smoking or drinking?

Growing up with two parents who smoked like chimney's, it would be smoking, because it affected me personally. As a child, I begged, pleaded and cried to get my parents to stop. My mom still smokes (at 85, two heart attacks and a stroke). My dad quit in 1987 at the young age of 46, yep, lung cancer made him quit. Forever.

Both. Both can cause cancer. Both ruin your social life and health. Both are an industry to keep you enslaved.

Drinking can ruin lives.

drinking, because of all the violence and car fatalities that are related to it
