Opiate receptors are a type of protein found in the brain, spinal cord and gastrointestinal tract.
When opiate is taken into the body orally, through sniffs or by injection it is absorbed into the blood stream and reach to the receptors in the brain causing feelings of pain relief, euphoria and relaxation.
Opiate is beneficial due to its analgesic properties and is prescribed to patients suffering from chronic pain, cancer, surgical patients etc.
It relaxed the body immediately and gives a feeling of contentment.
Yet the worst drawback of this centuries old pain reliever is- addiction! Endogenous Opioid peptides are produced naturally by the brain to act as a natural pain killer, when opiate is consumed through pain killers it produces more of endorphins and dynorphins which make the body dependent on Opioid.
This dependency leads ultimately to addiction.
Opioid addiction adversely affects the psychological, neurological and physical system of the body.
Once Opioid enters the brain through the bloodstream it convert rapidly into morphine which activate  the receptors in the brain causing excessive release of dopamine, which is the main cause of addiction.
The addiction can have serious side effects like sedation, fatigue, insomnia, respiratory complications, hallucination and even cardiac arrest! An addict in an attempt to bring on the euphoric effect faster may chew, crush or break the drug and consume it orally or inject it directly into the blood.
The effect is a "kick" or a "rush" which gets you "high".
These feelings are so intoxicating that an unmonitored patient has an above 80% chance of getting addicted.
Not only does opiate addiction eat into your body and act like slow poison it also doesn't allow you to get rid of it.
Withdrawal can result in severe depression, nausea, circulatory collapse or even coma.
Opiate is like fire, an important discovery but if let out of control it can destroy everything...
