Local health officials are urging everyone to limit their exposure to second-hand smoke.

It’s National Non-Smoking Week, and the Chatham-Kent Public Health Unit says smoke is smoke, regardless of the source.

According to the Health Unit, smoke from tobacco and marijuana contain fine particles, heavy metals, carbon monoxide, and cancer-causing compounds, and there is no safe level of second-hand smoke.

They say avoiding second-hand smoke exposure is especially important for children, pregnant women, and older adults with lung and heart diseases.
