Consequences of heroin are vast, uncontrollable and severe and this is why heroin is considered as dangerous as it is.

Therefore, people need to have heroin to trigger the feeling of reward and that is what makes it addictive.
Neurones are specialised cells that make up the brain and nervous system. They send messages electrically, chemically, and they are excitable cells. It is predicted that the brain includes around 100,000,000,000 neurons in total. Each neuron receives and transmits impulses/information around the body. Furthermore, different neurons are responsible for different jobs in the body. Neurons are specialized as they contain many key parts that make them distinguishable: dendrites (where electrical impulses are received:...
