In 1972 brain researchers from Johns Hopkins University made a puzzling discovery that would illuminate scientists’ understanding of drug addiction. But then there was the obvious question. Why would nature put in our brains a receptor for a plant?
After all, humans beings didn’t evolve over millions of years eating opium or shooting heroin. The scientists reasoned there must be some other function for these receptors sites. Endorphins are feel-good chemicals naturally-manufactured in the brain when the body experiences pain or stress. They are called the natural opiates of the body.
Endorphins flood the space between nerve cells and usually inhibit neurons from firing, thus creating an analgesic effect. On a lower level they can excite neurons as well. When endorphins do their work, the organism feels good, high, or euphoric, and feels relief from pain . Logically, endorphin levels go up when a person exercises, goes into labor, or is stressed out.
Although they seem to be triggered by stress, endorphins can do more than relieve pain, they actually make us feel good. Like an evil twin, the morphine molecule locks onto the endorphin-receptor sites on nerve endings in the brain and begins the succession of events that leads to euphoria or analgesia. This imposter is more powerful than the body’s own endorphins because the organism can actually control how much of the feel-good chemical hits the brain. Since we are all pleasure-seeking organisms, the motivation to self-administer such a drug is easy to understand.
The drawback, of course, is addiction. What Does Heroin feel like? After a few more uses, the beneficial effects are obvious. Some users have distinguished between the «rush» and the «high.
The rush lasts only one or two minutes and is said to be caused by the injected heroin bathing the brain before it gets distributed by the bloodstream and changed into a more useable form of morphine. The rush is often described as a heightened sexual orgasm, and a great relief of tension, which pervades the abdomen. After the rush, the high lasts for four or five hours and is caused by the morphine diffusing from the bloodstream into the brain.
It is described as a warm, drowsy, cozy state. There is also a pleasant state of mild dizziness that is not as impairing as alcohol’s effects, and a sense of ‘distancing’ or apathy toward whatever is going on in the environment. Some addicts lose the effect of euphoria, and use heroin only for relief of unpleasant withdrawal symptoms.
Since all opiates produce cross-tolerance, the use of codeine, opium or morphine can relieve the withdrawal symptoms of heroin. The mechanism of addiction is still not fully understood. Generally speaking, addiction is a socially-derived word that refers to a person’s compulsive use of a drug in spite of being harmed by it. Dependence and tolerance are conditions that can lead to addiction.
