Identifying Propofol on the Street
Because of its distinct appearance and effects, propofol has several informal monikers that describe its character. The most common street name is "milk of amnesia," directly referencing the drug's sterile, milky-white emulsion and its powerful amnestic properties, causing users to forget the events surrounding its administration. Other slang terms that have emerged, particularly in discussions of recreational use, include "the milk drug" or "the white one". Among medical professionals, who have a disproportionately high rate of propofol abuse due to access, the term "dancing with the white rabbit" has been cited, alluding to the drug's euphoric effects.
What is Propofol Used For Medically?
Propofol is a rapid-acting, non-barbiturate sedative and anesthetic agent that is only intended for use under strict medical supervision. Its primary applications in a clinical setting include:
- Induction and Maintenance of General Anesthesia: Administered intravenously to put patients to sleep for surgical procedures.
- Procedural Sedation: Used during short, painful, or uncomfortable procedures, such as colonoscopies or endoscopies.
- Sedation in the Intensive Care Unit (ICU): Provides continuous sedation for critically ill patients, especially those on mechanical ventilation.
Its rapid onset of action and quick clearance from the body allow for a fast recovery time, which makes it ideal for outpatient procedures. However, this very characteristic is part of what makes it appealing to abusers, as it can allow them to function relatively normally shortly after use, potentially hiding their addiction.
Why is Propofol Abused?
Despite its lethal potential, propofol has a high potential for abuse due to its sought-after subjective effects. Research has shown that even at sub-anesthetic doses, propofol can increase dopamine levels in the brain's reward centers, much like other addictive substances. The reasons for misuse often cited include:
- Euphoria: Many users report feeling a pleasant or elated sensation.
- Stress and Tension Relief: For some, it provides a means of escape from stress or anxiety.
- Insomnia Relief: Medical professionals have reported abusing the drug to combat chronic insomnia.
- Hallucinations and Dreams: A percentage of patients report experiencing pleasant hallucinations or vivid dreams during sedation.
Because propofol is not a federally controlled substance, access is less regulated than for many other potent drugs, especially within hospital settings where it is routinely used and disposed of. This easy availability to healthcare workers, such as anesthesiologists and nurses, has led to a documented, and likely underreported, problem of diversion and abuse.
The Severe Dangers of Recreational Propofol Use
Recreational use of propofol is extremely perilous and frequently leads to death due to its narrow therapeutic index and potent effects on the respiratory and cardiovascular systems. Unlike other recreational drugs, there is no safe margin for error, and deaths from accidental overdose are common.
- Respiratory Depression: Propofol is a powerful respiratory depressant. Unmonitored administration can lead to apnea (cessation of breathing) and fatal respiratory arrest. This is often the cause of death in cases of overdose.
- Cardiovascular Effects: The drug can cause a significant drop in blood pressure (hypotension) due to vasodilation, which is especially dangerous in dehydrated or hypovolemic individuals.
- Propofol Infusion Syndrome (PRIS): A rare but potentially lethal complication in critically ill patients receiving high doses of propofol over an extended period. PRIS can cause severe metabolic acidosis, heart failure, kidney failure, and rhabdomyolysis.
- Addiction and Psychological Dependence: Repeated use can lead to psychological dependence and addiction, marked by intense cravings for the drug.
The high-profile death of musician Michael Jackson in 2009 brought public attention to the risks of propofol misuse, highlighting that even small doses administered without proper medical monitoring can be fatal.
Comparison of Legitimate vs. Illicit Propofol Use
| Feature | Legitimate Medical Use | Illicit Recreational Use |
|---|---|---|
| Environment | Controlled hospital/clinical setting | Uncontrolled environment (home, etc.) |
| Administrator | Trained anesthesiologist or medical professional | Self-administered or by an untrained person |
| Monitoring | Continuous, including heart rate, blood pressure, and breathing | None or insufficient monitoring |
| Equipment | Full access to resuscitation equipment (oxygen, ventilator) | No access to proper life-saving equipment |
| Dosage | Carefully calculated based on weight and health | Random, uncontrolled dosing, often in excess |
| Primary Goal | Induce anesthesia or provide sedation for a medical procedure | Achieve euphoria, stress relief, or combat insomnia |
| Main Risk | Allergic reaction, pain at injection site, transient apnea | Respiratory arrest, cardiac collapse, overdose, death |
Signs of Propofol Abuse
Recognizing the signs of propofol abuse is critical, especially among individuals with access to the drug. These signs can be subtle and are often masked due to the drug's short-acting nature.
Behavioral Signs:
- Increased isolation and secretive behavior.
- Unusual mood swings or irritability.
- Declining performance at work, particularly for healthcare professionals.
- Obsessive preoccupation with obtaining the drug.
Physical Signs:
- Finding injection-related paraphernalia such as syringes, needles, and empty vials.
- Wearing long-sleeved clothing to hide injection sites.
- Episodes of drowsiness or confusion.
- Slurred speech or unsteady movements.
- Withdrawal symptoms like tremors, nausea, or severe anxiety upon stopping use.
Conclusion: The Perils of Unregulated Propofol
While widely and safely used in a clinical context, the street name for propofol, "milk of amnesia," and other slang terms underscore its dangerous and addictive potential when misused. Its status as an unscheduled substance in many places, combined with its euphoric effects and rapid clearance, makes it a high-risk substance for diversion and abuse, particularly among those with easy access. The stark contrast between its controlled medical use and its deadly recreational potential highlights the need for vigilance. The ease with which a safe clinical tool can become a lethal substance in the wrong hands serves as a powerful reminder of the risks of unregulated drug use.
