from this one:
If you really think that you can take a cigarette, which has had all sorts of chemicals added to it, light it on fire and INHALE the waste products created by it - and NOT get sick… well, I dont know what to tell you. Maybe go inhale fumes from a burning tire or or melting styrofoam! Mmmmm Yummy!
Second hand smoke has been linked to respiratory problems in children, chronic ear infections, low birth weight.
None of this matters though, because for every link I find, there is one more out there with ‘evidence’ to the contrary. The tobacco companies have alot to lose by people being afraid to smoke - so of course they try to make it as non-threatening as possible.
The really sick part of all of this is if the friggin companies had left the tobacco in its natural form - the way it had been used throughout time - it wouldnt be so addictive, or as toxic. There wouldnt be 5000 chemicals in the smoke. Ideally, cigarette smoke should be no more harmful than burning hay. But it IS harmful - because of the addictive crap they coat it with.
