“The evidence is clear.
There is no safe level of exposure to second-hand tobacco smoke,”
“Many countries have already taken action.
I urge all countries that have not yet done so to take this immediate and important step to protect the health of all by passing laws requiring all indoor workplaces and public places to be 100% smoke-free.”
~WHO Director-General, Dr Margaret Chan
For example, in China it is difficult to find restaurants or any out door public locations that ban smoking.
Other countries need to beware that secondhand smoke effects the health of everyone including animals, plants, infants, children, the elderly, and adults alike.
Anyone in the presence of secondhand smoke becomes a passive smoker.
