I'm guessing that when smokers light up, 90% of the smoke is released into the air, between puffs - and only about 10% is taken into the lungs of the smoker. Who really needs scientific proof that 2nd-hand smoke is dangerous to people's health - and that includes the smokers themselves? Is it not proof enough that it makes cough, your eyes water, your nose and throat burn? Aren't those the body's first 'warning signals'?

Who among us would sit in an enclosed space with a smoky campfire burning and then argue about whether breathing that smoke all day long was good for you? Duhhhhh...

I'm looking forward to the day when everyone who chooses to use tobacco does so with proper care and respect for (1)themselves; (2)the plant and all of it's effects on human biology - including the mind and emotion; (3) the FIRE which burns it, and (4) everyone else's need to breathe fresh air. If all that were so, imo there'd be no health risks from smoking.
