Drug abuse information clearly states drug abuse is an extreme desire to obtain, and use, increasing amounts of one or more substances.
The first question to answer is the effects of drugs on brain. Drug can effects the communication system and executive functioning in our brain, how they send, receive and process. They alert the way nerve cells work. Sometimes drugs consist of chemical that are similar to that …show more content…
Normally, dopamine is then re-uptake back into the transmitting neuron by a specialized protein called the dopamine transporter. If cocaine is present, it attaches to the dopamine transporter and blocks the normal recycling process, resulting in a buildup of dopamine in the synapse, which contributes to the pleasurable effects of cocaine.

• The body develops a tolerance to the drug and as use continues, it requires more and more to achieve the desired effect.
Brain Chemicals and Brain Structures: Morphine effects the amount of certain pleasure inducing chemicals in the brain. By stimulating the structures that release these chemicals, morphine acts to increase the amount circulating in the brain. In addition, there are naturally occurring opioids produced in the brain, called endogenous opioids. Morphine binds to the receptor sites for endogenous opioids and reduces the excitability of neurons. It is believed that this contributes to the euphoria experienced when …show more content…
It has same structure to our natural opioid that found in our body so it called exogenous opioid. It mimic the rule of the natural one, it manipulate our feeling of pleasure by increasing the amount of circulating in the brain via stimulating process and release our stress.
So we can say these chemical on drugs can affect our brain by either:
(1) Mimic our natural neurotransmitter
(2) Stimulating
(3) Increase the amount of chemical in brain,
(4) Trick receptors
