Gabapentin (Neurontin) belongs to a class of drugs called anticonvulsants. Both gabapentin and cocaine are addictive substances that have the potential for abuse. Though mixing gabapentin and cocaine does not usually cause any life-threatening responses, it can result in a greater chance of addiction and increase the risk of overdose.

These substances can cause serious symptoms including seizures and respiratory depression when mixed.

Why Do People Mix Cocaine And Gabapentin?

Gabapentin has long been thought to be a safe medication with no potential for abuse, but recent findings suggest otherwise. Not only does gabapentin have abuse potential on its own, but people who take gabapentin are also likely to abuse it with other drugs, such as cocaine. Abusing more than one substance at a time increases risks and side effects, and there are several reasons a person might abuse cocaine and gabapentin together.

The Euphoric High Caused By Polysubstance Abuse

In a study conducted in 2018 on people who use drugs in Appalachian Kentucky, researchers found a pattern of gabapentin abuse. The participants in this study said that they used gabapentin in combination with drugs, including cocaine, in order to produce CNS effects.

A few of the desired effects from combining gabapentin and cocaine include:

  • muscle relaxation
  • pain reduction
  • sleep induction
  • feeling drunk
  • feeling “high”

Mixing these drugs can result in extreme euphoria similar to the effects of ecstasy. Gabapentin can also mask some of the unwanted side effects of cocaine, resulting in a more sedate euphoric experience.

Low Cost Of Gabapentin

Gabapentin is a relatively low-cost drug, which contributes to its popularity. Many people may substitute gabapentin for opioids as a cheaper alternative. A person can mix gabapentin with drugs like cocaine to experience a high without spending as much money on other, more expensive drugs.

Effects Of Mixing Cocaine And Gabapentin

Cocaine and gabapentin affect the brain through different mechanisms, creating unpredictable interactions when combined. Cocaine stimulates dopamine pathways causing euphoria and increased energy while stressing the cardiovascular system, whereas gabapentin alters brain electrical activity and neurotransmitter function to reduce pain and seizure activity.

When used together, gabapentin’s sedating effects may mask cocaine’s stimulating properties, leading users to consume dangerous amounts of cocaine to achieve their desired high. This combination increases overdose risk while impairing judgment and coordination, creating heightened dangers of accidents, poor decision-making, and life-threatening cardiovascular complications.

Are There Any Risks With Mixing Cocaine And Gabapentin?

Any time people abuse mind-altering drugs, there are risks involved. Mixing cocaine and gabapentin can result in serious and, in some cases, fatal outcomes.

Risk Of Addiction

The biggest concern in mixing these substances is the potential for abuse. Cocaine is a widely abused substance, and gabapentin is gaining popularity as a drug of choice for abuse. Mixing these drugs to create a more intense high can quickly lead to an addiction.

Increased Chance Of Overdose

Overdoses involving gabapentin and cocaine can result in life-threatening consequences, including death. While there have only been two reported deaths resulting from gabapentin abuse alone, the chance of fatal overdose increases significantly when cocaine and gabapentin are mixed.

Both cocaine and gabapentin overdoses can cause serious and life-threatening effects, such as:

  • diarrhea and vomiting, which can cause severe dehydration and lead to death
  • seizures
  • decreased muscle coordination
  • respiratory depression

The combination of these substances creates a medical emergency that requires immediate professional intervention, as the overlapping symptoms can rapidly progress to organ failure or death. Anyone experiencing signs of overdose from this drug combination should call 911 immediately, as the unpredictable nature of these interactions makes it impossible to safely manage overdose symptoms without emergency medical care.

Getting Help For Cocaine And Gabapentin Misuse

Abusing cocaine and gabapentin together creates a complex addiction that requires professional support to overcome safely. Because both substances affect the brain differently, each carries its own withdrawal risks, including intense cravings and depression from cocaine and potentially dangerous seizures from gabapentin. Attempting to detox from both at once without medical supervision significantly increases the risk of serious complications and relapse.

Professional treatment programs are equipped to handle polysubstance addiction through medically supervised detox, behavioral therapy, and relapse prevention planning.
