There are two major categories of synthetic drugs most often seen in emergency rooms and addiction treatment programs: synthetic cannabinoids and synthetic cathinones.(Source)

Both are created in laboratories to act on the same brain receptors as other drugs, but with altered chemical structures. These changes are often made to avoid detection on drug tests or to temporarily skirt drug laws, not to make the substances safer.

In the United States, many of these chemicals are now controlled under federal and state law, and the Drug Enforcement Administration (DEA) regularly adds new synthetic compounds to the list of Schedule I substances because of their high potential for abuse and lack of accepted medical use.(Source) However, manufacturers frequently tweak the formulas, creating new versions faster than regulations can keep up.

Despite increased enforcement, some synthetic drugs are still sold in gas stations, smoke shops, convenience stores, and online. They may be packaged as:

• “Herbal incense”
• “Potpourri”
• “Plant food”
• “Research chemicals”

To get around regulations, labels often say “not for human consumption,” even though the products are clearly marketed for people to use. For someone struggling with substance use, these warnings can be easy to ignore.(Source)

Cannabinoids are chemicals that act on the same brain receptors as THC, the main psychoactive compound in cannabis. Synthetic cannabinoids are lab‑made chemicals designed to stimulate these receptors, often much more strongly than natural cannabis.(Source)

Synthetic cannabinoids are usually:

• Sprayed onto dried plant material and smoked
• Sold as liquids to be vaporized and inhaled in e‑cigarettes or vape pens

They are sometimes marketed as:

• “Synthetic marijuana”
• “Fake weed”
• “Herbal incense”

Brand names have included K2, Spice, and many others, but the specific chemicals inside a package can vary widely from batch to batch. Because these products are unregulated and often produced in illegal labs, users rarely know exactly what they are taking or how strong it is.(Source)

Synthetic cathinones are stimulants chemically related to cathinone, a substance found in the khat plant. They are designed to mimic the effects of drugs like amphetamines, cocaine, and MDMA (ecstasy). These drugs are often sold as white or brown crystalline powders and may be swallowed, snorted, smoked, or injected.(Source)

Synthetic cathinones are commonly sold as “bath salts,” “plant food,” or “research chemicals.” They are not the same as Epsom salts or products used for bathing. The term “bath salts” is simply a marketing label used to disguise their true purpose.

These substances can cause intense stimulation, euphoria, and increased sociability—but also severe agitation, paranoia, and violent behavior. Emergency departments across the U.S. and worldwide have reported serious medical and psychiatric complications linked to synthetic cathinone use.(Source)

Bath salts are not the only synthetic cathinones. Other examples include:

• Mephedrone (often called “Meow Meow” or “MCAT”)
• Methylone
• Other designer stimulants with changing street names

Krokodil is sometimes mentioned alongside synthetic drugs, but it is a different type of substance (a homemade opioid derived from codeine) and not a cathinone.(Source)

Because formulas change frequently, two products with the same street name may contain completely different chemicals and strengths. This unpredictability greatly increases the risk of overdose and long‑term harm.

Synthetic drugs can cause a wide range of physical and psychological side effects. Because they are often much more potent than the natural drugs they imitate, even small amounts can lead to severe reactions.(Source)

Common risks across many synthetic drugs include:

• Rapid or irregular heartbeat
• High blood pressure
• Chest pain
• Extreme agitation or aggression
• Confusion and disorientation
• Hallucinations and paranoia
• Seizures
• Suicidal thoughts or behavior

In severe cases, synthetic drug use can lead to stroke, heart attack, kidney failure, or death.(Source) The risk is especially high when these substances are snorted or injected, or when they are mixed with alcohol, opioids, or other drugs.

Researchers continue to study how synthetic cathinones affect the brain, but current evidence shows that they act on the same systems involved in reward, mood, and movement as other powerful stimulants.(Source)

Synthetic cathinones can cause:

• Paranoia
• Hallucinations
• Panic attacks
• Increased talkativeness or friendliness
• Increased sex drive and risk‑taking
• Extreme agitation and restlessness
• Violent or unpredictable behavior

Physically, these drugs may lead to:

• Elevated heart rate and blood pressure
• Chest pain and shortness of breath
• Sweating and overheating
• Muscle breakdown (rhabdomyolysis)
• Kidney damage or kidney failure

Cases of severe intoxication, especially with snorting or injection, have been linked to seizures, organ failure, and death.(Source)

Synthetic cathinones can be highly addictive. Animal studies show that laboratory animals will repeatedly self‑administer certain synthetic cathinones, similar to how they respond to cocaine or methamphetamine.(Source) People who use these drugs often report intense cravings and a strong urge to keep using, even after experiencing serious negative consequences.

Someone trying to stop using synthetic cathinones may experience withdrawal symptoms such as:

• Depression
• Anxiety
• Tremors
• Insomnia or disturbed sleep
• Paranoia and irritability

These symptoms can make it difficult to quit without support. Professional treatment can help manage withdrawal safely and address the underlying emotional and behavioral patterns that drive continued use.

Public attitudes toward cannabis have changed significantly in recent years, and legal cannabis is now available in many states. This can create a false sense of safety around synthetic cannabinoids, which are sometimes marketed as a legal or harmless alternative. In reality, synthetic cannabinoids are often far more dangerous than natural cannabis.(Source)

These products are frequently sold in colorful foil packets or small bottles, sometimes under brand names like K2 or Spice. For years, they were easy to find in smoke shops, novelty stores, gas stations, and online. Although many specific chemicals have since been banned, new versions continue to appear.

Because the chemicals used in synthetic cannabinoids have no accepted medical use and a high potential for abuse, many are classified as Schedule I substances under U.S. law.(Source) Manufacturers attempt to stay ahead of regulations by constantly altering the chemical formulas.

Synthetic cannabinoids have been especially popular among some young people and individuals trying to avoid positive drug tests, because older testing methods did not always detect these substances. Newer drug tests can identify many synthetic cannabinoid compounds, but not all of them.(Source)

Since these products are manufactured without quality control, the dose and ingredients can vary widely, even within the same brand. This unpredictability is a major reason why synthetic cannabinoids are so dangerous.

Synthetic cannabinoids can cause both short‑term and long‑term health problems. In many cases, the effects are much more intense and dangerous than those associated with natural cannabis.(Source)

Reported side effects include:

• Agitation, aggression, anxiety, and paranoia
• Nausea and vomiting
• Tremors or muscle twitching
• Rapid heart rate (tachycardia)
• High blood pressure
• Hallucinations and delusions
• Dilated pupils
• Seizures
• Suicidal thoughts or behavior

Emergency departments across the U.S. have treated thousands of patients for serious complications related to synthetic cannabinoid use, including psychosis, heart problems, and kidney injury.(Source)

Research on synthetic cannabinoids is ongoing, but we know that many of these chemicals bind much more strongly to cannabinoid receptors in the brain than THC does. This can produce extremely powerful and unpredictable effects.(Source)

Because the exact chemical composition of most synthetic cannabinoid products is unknown—and may change frequently—users cannot reliably predict how a given dose will affect them. Even experienced users can suddenly experience severe reactions from a new batch.

People who have used synthetic cannabinoids report effects such as:

• Elevated mood or euphoria
• Relaxation or sedation
• Altered perception of time and surroundings
• Symptoms of psychosis, including hearing or seeing things that are not there
• Disorganized or delusional thinking

Psychotic effects can include:

• Extreme anxiety or panic
• Confusion and disorientation
• Intense paranoia
• Hallucinations and loss of contact with reality

In some cases, these symptoms can last for days or weeks and may require hospitalization. There is concern that synthetic cannabinoids may trigger long‑lasting mental health problems, especially in people who are already vulnerable to conditions like schizophrenia or bipolar disorder.(Source)

Synthetic cannabinoids can harm both physical and mental health. Many people who use these substances end up in emergency rooms due to severe side effects.(Source)

Reported health effects include:

• Rapid heart rate and palpitations
• Vomiting and severe nausea
• Violent or unpredictable behavior
• Suicidal thoughts or attempts
• Confusion and memory problems
• Kidney damage in some cases

Although synthetic cannabinoids may sometimes produce a relaxing or euphoric high, the risk of experiencing intense paranoia, confusion, and psychosis is much higher than with natural cannabis.(Source)

Synthetic cannabinoids can also be addictive. People who use them regularly may develop tolerance (needing more to get the same effect) and experience withdrawal symptoms when they try to stop, such as:

• Headaches
• Anxiety and restlessness
• Depression or low mood
• Irritability and sleep problems

Some synthetic cannabinoid compounds may stay in the body longer than THC, and the long‑term effects of repeated exposure are still not fully understood.(Source)

Clinicians sometimes use the term “spice‑induced psychosis” to describe severe hallucinations and delusions linked to synthetic cannabinoid use. These episodes can resemble schizophrenia and may put the person and others at risk of harm.(Source)

Anyone can develop a problem with synthetic drugs, but certain groups appear to be at higher risk.

Teens and young adults

National surveys show that synthetic cannabinoids and cathinones have been used by adolescents and young adults, often because they are perceived as “legal” or safer than other drugs.(Source) Teens aged 12–17 and young adults may be especially vulnerable because:

• They are more likely to experiment with substances
• Products are marketed in colorful, youth‑oriented packaging
• Misconceptions about safety are common
• Peer pressure and curiosity can be strong

Some synthetic cannabinoid products have been found to be many times more potent at cannabinoid receptors than THC, which can dramatically increase the risk of overdose and psychosis.(Source)

People in recovery from other substances

Individuals recovering from addiction to heroin, methamphetamine, cocaine, or alcohol may be drawn to synthetic drugs as a perceived “safer” or undetectable alternative. In reality, these substances can:

• Trigger powerful cravings
• Undermine recovery progress
• Lead to relapse on other drugs

Because synthetic drugs are unpredictable and often stronger than expected, a single use can quickly escalate into renewed addiction.

People involved in the criminal justice system

Synthetic drugs have been reported as a significant problem in some correctional settings, partly because they may be harder to detect on standard drug tests and can be smuggled in small quantities.(Source) Incarcerated individuals may use these substances to cope with stress, trauma, or boredom, increasing the risk of addiction and mental health crises.

Underlying risk factors

Across all groups, certain factors increase the likelihood of developing a synthetic drug use disorder:

• Family history of addiction
• Co‑occurring mental health conditions (such as depression, anxiety, PTSD, or bipolar disorder)
• History of trauma or chronic stress
• Lack of social support or stable housing

Understanding these risks can help families and providers intervene earlier and connect people to effective treatment.

Because synthetic drugs are highly potent and chemically unpredictable, overdose is a serious and ongoing concern.(Source)

Signs of a possible synthetic drug overdose may include:

• Severe agitation or aggression
• Chest pain or difficulty breathing
• Seizures
• Loss of consciousness
• Very high heart rate or blood pressure
• Extreme confusion, paranoia, or hallucinations

If you suspect an overdose, call emergency services immediately. Do not wait to see if the person “sleeps it off.” Rapid medical care can be lifesaving.

Once the person is medically stabilized, comprehensive addiction treatment is often the next crucial step. Many people who use synthetic drugs also use other substances or live with co‑occurring mental health conditions such as depression, anxiety, or trauma‑related disorders.(Source)
