tobacco is usually used for smoking in cigarettes and cigars. Therefore, Smoking can change your appearance by altering your teeth, hair, and skin. Aside from your appearance, smoking weakens your heart, lungs, and bones; and reduces fertility.
Tobacco use can lead to hair loss, premature wrinkles, sagging skin, yellow stained nails and fingers, wrinkled lips, eye bags, damaged teeth and gums and possible also lose teeth. I hoped this helped :)
You should shelter in place under these circumstances. Your office is a safe enough environment that you would encounter more hazards by leaving rather than sheltering in place.
