Cigarette smoke contains a staggering 7,000 chemicals, and at least _____ of these chemicals are known to cause cancer.
Answer 70
As if there weren't already enough reasons out there to quit smoking, there are at least 70 cancer-causing chemicals in cigarette smoke! Sadly, almost 9 out of 10 smokers start before turning 18, and more than 3,000 children and teens start smoking every day.
