Key Takeaways
- Synthetic cannabinoids (Spice, K2) are not synthetic marijuana. They bind to cannabinoid receptors with far greater potency and can cause seizures, psychosis, kidney failure, and death.
- Bath salts (synthetic cathinones) are potent stimulants that can produce paranoid psychosis, violent behavior, hyperthermia, and cardiovascular collapse.
- Chemical compositions change constantly as manufacturers modify structures to evade legal restrictions, making potency unpredictable and health effects impossible to anticipate.
- There are no antidotes for synthetic drug overdoses, and treatment is limited to supportive care for symptoms as they present.
- Synthetic drug use is associated with higher rates of emergency department visits per user than almost any other substance category.
What Are Synthetic Drugs?
Synthetic drugs are laboratory-created substances designed to mimic the effects of controlled substances while using chemical structures that are technically distinct from the drugs they imitate. This structural modification historically allowed manufacturers to sell these substances legally as "herbal incense," "plant food," or "bath salts" labeled "not for human consumption," evading drug enforcement laws while producing psychoactive effects in users.
The two major categories of synthetic drugs are synthetic cannabinoids (sold as Spice, K2, fake weed, and numerous other brand names) and synthetic cathinones (sold as bath salts, flakka, and various other names). Despite marketing that implies natural or benign origins, these substances are fully synthetic chemical compounds manufactured in clandestine laboratories, primarily in China and Southeast Asia, and imported for sale through convenience stores, gas stations, head shops, and online vendors.
In Southern California, synthetic drug use has affected communities across the socioeconomic spectrum, with synthetic cannabinoid use particularly prevalent among homeless populations, adolescents seeking substances that evade standard drug testing, and individuals on probation or parole who are subject to urinalysis. Trust SoCal's treatment team in Orange County has direct experience treating individuals affected by both synthetic cannabinoid and synthetic cathinone use disorders.
Synthetic cannabinoids are not a safe alternative to marijuana. They are full agonists at cannabinoid receptors (marijuana contains a partial agonist), producing effects that are 2 to 100 times more potent. Severe adverse reactions including death have been documented with doses that would be considered modest for natural cannabis.
Synthetic Cannabinoids: Spice and K2
Synthetic cannabinoids are chemicals sprayed onto dried plant material and marketed as herbal smoking blends or sold as liquids for vaporization. The term "synthetic marijuana" is dangerously misleading because these chemicals are pharmacologically distinct from THC, the primary psychoactive compound in cannabis. While THC is a partial agonist at CB1 cannabinoid receptors, producing relatively mild effects with a built-in ceiling, synthetic cannabinoids are typically full agonists with no such ceiling, producing effects that can be catastrophically more intense.
The health effects of synthetic cannabinoid use can be severe and unpredictable. Acute effects include extreme anxiety, paranoia, hallucinations, tachycardia, hypertension, vomiting, seizures, and loss of consciousness. More serious complications include acute kidney injury, rhabdomyolysis, myocardial infarction, stroke, and death. In 2018, a contaminated batch of synthetic cannabinoids in Illinois caused a mass poisoning event affecting more than 150 people, with several deaths from uncontrollable bleeding caused by brodifacoum (rat poison) contamination.
The constantly evolving chemical composition of synthetic cannabinoid products means that there is no consistent product and no reliable dose. A package of Spice purchased one week may contain an entirely different chemical compound the next week, and the concentration sprayed onto the plant material is never uniform. This variability makes every use episode an unpredictable gamble with potentially fatal consequences.
Synthetic Cathinones: Bath Salts and Flakka
Synthetic cathinones are stimulant compounds chemically related to cathinone, a substance found naturally in the khat plant. Sold as "bath salts," "research chemicals," or "plant food," these substances produce stimulant effects similar to methamphetamine or cocaine but with additional unpredictable psychoactive properties that can include hallucinations, extreme paranoia, and violent agitation.
The most commonly encountered synthetic cathinones include MDPV, mephedrone, and alpha-PVP (the compound most associated with the street name "flakka"). Alpha-PVP gained national notoriety for producing a syndrome of extreme agitation, paranoid psychosis, superhuman strength, and bizarre, often violent behavior in users. Emergency departments in Southern California and throughout Florida reported cases of individuals requiring sedation by multiple paramedics and law enforcement officers.
The cardiovascular and neurological risks of synthetic cathinone use are substantial. Hyperthermia (dangerously elevated body temperature), tachycardia, hypertension, rhabdomyolysis, seizures, and cardiovascular collapse have all been documented. The psychological effects can persist for days after use, and some individuals experience prolonged psychotic episodes requiring psychiatric hospitalization. There is no specific antidote for synthetic cathinone intoxication, and treatment is limited to aggressive supportive care.
- 1Extreme agitation and panic that may last hours to days
- 2Paranoid delusions, hallucinations, and psychotic episodes
- 3Violent or erratic behavior disproportionate to the situation
- 4Hyperthermia with body temperatures exceeding 104-106 degrees Fahrenheit
- 5Tachycardia and dangerous elevation of blood pressure
- 6Rhabdomyolysis (muscle breakdown) leading to kidney failure
- 7Seizures and loss of consciousness
- 8Cardiovascular collapse and death
Why Synthetic Drugs Are Especially Dangerous
Several factors make synthetic drugs uniquely dangerous compared to traditional substances of abuse. The constantly changing chemical compositions mean that users can never know exactly what substance they are consuming, its potency, or its specific effects on the body. Drug checking services and standard toxicology panels often cannot identify the specific synthetic compound involved, complicating both harm reduction efforts and emergency medical treatment.
The lack of any quality control in manufacturing creates extreme variability in potency, even within a single package. Hot spots of concentrated chemical on plant material have been identified as the cause of overdose clusters where multiple users from the same batch experience severe reactions while others from the same batch are unaffected. This unpredictability distinguishes synthetic drugs from most traditional substances where dosing, while still risky, is somewhat more consistent.
The legal cat-and-mouse game between manufacturers and regulators has produced hundreds of distinct synthetic compounds, many of which have never been tested in any capacity for human safety. Each new compound represents an unknown risk profile, and the health effects may differ substantially from the compound it replaced. At Trust SoCal, we treat synthetic drug use disorders with the same evidence-based approaches used for other substance addictions while recognizing the unique medical monitoring these substances require. Call (949) 280-8360 for a consultation.
The American Association of Poison Control Centers reported that synthetic cannabinoid exposure calls, while declining from their peak, still represent thousands of cases annually. Many more cases likely go unreported because users may not know exactly what substance they consumed.
Treatment for Synthetic Drug Addiction
Treatment for synthetic drug addiction follows the same general principles as treatment for other substance use disorders, with additional attention to the medical complications unique to these substances. Medical stabilization is the first priority, including assessment and management of any cardiovascular, neurological, renal, or psychiatric complications from recent use.
Behavioral therapies including cognitive behavioral therapy, contingency management, and motivational interviewing form the foundation of treatment. Because many synthetic drug users are young adults, treatment approaches may incorporate age-appropriate engagement strategies and address the social and environmental factors that facilitated access to synthetic substances. Family involvement is often critical, particularly for adolescent users.
