Smoke-Free Pregnancy (Tobacco and Cannabis)

Tobacco and Pregnancy

Quitting smoking is the most important step you can take to improve your health and protect the health of your unborn baby. A smoke-free space is best for you and your developing baby.

Smoking and exposure to second-hand smoke during pregnancy creates serious health risks for both you and baby.

  • It is never too late in your pregnancy for you to quit smoking.
  • Quitting at any time will improve your health and the health of your baby.
