Harmful Effects of Mixing Benzodiazepines and Amphetamines

Benzodiazepines and amphetamines are 2 widely prescribed medications with distinct pharmacological effects. However, combining these drugs can lead to dangerous and harmful effects on various aspects of physical health, cognition, behavior, and mental well-being. Mixing benzodiazepines and amphetamines can also lead to substance dependencies and substance use disorders, as well as increased risks of overdoses and death.

Why Do People Combine These Substances Together?

There are several reasons why people may choose to mix benzodiazepines and amphetamines despite the potential harmful effects. The primary reason is the desire to simultaneously experience the calming effects of benzodiazepines and the stimulating effects of amphetamines. Some individuals may seek a balance between relaxation and increased energy in order to enhance their productivity or performance in various activities.

Others may mix these drugs due to an incorrect perception that they can amplify their desired effects. For instance, some individuals with ADHD might believe that combining amphetamines with sedatives can offset unwanted side effects like restlessness or anxiety caused by stimulants alone.

Additionally, some users experiment with speedballing for recreational purposes, seeking a heightened euphoric sensation or intensified high. This combination can create a unique and potentially desirable experience, especially when seeking to prolong the effects of 1 drug by counteracting potential “come-downs” with another.

Short-Term Effects of Mixing Benzodiazepines and Amphetamines

The stimulating effects of the amphetamine provide increased energy, alertness, and euphoria, while the sedative effects of the depressant counteract anxiety and promote relaxation. Users may believe this combination provides the best of both worlds by simultaneously experiencing increased stimulation and decreased negative side effects.

Some common short-term effects of mixing benzodiazepines and amphetamines include:

  • Cardiovascular stress: Amphetamines increase heart rate, blood pressure, and vasoconstriction, while benzodiazepines have a depressant effect on the cardiovascular system. This contrasting impact can lead to increased strain on the heart, potentially resulting in irregular heartbeat or even cardiac arrest.
  • Respiratory suppression: Both benzodiazepines and amphetamines can cause respiratory depression on their own. When used together, they can further suppress breathing function, leading to shallow or labored respiration and potentially causing oxygen deprivation.
  • Sedation/over-sedation: Benzodiazepines are known for their sedative properties that promote relaxation and drowsiness. Combining them with stimulant-like amphetamines may mask fatigue signals from the body, leading an individual to overexert themselves without realizing it.
  • Impaired judgment: The mix of these drugs can significantly impair cognitive functions such as decision-making abilities, coordination skills, and reaction times. This can increase the risk of accidents or engaging in risky behaviors.
  • Mental health effects: Mixing benzodiazepines and amphetamines can have a negative impact on mental well-being. It may enhance feelings of agitation, anxiety, irritability, and panic attacks and may induce hallucinations or psychotic symptoms.

Long-Term and Serious Effects of Mixing Benzodiazepines and Amphetamines

Long-term and serious effects of mixing benzodiazepines and amphetamines can be severe and potentially life-threatening. For starters, there is an increased risk of addiction. Both benzodiazepines and amphetamines have a high potential for dependency, but when combined, the risk is even greater. Mixing these drugs alters brain chemistry and can lead to a more rapid development of tolerance, dependence, and addiction.

Next, cardiovascular complications can occur from sustained use of this drug combination. It could contribute to long-term cardiovascular issues such as hypertension (high blood pressure), arrhythmias (irregular heartbeat), heart disease, or stroke. Another long-term effect is cognitive impairment. Prolonged use of benzodiazepines combined with amphetamines may result in cognitive decline over time. Memory problems, decreased attention span, impaired learning abilities, and difficulty with problem-solving are some potential long-term consequences.

Prolonged use of these substances can result in impaired mental health as well. Mixing these substances increases the risk of developing or exacerbating mental health disorders such as anxiety disorders, depression, and mood swings. Additionally, chronic use can place significant stress on organs like the liver, kidneys, and respiratory system. Long-term use of benzodiazepines can lead to liver damage or failure, while amphetamines may cause kidney damage.

Furthermore, there is an increased overdose risk. Mixing benzodiazepines and amphetamines significantly increases the likelihood of an overdose. These drugs have opposite effects on the body, making it difficult for individuals to recognize their limits and properly gauge their intake.

An overdose can result in respiratory failure, coma, or death. In severe cases, long-term mixing of benzodiazepines and amphetamines can also lead to central nervous system failure. This can manifest as seizures, delirium, or even irreversible damage to the brain.

How Rehab and Detox Can Help

Rehab and detox programs play a crucial role in helping individuals overcome the harmful effects of mixing benzodiazepines and amphetamines. They provide medical supervision in a safe environment where withdrawal symptoms can be monitored and managed effectively. In situations where there are intense withdrawal symptoms, medication-assisted treatment may be appropriate. 

In addition, individuals have access to counseling and therapy to help start the recovery process. This may also include peer support group sessions and relapse prevention planning. By providing a structured environment coupled with evidence-based treatments, these interventions increase an individual’s likelihood of sustained sobriety.
