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.
Regular cigarettes contain nearly 600 additives, 69 of which are carcinogenic. Unlike normal cigarettes which burn dried tobacco, e-cigarettes use a battery-powered device to heat a nicotine solution known as e-liquid. This produces an aerosol that can be inhaled (vaping). Higher end e-cigarettes allow the heat temperature to be adjusted, which can intensify the nicotine hit.
