First of all, the most obvious reason why we have to keep such strategy is that the rapid physical growth of younger people does not mean they are emotionally mature. Even though they may not be able to find any difficulty in smoking or drinking, they are still too immature to distinguish what is right and wrong. That is why they have to be protected under legal circumstances and be limited from doing something that could be harmful at early ages. Secondly, smoking has already proved to be harmful for many people of all ages. That means that, at whatever ages they are smoking, it is still harmful for them. In the case of smoking, young teenagers spend most of their time studying. However, by committing alcohol abuse during adolescence, they must cause many different social problems. According to recent research, the students who drink heavily and frequently have shown impaired memory ability, being three times more likely to attempt suicide than those who do not drink. Most certainly, there is no study on how much better the younger generation’s bodies have developed in comparison to the previous generations. Therefore, we should not decide yet to ease the restriction on under-age drinking and smoking policy.

It seems as if we should not ease the restriction on under-age drinking and smoking policy at this stage due to several reasons. Whatever has taken place, it is generally true that smoking and drinking at early age are very harmful and further problems associated with them can be caused by the younger people who abuse them. Scientists need to study more on how human beings' bodies have developed and, until then, such a furious debate should be suspended.
