Why if you smoke one stick cigarette get dizzy?

There's more than one reasons for this. Firstly, all the COUNTLESS toxins and chemicals that is released from a cigarette at one time in your blood stream causes your body to react to it in this way... because it hates it!!!

Secondly, the cigarette is robbing your brain of vital oxygen... which it hates also!!! The bottom line is, quit smoking before it becomes difficult because it may kill you slowly!
