15 Most Dangerous Drugs

15 Most Dangerous Drugs Resurgence – Whether you’ve used the most dangerous drug in the world, or other drugs, finding help at a treatment center can help you get clean.

The Most Dangerous Drug in the World

Despite awareness campaigns and the tightening down of government agencies’ restrictions on drugs, there are still increasing numbers of individuals becoming addicted to drugs. It’s estimated that overdose deaths have been rising by as much as 20% each and every year, causing many to wonder what the most dangerous drug in the world is?

At Resurgence Behavioral Health, we recognize that many are coming through our doors to seek out drug addiction treatment. However, we also understand that many are still experimenting with drugs. There is plenty of awareness about the opioid epidemic gripping the nation. However, other dangerous substances and drugs to be aware of, some of which you might not consider dangerous.

That’s why figuring out the most dangerous drug in the world may be more complicated than you think.

Immediate Placement in Rehab for Drug Abuse

To continue with awareness, and recovery, it is important to be aware of some of the most dangerous and addictive drugs.

15 most dangerous drugs

1. Opioids

What do you think of when considering the most dangerous drug in the world? Odds are good that opioids come to mind. They are highly addictive. Opioids also have some of the highest records for addicts overdosing. When opioids are taken, they enter the opioid receptors in the brain. Many are prescribed to treat pain.

They also bring an increase in euphoric feelings. There are several prescription drugs that fall within the opioid class. Many of them number among the most dangerous drugs. Opioid addiction can be alarming as it typically begins innocently. Many of our patients in recovery at Resurgence Behavioral Health were prescribed the medications they later abused. They are often prescribed after surgical procedures, or as a part of a pain management program.

Unfortunately, tolerance can be built up. This often leads patients to take stronger doses in order to chase those euphoric feelings. It is also all too easy to overdose on opioids, making them a good contender for the most dangerous drug in the world.

This drug is not a prescription. There are limited resources about the drug itself. An ingredient called desomorphine is used as the primary base for the drug. This is a semi-synthetic opioid that was developed for medical applications. Other ingredients are added, including dangerous chemicals like gasoline and lighter fluid.

Some side effects seen with this drug may include the following:

  • Infections on the skin and other soft tissue
  • Pneumonia
  • Meningitis
  • Blood poisoning

A rehabilitation and recovery program can help patients to break free from what is one of the worst drugs on the list. Could Krokodil be the most dangerous drug in the world? Many would say so.


Heroin produces intense euphoria, by activating the opioid receptors in the brain. Generally speaking, heroin can be bought for less than prescription opioids. This makes it popular for those who are chasing the opioid high. At Resurgence Behavioral Health, we see many who’ve moved on to heroin from hard-to-get prescription opiates.

Drug dealers cut the drug with other substances in order to maximize availability and profitability. These substances can be life-threatening. It is also easy to overdose on heroin, as tolerance can quickly build up, another reason some consider it the most dangerous drug in the world. Another reason it may be the most dangerous drug in the world is how easy it can be to get.

Detox is needed in order to recover from an addiction to heroin. Our recovery professionals at Resurgence Behavioral Health understand the detox needs of our patients. We work as a team to ensure your comfort and your safety.


Imitation psychedelics are seeing an increase in popularity. These drugs are much more dangerous than traditional hallucinogens. N-Bombs are a type of drug that is described as offering the same euphoria felt with ecstasy. But they also bring with them the hallucinations that are a hallmark of LSD. Because they are comparable in effect to LSD, many don’t consider them the most dangerous drug in the world. But are they right to feel safe?

Drug addicts simply don’t know enough about the drug or know enough about how to take them. They are much more potent than what is experienced with “traditional” psychedelics.

N-Bombs can be fatal at higher doses. It is also possible to overdose without much awareness of the overdose. Signs of an overdose may include heart attack, respiratory arrest and death. For those who have succumbed to these overdoses, N-bombs may be the most dangerous drug in the world.


Cocaine is a commonly abused addictive drug. This white powder is a popular choice in party drugs. This is due to its ability to stimulate those who take it. Users are left wired and with an inability to sleep. Cocaine is snorted.

However, the crystal version of cocaine, known as crack, is smoked. This makes it much more potent and addictive than cocaine. It can also prove to be cheaper than cocaine, which increases its popularity. Entire communities have crumbled due to crack, making it seem like the most dangerous drug in the world to many.


Highly addictive, methamphetamine is a stimulant that offers an immediate high. Made from a blend of toxic chemicals and pseudoephedrine, the effects of the drug typically don’t last long. This can lead addicts to take increasingly larger doses, easily making it competitive for the most dangerous drug in the world.

Meth is incredibly addictive and detox is needed in order to break free from the drug. The withdrawal process can be challenging, which is why it’s important to trust in the experience and knowledge offered by our team of professionals at Resurgence Behavioral Health.

7.Bath Salts

With an exponentially increasing popularity, bath salts are an addictive drug. They are typically easy to get. They are highly addictive stimulant drugs that produce a reaction very similar to amphetamines. Abusers of the drug may experience violent behavior, extreme paranoia, and hallucinations.

The chemical makeup of bath salts earns it a high potential to be the most dangerous drug in the world.


Strictly speaking, ecstasy is not considered to be physically addictive. However, this stimulant drug provides a mild hallucinogenic effect. It offers users a boost in energy and an intense euphoric feeling. The drug released an intense combination of dopamine, serotonin, and norepinephrine. It’s common for drug addicts to feel intense depression once the drug leaves their system.

However, there are some withdrawal symptoms to be aware of. Many users will need a detox program, and a team of professionals, to help ease the uncomfortable withdrawal symptoms, and lingering mental health effects make it more likely to be the most dangerous drug in the world than you might think.

9.Gray Death

When addicts find themselves spiraling and desperately chasing that high, they tend to take dangerous steps. Gray death is actually a blend of opiates, crushed together. The result is a gray-in-color powder. What sets this drug as a possibility for the most dangerous drug in the world is is that every batch is blended differently. It is typically a blend of opiates that include fentanyl.

Other drugs and substances are often added to the mix. It is incredibly easy to overdose on gray death. Respiratory depression and death can occur with overdose.


Very similar in chemical makeup to bath salts, flakka is made using cathinone. It is incredibly addictive. There are some very dangerous side effects seen with this drug.

Paranoia, hallucinations, explosive violence, and even self-harming behaviors are seen. The drug can also induce heart attacks, kidney failure, and suicide—no wonder it is often considered the most dangerous drug in the world.


LSC is considered to be non-addictive. It is also not considered to be dangerous, generally speaking. The effects of the drug make it still one of the most frequently abused hallucinogens today. There are few reported fatalities associated with LSD. However, the side-effects of use and the hallucinations can result in accidents and injuries.


While fentanyl is an opioid, it deserves its own spot on the list. This could very well be the most dangerous drug in the world. It is highly addictive, offering between 50 and 100 times the potency that is seen with heroin and morphine. It requires users to enter into a fentanyl addiction treatment program in order to see recovery success.

13. Benzodiazepines

These prescription medications are typically prescribed for treating anxiety and panic disorders. While overdoses are rarely fatal, increase the risk of death from an overdose when combined with other drugs or alcohol. Alone they are not particularly risky but mixed with other drugs, a benzodiazepine can be the most dangerous drug in the world. The skyrocketing numbers of prescriptions for these medications is indicative of the skyrocketing potential for abuse.

14. Spice

Spice was once available over-the-counter. It is now illegal and banned in many states. Just like marijuana does, spice has an impact on the cannabinoid receptors in the brain. This synthetic blend of herbs and chemicals is more potent and dangerous than marijuana, although not likely to rank as the most dangerous drug in the world.

Many who have used spice also find themselves addicted to marijuana. While marijuana is considered legal in many parts of the world, it can still be considered to be addictive.

15. Carfentanil

Like fentanyl, this drug is an opioid. It is said to be 100 times stronger than fentanyl, and up to 10,000 times stronger than morphine. Carfentanil is indicated for the tranquilizing of large animals. However, it has been found mixed with street drugs.

Gray death and heroin both have been found cut with carfentanil, making it a strong option for the most dangerous drug in the world. This can exponentially increase your risks for overdose and death. Are you wondering, “What is the worst drug?” In truth, the worst drug is the one that is controlling every aspect of your life.
