Monkey dust is a synthetic drug that has received significant media attention in the UK in recent years.

Headlines such as “The drug that makes people jump off buildings” and “Monkey dust like ‘dancing with the devil’” have often created confusion about what the drug actually is and how it affects users.

While some outlets may only look to exaggerate some claims, monkey dust is an undeniably dangerous drug, with serious physical, psychological, and behavioural risks.

It’s important to know the dangers of monkey dust, so we’re going to take a closer look at what it is, its effects, risks, and the treatment options available for you.

What Is Monkey Dust?

Monkey dust is one of many synthetic cathinones, a group of stimulant drugs that are sometimes collectively referred to as “bath salts.”

Monkey dust is the common street name for MDPHP (methylenedioxy-pyrrolidinohexanophenone), though sometimes the exact content of what’s in it varies.

Though the contents can be different, all synthetic cathinones are chemically related to compounds found in the khat plant, created in labs to be more potent and unpredictable.

Once created to get around drug laws, monkey dust and all synthetic cathinones are now illegal Class B drugs.

Why Is It Called Monkey Dust?

Monkey dust in the UK gets its name from how it commonly comes as yellowish powder, and there are stories of users attacking others whilst using it, scaling structures and acting erratically.

The name monkey dust is just one of the street names of the drug, rather than a scientific term. As there are many synthetic cathinones, with slightly different chemical makeups, different regions of the country may use the same name to refer to slightly different substances, creating confusion about the drug to the wider public.

Why Do People Use Monkey Dust?

There are various reasons why someone may start using, such as:

  • Want an escape
  • Think it will enhance a night out in a club
  • Peer pressure
  • Easy to get
  • Cheap
  • Coping mechanism for mental health issues

What Does It Look Like?

Monkey dust can come in numerous forms. It can be

  • Yellowish or off-white powder
  • Crystals
  • Capsules
  • Tablets

In these forms, it’s impossible to reliably identify the contents or strength of the drug, making it dangerous to take.

How Is It Taken?

It can be taken many ways:

  • Snorting
  • Swallowing
  • Smoking
  • Injecting

How you take monkey dust can affect how quickly the drug takes effect, the intensity of the effect and influence the risks of the substance.

How Does Monkey Dust Affect the Body and Brain?

Synthetic cathinones act as stimulants due to their effects on the brain. It hijacks your brain’s neurotransmitter systems, impacting dopamine, serotonin and noradrenaline, which brings on the feelings of stimulation, alertness, and euphoria.

Physically, it can dull pain and cause a rapid rise in body temperature, as well as an increased heart rate.

Chemical composition and potency can change batch to batch, which leads to the effects of monkey dust being unpredictable and causing volatile reactions with other substances unknowingly.

What Are the Effects of Monkey Dust?

The effects of monkey dust can kick in quickly, taking as little as 10 minutes. Common short-term effects of monkey dust include:

  • Increased energy
  • Alertness
  • Euphoria
  • Increased confidence
  • Agitation
  • Restlessness
  • Rapid heart rate
  • Elevated blood pressure

As stated above, monkey dust is unpredictable. What you experience can vary significantly depending on dosage, purity, and individual factors such as your weight, metabolism and whether you are using other substances.

What Are the Psychological Effects of Monkey Dust?

Monkey dust has become synonymous with mental health crises and emergency interventions due to the potent psychological effects of the drug. Monkey dust mental health risks include:

  • Anxiety
  • Panic
  • Aggression
  • Paranoia
  • Delusions
  • Hallucinations
  • Confusion

Why Is Monkey Dust So Dangerous?

Monkey dust and its risks are so pronounced and commonly linked to severe psychological and behavioural issues because of effects like:

  • Severe psychological reactions
  • Risk-taking behaviour
  • Cardiovascular complications
  • Violent or self-destructive behaviour in some cases

It’s not only the effects, but the mystery around the drug. The effects can vary massively between users due to unknown ingredients in each batch and unpredictable potency. It’s impossible to know what you are ingesting and how strong it is.

Can Monkey Dust Cause Psychosis?

Due to the effects of monkey dust on the brain, causing many psychotic symptoms, there is a belief that it can cause psychosis.

Substances can’t cause psychosis; however, monkey dust can trigger psychotic symptoms such as:

  • Severe paranoia
  • Delusions
  • Hallucinations
  • Disorganised thinking

If you have underlying mental health conditions or suffer from psychosis anyway, monkey dust can worsen the problem. Due to the erratic behaviour and disconnect from reality people can experience whilst on monkey dust, some users may require urgent medical or psychiatric intervention to ensure they are not a danger to themselves or others.

Can You Overdose on Monkey Dust?

Because monkey dust can include unwanted substances, be extremely potent and pair dangerously with other substances, overdose and acute toxicity are likely outcomes.

Monkey dust overdose symptoms include:

  • Chest pain
  • Hyperthermia
  • Seizures
  • Extreme agitation
  • Loss of consciousness
  • Cardiac complications

An overdose of monkey dust can be very dangerous. If you think you or someone else might be overdosing, it’s better to be safe. Seek emergency medical help immediately.

What Are the Long-Term Effects?

There are long-term monkey effects if you continue to abuse the drug.

  • Persistent mental health issues (depression, anxiety, heightened psychosis risk)
  • Decline in cognitive functioning (memory, decision-making, information processing)
  • Poor sleep
  • Decline in physical health (cardiovascular issues)
  • Breakdown in relationships
  • Impact on employment and daily life

Even if you come off monkey dust, persistent psychological difficulties such as paranoia, depression and psychosis may continue.

Can You Become Addicted?

Synthetic cathinones do carry an addiction risk. They have a quick half-life, with intense highs and a huge crash, which is why people find themselves repeatedly using.

The more you use a drug, the quicker you build a tolerance and need more to feel the same effects. Stimulants in particular foster a psychological dependence as they flood your brain with dopamine, hijacking your brain’s reward systems and creating a compulsive need to use the substance.

Repeated use of monkey dust can lead to:

  • Cravings
  • Compulsive drug-seeking behaviour
  • Loss of control
  • Continued use despite the negative consequences

What Are the Signs of Monkey Dust Addiction?

It’s important to know the signs of addiction so that you can act. If you don’t, the addiction can grow and eventually come to affect all areas of your life.

Signs of monkey dust addiction to watch out for include:

  • Frequent use
  • Obsessive focus on obtaining monkey dust
  • Financial issues
  • Neglecting daily responsibilities
  • Relationship problems
  • Mood swings
  • Withdrawing from normal activities
  • Becoming more secretive
  • Decline in work/school performance

What Happens During Withdrawal?

Common monkey dust withdrawal symptoms include:

  • Fatigue
  • Depression
  • Anxiety
  • Sleep disturbances
  • Irritability
  • Cravings
  • Paranoia
  • Hallucinations

Withdrawal from monkey dust will typically last for around a week. As you can see from the symptoms, it can be quite a difficult period, but the overall severity of these symptoms can vary.
