Smoking while pregnant "biologically primes" the unborn child to become a regular smoker as a teen and young adult, according to a theory put forth by University of Arizona researchers. Somehow smoke is changing the brain chemistry," said the lead researcher, Dr. Roni Grad, an associate professor of clinical pediatrics at the university.
Maternal smoking during pregnancy is associated with low birth weight and problems at birth. Statistically, women are more likely to quit smoking during pregnancy that at any other time in the lives, but some pregnant women continue to smoke despite a strong and direct public health message.
Nearly a quarter of high school students in the U.S. smoke cigarettes. Another 8% use smokeless tobacco. Smoking has many health risks for everyone. However, the younger you are when you start smoking, the more problems it can cause. For example:
People who start smoking before the age of 21 have the hardest time quitting.
About 30% of youth smokers will continue smoking and die early from a smoking-related disease.
Teen smokers are more likely to use alcohol and illegal drugs.
They are more likely to have panic attacks, anxiety disorders and depression.
Parents and other adults who work with children can help by warning them of the risks of smoking. They can also set a good example by not smoking themselves.
