What are narcotics

Before starting to talk about everything that exists around the world of narcotics, it is important to know what exactly we mean when we use this term, since not everyone knows exactly what it means and what type of substances it includes.

First of all, a narcotic is a medicinal substance. Therefore, it causes a reaction and modification in how the body works, affecting different capacities depending on the specific type that it is and what it is indicated for..

Most narcotics act as an inhibitor of nerve signal transmission to prevent pain. However, it also acts for other purposes in the body depending on which is.

As their name suggests, they make you sleepy and have a depressing effect on the central nervous system. However, it is common that they are also used as stimulants in many cases, although they ultimately cause this depressant effect.

Within the group of narcotics there is a great variety of substances. Many of them are legal tender, such as drugs used for therapeutic purposes or some legal drugs with psychoactive effects..

Classification of narcotics

Narcotics are divided into two types:


On the one hand, there are opiates, which are so called because they contain alkaloids present in opium. These refer to substances derived from morphine, both natural and semi-synthetic..

Some of the best known opiates are codeine, heroin, and morphine. The first of them is very present in many medications, since it is used as an analgesic, sedative and as a drug to relieve cough.

For its part, heroin is also used for coughs and as an antidiarrheal, although much less frequently than the previous one. One of the best known uses of this substance is as a recreational drug, which is also highly addictive.


On the other hand, there are opioids. This is a type of agent that is used to primarily affect the central nervous system. The most important are oxycodone, hydrocodone and tramadol.

Oxycodone is especially powerful and therefore highly addictive. Another one, hydrocodone, is used as an analgesic to treat moderate pain and some more severe pain. Like the previous ones, you have to be very careful because they generate dependence and withdrawal syndrome.

They should always be consumed under a medical prescription

In any case, it must be taken into account that this type of substance must always be consumed under medical prescription, since they are potentially dangerous substances in that a strong dependence on them can be generated..

In addition, they can generate side effects and their own tolerance to the drug, which will make the person who consumes it need more and more doses to achieve the same effect that it had before with a lower consumption.

This will also generate a dependency and can even cause withdrawal syndrome in the patient, which can be even worse than the damage that the drug itself generates.

In short, narcotics are a type of substance that can be very harmful and dangerous. For this reason, it is convenient to know well what it is about in order to avoid ending up having problems with them if we must take them on any occasion..
