Non-smokers can be exposed to toxic substances through several sources:
1. Secondhand Smoke: Non-smokers can inhale smoke from the burning end of a cigarette or the smoke exhaled by smokers. This is known as secondhand smoke or passive smoking. 2. Environmental Pollution: Airborne toxins from industrial emissions, vehicular exhaust, and other sources can affect non-smokers. 3. Occupational Exposure: Certain jobs may expose non-smokers to chemicals and other hazardous substances. 4. Household Products: Everyday items such as cleaning agents, paints, and pesticides can release toxic fumes. 5. Food and Water: Contaminants in food and drinking water can also be a source of toxins.
