Polysubstance Abuse Treatment

Contact Apex Recovery for More Information on Rehab in Tennessee

a person talks to a therapist during polysubstance abuse  treatmentWhen people abuse drugs or alcohol, it is not a choice based on an organized spreadsheet of pros and cons or a systematically pursued life course. No one sets out to become addicted or damage their health. There are many reasons people dabble in recreational drugs or alcohol, and the path to addiction is not a straight line. For example, it is very common for substance abuse to be used as a way to self-medicate—to mute symptoms of anxiety, depression, or PTSD. Polysubstance abuse—the abuse of more than one substance—is common, especially among those who have a co-occurring mental health condition. When abusing multiple substances leads to addiction, the risks greatly increase. Professional substance abuse treatment is the most effective and safe way to begin recovery from a polysubstance addiction.

What Is Polysubstance Abuse? 

The dependence on multiple substances taken in combination is known as polysubstance abuse. Becoming addicted to more than one substance can happen in a few different ways: 

  • You are already dependent on one substance and begin to experiment with others to change, improve, or amplify the effects of the original substance. 
  • Your drug and alcohol use is indiscriminate, and you experiment with different combinations seeking the high you desire—or maximum relief from painful mental health symptoms. 
  • You intentionally combine two drugs, such as an opioid with cocaine, known as a speedball, to create specific effects and be able to prolong a binge cycle. 

These are risky behaviors, even without considering the risk of addiction. If you or someone you love is taking these kinds of risks with multiple substances, consider that the behavior alone is cause for concern and a reason to get mental health and substance abuse support and treatment. 

Risks of Polysubstance Abuse

Polysubstance abuse risks include: 

  • Suppressed breathing 
  • Heart attack 
  • Brain damage 
  • Seizure 
  • Organ failure 
  • Psychosis 
  • Overdose 
  • Death 

Whether someone is getting up in the morning with meth and unwinding at the end of the day with oxycodone, mixing alcohol with cocaine, or alternating benzodiazepines with MDMA, their body and brain are under even greater assault than they would be with just high doses of one of those substances. If someone ends up in the emergency room with an overdose but cannot be sure what they took, treatment is that much more challenging. 

Polysubstance Abuse Treatment at Apex Recovery Nashville

Polysubstance abuse and addiction are more difficult to treat than an addiction to a single substance. In many cases, individuals abuse substances without knowing exactly what they are or what they have taken over time, leading to challenges in helping with withdrawal.  

A polysubstance abuse rehab is the safest place to begin recovery under the care of a team of medical and therapeutic professionals who work together to provide coordinated, evidence-based care. 

People with polysubstance abuse often have co-occurring mental and physical conditions and thus qualify for inpatient rehab, with the option to step down into outpatient rehab if desired. In any case, your treatment plan will be created thoughtfully and with full information about your medical and addiction history by a team of providers and discussed in detail with you so you understand and are fully onboard with the plan.

Fred Bowen

Founder & Board Member

Fred was raised in San Clemente, California. Fred was exposed to the drug culture at a very early age. By the time Fred had graduated from high school, his addiction had progressed to a point that most people do not return from. For another decade, he struggled with addiction and recovery with multiple attempts at abstinence. There were periods of homelessness along with periods of high functioning and experiencing success. Fred realized, ultimately, that addiction was always in control. At the age of thirty, on death’s door, Fred had hit rock bottom and had a moment of clarity that would save his life. That clarity was the sea of change in his life.

20 years later, Fred is not able to recognize his past life in comparison to where he is now. Early on, Fred had made the decision that addiction and recovery would be his sole vocation. He started sober living homes and found that working with people that suffered from the same addiction would be his passion. This was the beginning of Apex Recovery.

“I’m extremely proud of the person I have become simply by staying clean and having an open mind in regards to the recovery process.”

Fred’s hope for anyone suffering the way he did is to be able to find a way out of the vicious cycle of addiction. Recovery is a gift that all are entitled to. Apex can be a part of that.
