Direct Biological Evidence Found
As regards the question whether smoking kills brain cells, there has been direct biological evidence that has been discovered by scientists. That would certainly help to act as a greater incentive to stop people from smoking and urge them to discontinue such a habit. Anti-smoking groups are promoting the latest finding in a greater way so that people are discouraged to take up a smoke the next time.
The research conducted comprised of three groups of rats who were given varying levels of nicotine:
- One group was given low levels of nicotine
- One group was given moderate amount of nicotine
- The third group was given high amount of nicotine
- The fourth group was not administered any nicotine
The findings were:
- The rodents which took on higher to medium doses of nicotine suffered a loss of 50% of their brain cells and the production of brain cells
- The rate of brain cell death was higher
- The non nicotine group did not show such rate of loss of brain cells or reduction in brain cell production
- There was a fall in a protein of the brain, PSA-NCAM that occurred in all rats which took in nicotine in different amounts
Such findings add onto the concerns that are already associated with health and nicotine abuse. The study throws light on the effects of the neural mechanisms of the brain due to the influence of tobacco or nicotine. Though there is no surprise regarding the inclusion of nasty chemicals in tobacco and the effects of it on the health of an individual, the current finding of the effect of the nicotine on the brain cells should certainly give food for thought to the students. There are myths that smoking helps one to concentrate and think. That is again dispelled by such research findings. It is imperative that such findings be given due to recognition by parents and youngsters themselves.
