make you life that bit more fun. I really do hate it when people assume if you smoke weed or take drugs then you are wasting your life yes in some cases this is true but only if you make it a habbit and let it control your life. I know quite alot of peole that take drugs and they are doing fine in life because they dont put drugs first if you do that then your going to fail, Thats how alot of drug related crime haens but it is never because of weed its mostly all the time because of drugs like smack and crack properly addictive drugs ,Cannabis it self is not an physically addictive drug if someone thinks they are addicted to it then its all in their head. Well there my view any way.
