What are narcotics?

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

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

Most narcotics act as inhibitor of the transmission of nerve signals to avoid pain. However, it also acts for other purposes in the body depending on which one.

As its name indicates, cause sleep and produce a depressive effect in the central nervous system. However, it is common that they are also used as stimulants in many cases, although they eventually cause such a depressant effect.

Within the group of narcotics there is a wide variety of substances. Many of them are legal tender, such as medications 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 called that because they contain alkaloids present in opium. These refer to substances derived from the morphine, both natural and semi synthetic.

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

For its part, heroin is also used for cough 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 the opioids. This is a type of agent that is used to primarily affect the central nervous system. The most important are the oxycodone, the hydrocodone and the tramadol.

Oxycodone is especially potent and therefore also very addictive. Another of them, hydrocodone, is used as an analgesic to treat moderate and some more severe pain. Like the previous ones, you have to be very careful because they generate dependence and withdrawal symptoms.

They should always be consumed under medical prescription

In any case, keep in mind 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 the own tolerance to the medication, which will make the person who consumes it increasingly need a greater amount of dose to achieve the same effect as before had a lower consumption.

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

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