Mixing Benzos and Cocaine – Is it Safe?

mixing benzos and cocaineCocaine is a dangerously addictive drug that acts as a stimulant, increasing heart rate and blood pressure, raising body temperature, helping to keep a person awake, and heightening alertness, focus, and attention.1

Benzodiazepines, often called benzos for short, are a class of central nervous system depressants that are regularly prescribed to treat anxiety and panic disorders, muscle spasm, seizures and insomnia, and to aid in the management of alcohol withdrawal symptoms. Certain physiological functions under central nervous system control, like heart rate, blood pressure, respiration, and body temperature, may be slowed and lowered by benzos.2

 In general, the pharmacological effects of cocaine and benzos are quite different. Cocaine is an “upper” while benzos are “downers.” The combination of these two substances can have unpredictable adverse effects.

Interaction of Benzos and Cocaine on the Brain

Connecting with Treatment

Cocaine is a short-acting drug that markedly impacts the activity of dopamine in the brain. Dopamine is one of the brain’s neurotransmitters instrumental in movement and reward. Artificially elevated levels of dopamine activity can create an intense and euphoric high.1

According to the 2015 National Survey on Drug Use and Health (NSDUH), close to 15 percent of Americans aged 12 and older have reported abusing cocaine at some time in their lives.3 A cocaine high does not last very long and is often followed by a significant “crash.” During this crash, an individual may feel fatigued, hungry, depressed, and both physically and mentally sluggish. These feelings may encourage a person to continue using more of the drug, often in a “binge” pattern.4 The intensity of the cocaine high and subsequent crash may also entice a person to take another drug like a benzodiazepine to “smooth” out some of these significant “comedown” effects.

Benzodiazepine drugs like Xanax (alprazolam) and Valium (diazepam) increase the activity of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). This chemical messenger reduces brain cell excitability, thus increasing relaxation, relieving muscle tension, and lowering anxiety levels.2

These drugs are commonly diverted and misused nonmedically, as they can also create a mellow high when abused. The 2014 NSDUH indicated that nearly 2.5 million American adults had misused prescription sedative or tranquilizer drugs at the time of the survey.5 In addition to nonmedical misuse on their own, benzos are commonly used concurrently with other substances, such as alcohol or stimulants.

Benzodiazepines may be combined with a stimulant drug, like cocaine, in an attempt to counteract some of their sedative effects, helping a person to stay awake longer and have more energy. Individuals may also mix cocaine and benzos in order to enhance or prolong a euphoric high. This practice is highly dangerous, however, as the combination of stimulant and depressant drugs can significantly impact brain chemistry, which can have numerous short-term and long-term consequences.6

Potential Risks of Combining Cocaine and Benzos

Though the two drugs are commonly viewed as having somewhat opposite physiological effects, overdose remains a risk when misusing both cocaine and benzodiazepine drugs. Drug overdose deaths continue to rise in the United States, as the Centers for Disease Control and Prevention (CDC) reports that between 2000 and 2015, over a half-million Americans lost their lives to a drug overdose.7

Drug overdoses commonly involve more than one drug. Polydrug abuse can increase the potential side effects of all drugs involved and make an overdose more difficult to treat.6

Some signs and symptoms of a cocaine overdose include:

  • Dangerously high blood pressure.
  • Racing pulse and irregular heart rate.
  • Sweating and high body temperature.
  • Nausea and vomiting.
  • Mental status changes, such as profound confusion.
  • Agitation.
  • Tremors.
  • Psychosis.

Stimulants like cocaine can mask some of the effects of CNS depressants, such as benzodiazepines. Therefore, a person may be more likely to take too much of the benzodiazepine, increasing the risk of overdose. In 2013, benzodiazepine drugs were the second most common class of prescription drugs involved in overdose deaths; 30% of all prescription drug overdose fatalities involved a benzodiazepine drug.8

Signs of a benzodiazepine overdose may include:

  • Confusion.
  • Slurred speech.
  • Sluggish movements.
  • Difficulty walking.
  • Abnormal eye movements.
  • Respiratory depression.
  • Being cold to touch and having a bluish tinge to the lips, skin, and nails.
  • Over-sedation and trouble staying awake.
  • Loss of consciousness.

There may be additional possible interactions and overdose side effects when multiple drugs are involved, and it becomes difficult to isolate how multiple drugs may impact each individual. This can complicate overdose reversal attempts as well.

Combining cocaine and a prescription benzodiazepine can raise the potential for drug dependence, a complicated withdrawal syndrome, and addiction development.1,10

The method of use can lead to additional issues as well. For instance, someone who snorts drugs increases the risks of damaging the nasal and sinus cavities while a person who smokes drugs can damage their lungs and experience respiratory problems. Injecting drugs can lead to a host of potential hazards, including collapsed veins, skin infections, and a heightened risk for contracting an infectious disease like hepatitis or HIV/AIDS.11

Increased Rate of Addiction

Cocaine and benzodiazepine drugs both have reinforcing properties due to their interaction with our brain reward centers. Additionally, they have dose-dependent mind-altering effects, which can increase the likelihood of bad decisions, poor judgment, and out-of-character behaviors. Abusing these drugs can increase a person’s risk for accidents, injuries, as well as aggressive and even potentially violent behavior. Benzos can impair memory as well, so a person may have difficulties remembering things that happen while they are under the influence.6

Both benzos and cocaine are addictive substances. The manner in which cocaine is taken, often in a binge pattern, increases its addictive potential as well, as does taking multiple drugs at the same time.

Over 8 percent of adults in America battled addiction in 2014, the Substance Abuse and Mental Health Services Administration (SAMHSA) reports. Addiction is a brain disease that has physical, emotional, and social ramifications, and it is characterized by difficulties controlling or stopping drug use.12

With repeated drug use, the brain stops working as it did before and instead relies on the drugs to remain balanced. This is drug dependence, and a major side effect of dependence is the onset of difficult withdrawal symptoms and cravings when the drugs wear off. Significant mood swings, difficulty feeling pleasure, impaired cognitive abilities, and physical discomfort are all possible side effects of benzodiazepine and cocaine withdrawal. Appetite and weight fluctuation as well as trouble sleeping are additional issues associated with cocaine and benzodiazepine addiction and withdrawal.10

Cocaine and benzodiazepines may be taken to enhance moods and ease stress, but they can actually end up compounding possible mental health concerns. SAMHSA reports that around 8 million adults in the United States struggle with co-occurring mental health and substance use disorders. Substance abuse can interfere with treatment and recovery of a mental health disorder and vice versa. Adding in more than one drug can further complicate matters.12

It is important to disclose all drugs that are being taken before entering into a treatment program in order to ensure that all possible interactions are accounted for. Much of the time, a drug test is done along with an assessment to determine the proper type and level of care.

Benzodiazepine drugs are not to be stopped “cold turkey” without professional help, as the associated withdrawal symptoms can be severe and even life-threatening. A medical detox program can aid in safely allowing these drugs to be cleared from the body using a tapering schedule, sometimes with the aid of a longer-acting substituted benzodiazepine agent. In the case of polydrug abuse, medical detox is an optimal first level of care. After professional detox and successful withdrawal management, individuals can then enter in to an integrated treatment program that can promote recovery from all co-occurring medical and mental health disorders and drug abuse concerns.13
