Whether it comes from tobacco, electronic cigarettes, cannabis or a hookah pipe, smoke is smoke and you should limit your exposure to it. This is specifically important for children, pregnant women, older adults and those with pre-existing health conditions, such as asthma, lung and heart disease.
Second-hand smoke contains over 7,000 chemicals with at least 69 of them known to cause cancer. There is no safe level of second-hand smoke.
Many of the same cancer-causing chemicals, carbon monoxide and heavy metals that are found in tobacco smoke are found in cannabis smoke.
The smoke from both tobacco shisha and herbal shisha contain carbon monoxide and other toxic chemicals that increase the risk of smoking-related cancers, as well as heart and lung disease.
The aerosol from e-cigarettes can contain potentially harmful chemicals like nicotine, ultrafine particles that can be inhaled deep into the lungs, organic compounds like benzene, and heavy metals like nickel.
