Hello Abhishek,

There is no direct relation found between smoking and studying but there can be an indirect effect of smoking on our memory and that will affect our studies.

As smoking results in lowering down the speed of blood circulation in our body and smoking gives us unusual pleasure.

It is the blood circulation in our body which matters the most so if the blood circulation is not good the performance of memory can slow down and this can affect in studying.

However there is no direct reltion but there is a indirect relation which is not found in newly started smokers but after smoking for a long time it affects the health and memory too.

Hope this may help you.
