MasterCard, Visa and American Express are promoting contactless versions of their credit cards, which only need to be held near a special reader at the checkout counter for a sale to go through, making the standard card swiper no longer necessary.
Filters in a new and used cigarette. Cigarette filters are an essential non-tobacco part of a filter cigarette, and have a profound effect on the yield and composition of cigarette smoke. The filter may be made from cellulose acetate fibre, paper or activated charcoal.
Smokeless Tobacco. Smokeless tobacco, also called spit tobacco, includes chewing tobacco (dip and chew), tobacco powder (snuff), as well as flavored tobacco lozenges. These products also contain nicotine. Smokeless tobacco products allow tobacco to be absorbed by the digestive system or through mucous membranes. Smokeless tobacco contains at least 28 cancer-causing substances, and is not a safe substitute for smoking cigarettes or cigars. According to the National Institutes of Health, chewing on an average-size piece of chewing tobacco for 30 minutes can deliver as much nicotine as smoking three cigarettes.
