Smoking kills you

so far I still ask myself why there are still many people fill empty time with smoking, when it is clearly written on one of the body of the box "smoking kills you". after I interviewed some addicts who have repented from cigarettes apparently the answer is very unbelievable, they say we can not read so we are not aware of the consequences, but now we have been able to read clearly since had several times bersilaturrahmi with doctors and know the consequences of smoking .
