The most dangerous drugs in the world


There is no doubt that drugs significantly destroy people’s lives , both physically, psychologically and socially. As stated in the World Report on Drugs prepared by the UN, 5% of the world’s population between 15 and 64 years old has tried an illegal substance. Drugs are estimated to cause about 200,000 people each year.

One of the countries in which drug use has increased the most is the United States . About 25% of deaths due to illegal substances in the world take place in the American country, generally due to opiates. Overdoses tripled in the United States between 1999 and 2015, from 16,849 to 52,404 per year.


Krokodil, also known as desoformin, is a homemade drug that is up to ten times stronger than heroin , as well as much cheaper. Its effects are terrible and, furthermore, irreversible. The name krokodil is due to the fact that the skin of the person taking this drug turns green and scaly, looking very similar to crocodile skin.

It is a drug increasingly used in Eastern European countries such as Russia . Generally, habitual users of it do not have a life expectancy beyond two years.

Desomorphine is made at home by combining gasoline, iodine , red phosphorus, paint thinner … A combination of ingredients that in many cases can be lethal.

Effects edit

The health effects of krokodil are catastrophic. The skin around the areas where the drug is injected will suffer from ulcers, causing the rupture of blood vessels . Thus, the tissues die and the chemical agents of the drug devour the skin; in some cases it can rot to the bone. In addition, teeth fall out and irreversible brain damage occurs.

The side effects of this drug are terrible: hepatitis , amputations, brain damage …


Krokodil has some of the highest addiction rates of any drug on the market ; it is practically impossible to put down. In case of stopping its consumption, people must go through a particularly hard and painful withdrawal period, which lasts approximately one month.


Another of the most dangerous drugs in the world is Whoonga, very popular in certain countries such as South Africa . This drug is especially consumed among low-income population groups, residents of the suburbs that surround the cities of Johannesburg and Pretoria, which are highly affected by unemployment and poverty.

It is a relatively new substance, which appeared between six and seven years ago and is made up of a mixture of marijuana, heroin, and other chemicals ; It is also sometimes made from rat poison and even drugs to treat HIV.

Effects edit

The health effects of this drug are in many cases lethal. Generally, after consumption, people feel strong abdominal pain ; After its continued consumption, the formation of ulcers in the stomach is one of the most common effects of Whoonga. It is the second deadliest drug in the world.


The origin of the massive consumption of methamphetamine is located in the middle of the 20th century , during the Second World War; The use of this drug was very common among the troops on both sides, generally to keep the soldiers awake. In the 70s, it was widely used to lose weight and, later, it was banned.

It is one of the most destructive drugs in the world , which can even change the personality and cause serious health problems. In addition, it is highly addictive; It is only necessary to consume it a few times to create a great addiction to it.

Effects edit

Methamphetamine is a highly addictive stimulant drug. Generally, it comes in the form of a powder that can be ingested or inhaled through the nose; The use of crystal methamphetamine, a drug that is smoked in a glass pipe, is increasingly common.

After consumption, this substance generates a wide range of positive feelings ; people feel happy and energetic. However, as time passes, joy gives way to nerves, excessive excitement, or even fear for no apparent reason.

Methamphetamine can cause serious medical problems, such as a rise in body temperature to the point of passing out , the sensation of severe itching in certain areas of the body, or even mental problems , such as difficulty concentrating.

From an emotional point of view, the personality of the meth addict can change considerably. Generally, people are anxious, confused, and even aggressive .

The long-term effects of this drug are very serious: rotten teeth, hallucinations, delusions, paranoia …


Heroin is currently one of the most widely used drugs in the world. It is the opiate whose action is faster. It is consumed in the form of a white or brown powder; heroin is generally mixed with other drugs or substances such as sugar or starch, among others.

Heroin is generally injected, snorted, snorted, or smoked. The vast majority of addicts opt for the intravenous injection as it provides a surge of euphoria in just a few seconds.

Effects edit

In just a few seconds after consuming it intravenously, people feel a great wave of pleasant sensations; they are euphoric. However, once the hours pass, there is a great sensation of dryness in the mouth and heaviness in the extremities. In addition, it decreases cardiac and respiratory function ; it is also common for consumers to feel drowsy for several hours.

The long-term effects of continued heroin use are devastating to health. Beyond the addiction itself, users can contract diseases such as hepatitis and HIV, as well as suffer from bacterial infections, abscesses and various rheumatological problems.


Cocaine is one of the most addictive drugs, which directly affects the brain . Furthermore, it is one of the oldest substances; Coca leaves have been ingested for several thousand years in areas such as Peru or Bolivia. As for the pure chemical substance, it has been consumed for about a century.

Generally, it is consumed through the inhalation of a white, fine, crystalline powder . It is snorted through the nose, from where it passes directly into the bloodstream through the nasal membranes.

Effects edit

The effects of cocaine appear practically immediately as its consumption; they disappear after just an hour. People feel energetic and euphoric . There are those who feel that they can accomplish tasks much faster; however, there are also people who feel the opposite effect.

The short-term physiological effects produced by the consumption of this drug include: blood vessel contraction, pupil dilation , increased body temperature …

As we have pointed out, cocaine is an extremely addictive drug. Therefore, it is very difficult for a person to control their consumption.

The brain begins to adapt to cocaine, so that it is less and less sensitive to its effects. Therefore, consumers are forced to take an increasing dose to obtain the desired effect. Continued inhalation can lead to a loss of the sense of smell, as well as swallowing problems or even hoarseness.

Long-term use of cocaine causes a great loss of appetite; thus, many addicts suffer from malnutrition and severe weight loss.

Drug use in the world

It is estimated that around 5% of the world’s inhabitants have used drugs at least once in their life ; in absolute terms, it involves no more and no less than 250 million citizens. Thus, the United Nations estimates that 29.5 million people suffer from some type of drug use disorder; Furthermore, the UN indicates that heroin is the main responsible for the negative health effects derived from the consumption of these substances.

Cannabis is the most widely used drug in the world, followed by amphetamines and heroin . The rebound in heroin use in recent years, especially in North America and Europe, is striking. Around 25% of hospital admissions due to acute toxicity have to do with heroin. Furthermore, between 2012 and 2015 heroin overdose deaths soared by 119%.

One in seven people who take intravenous drugs has HIV; and 50% have hepatitis.
