Okay -- that's your assignment. What specific questions do you have about it? Are you familiar with Google.com? It's a search engine that will help you find relevant information on the internet. Kind of like an electronic card file at the library.

Well, one is Nicotine.
Nicotine when consumed in small quantity is good (as in tea) , for it enhances the speed and efficiency of Brain to transmit impulses, as it gets in the synapse between neurons..
Excessive amounts may lead the brain to be in the habit of this enhancement and now its deficiency may lead brain unable to transmit an impulse in the absence of Nicotine in synapse (gap connecting two nerve cells) .. Hence, it is addictive.
Furthermore, it is hypnotic (sleep inducing) so more amt . is harmful..
Others are substances i don't have much inf upon.. but one of it is Carcinogen (Cancerous)
