Kids More Apt to Smoke If Mom Did While Pregnant

TUESDAY, May 19 (HealthDay News) — 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.

“If you are exposed to smoking prenatally or in the early years of life, you are much more likely to be a chronic smoker at the age of 22,” Grad said.
