2. At the anti-counterfeiting detection point, the real smoke turns blue quickly after being rubbed and heated by fingers, and returns to its original state after the temperature drops; After the fake cigarette is rubbed and heated by fingers, there is no change, the color of the detection point is dim, and there are obvious sawtooth marks on the edge.
3. The edges of the true smoke white font are regular and smooth, and the handwriting is full; The white font of fake cigarettes has rough edges, dirty colors and obvious jagged marks.
Extended data:
1. Adolescents' memory ability of smoking decreases:
Studies abroad show that for teenagers, whether they smoke recently or not, the accuracy of smokers' working memory will be impaired, and the younger they start smoking, the worse their cognitive function will be. Long-term smoking nicotine will reduce the number of cells in cerebral cortex, midbrain and hippocampus, change the cell volume, and finally show the decline of cognitive function.
Taking students from three vocational schools in Beijing as research objects, the team of the Center for Tobacco Diseases and Quitting in China-Japan Hospital explored the influence of smoking on the cognitive function of vocational school students.
It is found that smoking is not conducive to students' mental arithmetic and reasoning ability, short-term attention and executive function; The overall executive disorder and ideological and behavioral disorder of moderate and severe nicotine addicts are more serious than those of mild addicts. There is a correlation between smokers' starting smoking age and their memory ability. The earlier they start smoking, the worse their memory ability.
2. Middle-aged and elderly smokers are prone to Alzheimer's disease;
For middle-aged and elderly people, smoking is also bad for their cognitive function. A study found that smoking can lead to a rapid decline in the word memory ability of middle-aged people and slow down the visual search speed, and the decline in cognitive function is particularly obvious among smokers who smoke more than 20 cigarettes a day.
The same is true for the elderly. The degree of cognitive decline is positively correlated with smoking quantity and smoking age: the more you smoke and the longer you smoke, the more serious the cognitive decline is. Long-term smoking in the elderly can also lead to Alzheimer's disease.
3. Smoking affects cognitive ability:
Smoking can lead to the decline of cognitive function in adolescents and middle-aged and elderly people, and quitting smoking is an effective means to prevent cognitive decline. Teenagers, in particular, are in a critical period of intellectual development. If they are not advised to smoke, smoking will seriously damage their intelligence and their future will be affected.
For middle-aged and elderly people, the decline of cognitive function and even the occurrence of Alzheimer's disease will not only make them unable to take care of themselves in their daily lives, but also cause mental and behavioral disorders and a sharp decline in their quality of life, which will also increase the burden on families and society.
