| Then there is sidestream smoke, which is released into the environment when the smoker is not drawing on the cigarette. |
|
| In other studies, emissions of NDMA and other N-nitrosamines in ETS rather than in sidestream smoke have been determined. |
|
| Increased risks of lung cancer have been observed in non-smoking populations exposed to sidestream smoke. |
|
| The justification, as always, is that sidestream smoke is a threat to the health of innocent nonsmokers. |
|
| A cigarette paper having a sidestream smoke smell-improving agent characterized by comprising a salt of a hydroxy acid of a lactone. |
|

|
| There is no ventilation system that reduces or eliminates the carcinogenic products of second-hand smoke or the sidestream smoke from cigarette smoking. |
|
| Investigations of sidestream smoke suggest it is more dangerous than direct smoke. |
|
| The answer is this: the most toxic type of smoke is the sidestream smoke that is released into the environment, because it undergoes an aging process before it is inhaled. |
|
| Smoking accounts for 30 percent of all cancer deaths, and there is increasing recognition of the danger of environmental or sidestream smoke to the nonsmoker. |
|
| Moreover, how many people know that the concentration of nicotine is two to three times greater in sidestream smoke than it is in mainstream smoke? |
|
| Such secondhand tobacco smoke is a mixture of mainstream smoke exhaled by active smokers and sidestream smoke released from the smouldering tobacco and diluted with ambient air. |
|
| However, we also must note that we did not detect risk increment of breast cancer among active smokers who inhale sidestream smoke through their own smoking. |
|
| What is there about smoking that poses such dangers for the tobacco user and the nonsmoker exposed to sidestream smoke? |
|
| And the sidestream smoke from the tip of a burning cigarette produces substances even more toxic than those from actually puffing at the cigarette. |
