Benzo misuse is a growing issue in Colorado, and many people who are misusing it combine them with alcohol to enhance the effects. When their tolerance to alcohol increases, people may use benzos to feel a euphoric experience.

In other cases, people may mix them simply because they’re taking benzodiazepines for anxiety and choosing to drink for social reasons. This is a common occurrence due to how widely alcohol is used as a social drug and how widely benzodiazepines are used for therapeutic reasons.

Regardless of the reason, alcohol and benzodiazepines have additive interactions due to the way these two substances affect the body, and mixing the two should be avoided.

Risk of Overdose

Both benzos and alcohol act as depressants to the nervous system. Using both together could depress the nervous system too much and cause breathing to slow down or stopOverdoses can easily occur when both benzos and alcohol are used together.

Overdoses can be fatal. If you believe an overdose is in progress, take immediate action by dialing 911 or the National Poison Control Center at 1-866-220-8570.

Impaired Movements or Reactions

Benzos and alcohol are commonly used together in date-rape situations to make people incapable of resisting the attack. Even if they are still conscious, those who take benzos and alcohol together may not be able to move, or the motivation to resist may not be present. These impairments could cause injury in other situations as well. For instance, if your location becomes unsafe, you may not have the ability or motivation to leave.

Memory Loss

The combination of alcohol and benzos interferes with your brain’s ability to form permanent memories. Misusing these together may result in short- or long-term memory loss that may have formed during substance misuse. You may not be able to remember events that occurred, as well as how or why they occurred.

Increased Aggression, Hostility, and Irritability

Not everyone experiences these effects, but if you do, you could end up ruining relationships or even getting arrested as a result of your benzo and alcohol misuse. While you may imagine that you benefit from the high benzos and alcohol give you, your friends and family may have an entirely different view of your behavior if you treat them with hostility or become abusive toward them during your misuse.

Potentially Deadly Withdrawal Symptoms

If you become dependent on a benzo and alcohol mix, it is dangerous to detox from this combo without medical supervision. This is because withdrawal can cause seizures that could be fatal if not treated medically. These risks make the combination of alcohol and benzos dangerous even for people who try to stop their misuse.

In a recent study by The Recovery Village, those who were detoxing from polysubstance abuse were:

  • 2.14 times more likely to experience Delirium tremens (DT)
  • 2.25 times more likely to experience seizures
  • 1.60 times more likely to experience hallucinations
