Final answer:
It is necessary to wash your hands after handling tobacco products to remove carcinogenic residues and protect against the health risks associated with second-hand smoke.
Step-by-step explanation:
Yes, you need to wash your hands after touching tobacco products. Tobacco and second-hand smoke are considered to be carcinogenic, and hand washing helps eliminate residues of harmful chemicals, such as nicotine and other toxic substances present in tobacco products. Even if you are a non-smoker, second-hand smoke can still pose significant health risks. Chemical compounds released from tobacco smoke can adhere to skin and other surfaces, and these compounds include known carcinogens and toxins that may cause a variety of health issues. Proper hand washing for at least 20 seconds using soap and warm water is crucial in removing these harmful pathogens and reducing potential health risks.
