Common Substances Used in Spiking and Their Effects

Understanding the Drugs Used in Spiking

When someone spikes a drink or administers drugs without consent, they may use a variety of substances to incapacitate, disorient, or exploit another individual. While the substances used can evolve over time, understanding the most commonly used drugs and their typical effects can help individuals recognise the signs of spiking, remain vigilant, and know when to seek help.

Commonly Used Substances in Spiking

Here are some of the substances most frequently reported in spiking incidents:

1. Alcohol

Though it may seem obvious, one of the most frequent ways to spike a drink is by adding extra alcohol. A drink that appears normal could contain significantly stronger spirits or a higher volume of alcohol, leading to unexpected intoxication, disorientation, nausea, and vulnerability.

2. Sedatives and “Date-Rape Drugs”

Several sedatives, often referred to as “date-rape drugs,” are used because they induce drowsiness, confusion, and memory lapses. Two well-known examples of these substances include:

• Rohypnol: Commonly called “roofies,” Rohypnol is a powerful benzodiazepine once prescribed as a sleeping aid and muscle relaxant. It can induce extreme drowsiness, blackouts, amnesia, and impaired motor control.
• Gamma-Hydroxybutyrate (GHB): A central nervous system depressant, GHB causes dizziness, euphoria, confusion, unconsciousness, and, at higher doses, respiratory distress. Its salty or soapy taste makes it difficult to detect once mixed into a drink.

3. Ketamine

Ketamine, originally developed as an anaesthetic, is often misused due to its dissociative and anaesthetic properties. In spiking cases, ketamine can make the victim feel detached from their body, disoriented, and defenceless. Victims may experience hallucinations, confusion, and an inability to respond coherently.

4. Benzodiazepines (Other than Rohypnol)

Other than Rohypnol, benzodiazepines like Valium (diazepam) and Xanax (alprazolam) are commonly used in spiking incidents. These drugs slow brain activity, causing drowsiness, slurred speech, impaired judgement, and memory problems. They dissolve easily in drinks and are relatively simple to obtain on the illicit market.

5. Opioids

Though less commonly reported, powerful opioids such as fentanyl and morphine may be used. These drugs cause heavy sedation and dizziness, posing a severe risk of respiratory depression, overdose, and death. Even tiny amounts can be dangerous, so immediate medical attention is critical if opioid involvement is suspected.

6. Stimulants

Stimulants such as cocaine or MDMA (ecstasy) are less frequently involved in spiking incidents aimed at incapacitating victims, but they may still be added to drinks or cigarettes. These substances can cause anxiety, confusion, and agitation. Victims may initially feel energised or hyperactive, but quickly lose control, leading to harmful responses such as a racing heart, overheating, or paranoia.

Recognising the Signs of Spiking and Taking Action

Understanding the substances commonly used in spiking and their effects can help individuals stay alert and respond effectively. If you suspect someone has been spiked, it's vital to act promptly and seek medical assistance if necessary. Early recognition and intervention can help protect victims from further harm.
