Secondhand smoke globally kills more than 600000 people each

Secondhand smoke globally kills more than 600,000 people each year, accounting for 1 percent of all deaths worldwide. Researchers estimate that annually secondhand smoke causes about 379,000 deaths from heart disease, 165,000 deaths from lower respiratory disease, 36,900 deaths from asthma, and 21,400 deaths from lung cancer. Children account for about 165,000 of the deaths. Forty percent of children and 30 percent of adults regularly breathe in secondhand smoke.

Solution

Secondhand smokers death in a year = 600,000

Adult death ( due to secondhand smoking) = 600,000 - 165,000 = 435,000 in a year

output lost = Adult death * output per person = 435,000 * 90,000 = 39150000000 = 39.15 billion
