Why Cigarettes Are So Addictive

The first thing to understand about tobacco is why people keep smoking. Experiments that measured brain-wave activity in humans have shown that nicotine screens out external stimulus like loud noises. In a practical sense, tobacco helps the user shut out the stress of noise and over-crowding in a big city. In one laboratory experiment, rats, which were given nicotine, demonstrated less reaction to painful heat exposure. So, smoking can actually improve some people’s concentration.

However, when smokers quit cold turkey, it is like a sudden increase in volume of the outside world. It would be like cranking up a stereo in a library. The smoker has difficulty concentrating and becomes irritable.

The most addictive part of tobacco is nicotine. Naturally-grown tobacco, which is used world wide, produces a small amount of nicotine ขายบุหรี่ไฟฟ้า. To make tobacco more addictive, North American cigarette manufacturers have made the following additions and changes to natural tobacco:

1. The nicotine is produced in an ammonia-salt, free-based form. It is absorbed more rapidly and delivers a more powerful kick. Despite a decrease in the amount of nicotine per cigarette, there is an increase in the delivery speed of the nicotine. (Kind of like free-based cocaine.) This ammonia technology is what made the tiny Phillip Morris cigarette company to become one of the top-selling cigarettes. In 1978, one in five cigarettes sold were Phillip Morris Marlboros, which was smoked by over 50% of smokers under 18 years. The cigarettes popularity with younger people had little to do with the male model portraying the Marlboro Man.

2. Theobromine, an active ingredient found in chocolate (from cocoa). It is a bronchodilator, which expands the body’s airways and lets asthmatics breath easier. When it is added to cigarettes, it expands the airways for increased smoke and nicotine intake. This forces more nicotine and smoke (and tar) into the lungs at a faster rate than natural tobacco.

3. Glycyrrhizin. Another bronchodilator that becomes carcinogenic when it burns.

4. Sugar. This makes the tobacco sweeter and more addictive to younger people. Sugar takes up about 3% of a cigarette’s weight. When it burns, it produces acetaldehyde, the same poison that alcohol produces in your body.
