The British Medical Association is asking its government to impose a ban on smoking inside automobiles.
    
Their research shows riding in a car with smoke exposes people to 23 times more toxins than sitting in a smoky bar.
      
Children are even more vulnerable since they absorb more pollutants. Smoke can linger in cars long after cigarettes have been smoked, affecting more kids.
   
Smoking in public vehicles is currently banned in the United Kingdom. But there is no law against smoking in private cars.
      
In parts of the U.S., Canada and Australia smoking in cars is banned when children are present.
