In 2023, 69% of Ohio's 4,452 fatal overdoses involved multiple drugs, particularly the combination of fentanyl and other substances. Some people combine different drugs on purpose, but many have no idea that what they are taking is actually a dangerous mixture.

If you are using more than one drug, or you have lost someone to what turned out to be a deadly combination, we will explain what polydrug addiction really looks like and how Armada Recovery can help.
Key Takeaways
- Most fatal overdoses in Ohio now involve more than one substance.
- Fentanyl contamination means many people are exposed to opioids without realizing it.
- Polydrug addiction increases overdose risk due to unpredictable drug interactions.
- Mixing stimulants and depressants places extreme stress on the heart and lungs.
- Recovery requires treatment that addresses all substances at the same time.
What Is Polydrug Addiction?
Polydrug addiction is when you have become addicted to more than one substance.
This might mean you deliberately use multiple drugs together, such as:
-
Mixing cocaine with ecstasy on a night out
-
Taking benzodiazepines to come down from stimulants
But it can also mean you are unknowingly taking drug combinations because of contamination in the drug supply.
| Drug Combination | Number of Deaths (2023) | Percentage of Total Overdoses | Key Takeaway |
|---|---|---|---|
| Fentanyl + Cocaine | 1,379 | 31% | Cocaine users are at extreme risk due to widespread fentanyl contamination. |
| Fentanyl + Methamphetamine | 971 | 22% | Mixing stimulants with opioids dramatically increases overdose unpredictability. |
| Fentanyl + Benzodiazepines | 275 | 6% | Combining depressants greatly raises the risk of fatal respiratory failure. |
| Cocaine Deaths Involving Fentanyl | — | 79% | Most cocaine-related overdoses now involve fentanyl, often unknowingly. |
| Methamphetamine Deaths Involving Fentanyl | — | 77% | Fentanyl has deeply penetrated the stimulant drug supply. |
Fentanyl and Ohio’s Drug Supply
In Ohio, fentanyl has spread widely through the drug market. In 2023:
-
79% of cocaine-related overdose deaths also involved fentanyl
-
77% of methamphetamine-related deaths involved fentanyl
-
73% of benzodiazepine-related deaths involved fentanyl
Many people had no idea fentanyl was present in the drugs they were taking. This makes polydrug addiction especially dangerous, increasing the risk of unpredictable effects and unintended addiction to substances you never meant to use.
What Are the Signs of Polydrug Addiction?
Polydrug addiction can be harder to recognize than single-substance addiction because different drugs can mask or alter each other’s effects.
Common warning signs include:
-
Using one drug to counteract or enhance the effects of another
-
Needing multiple substances just to feel “normal” or get through the day
-
Withdrawal symptoms that don’t match what you thought you were taking
-
Unpredictable reactions or side effects that change from one use to the next
-
Mixing prescription medications with alcohol or street drugs
-
Using stimulants during the day and depressants at night
-
Physical symptoms suggesting multiple drugs, such as drowsiness and a racing heart
-
Erratic behavior that doesn’t fit a single drug pattern
-
Overdose scares or sudden “bad reactions”
How Does Polydrug Addiction Develop?
Polydrug addiction can begin in several ways, but it usually follows a progression from occasional use into dependence and eventually addiction.
Polydrug Abuse
Polydrug abuse may start intentionally or accidentally.
Examples include:
-
Drinking alcohol with cocaine to “take the edge off”
-
Using benzodiazepines to sleep after stimulant use
Unintentional polydrug use can happen when:
-
Drugs are contaminated
-
One substance stops working and another is added
Polydrug Dependence
Polydrug dependence often follows quickly.
Each drug changes the brain differently:
-
Opioids reduce natural painkiller production
-
Stimulants disrupt dopamine regulation
When multiple substances are involved, the brain adapts to all of them. Stopping one drug while continuing another can trigger unexpected and confusing withdrawal symptoms.
Polydrug Addiction
At this stage, stopping becomes extremely difficult—even when the harm is obvious.
You may:
-
Try to quit one substance and increase use of another
-
Relapse on all substances when attempting sobriety
-
Feel trapped in a cycle you can’t control
Polydrug Addiction and Overdose in Ohio
In 2023:
-
Fentanyl + cocaine caused 1,379 deaths (31% of all overdoses)
-
Fentanyl + methamphetamine caused 971 deaths (22%)
-
Fentanyl + benzodiazepines caused 275 deaths
Additional data:
-
79% of cocaine-related deaths involved fentanyl
-
77% of methamphetamine-related deaths involved fentanyl
What Causes Polydrug Addiction?
Polydrug addiction is driven by the same brain changes as single-substance addiction, but the causes are often more complex.
Common contributors include:
-
Using one drug to manage side effects of another
-
Chasing a specific high that requires multiple substances
-
Drug supply contamination
-
Using whatever drug is available
-
Self-medicating multiple symptoms (energy, anxiety, sleep)
-
Escalating tolerance to one drug
-
Social environments where mixing drugs is normalized
-
Underlying mental health conditions
What Are the Dangers and Side Effects of Polydrug Addiction?
Mixing substances multiplies the risks of each individual drug.
Serious dangers include:
-
Fatal overdose (especially opioids + depressants)
-
Unpredictable drug interactions
-
Seizures or cardiac events
-
Respiratory failure
-
Liver and kidney damage
-
Extreme cardiovascular strain
-
Dangerous withdrawal requiring medical supervision
-
Increased risk of psychosis
-
Memory loss and cognitive impairment
-
Severe mental health decline
-
Higher accident risk
-
Greater difficulty achieving long-term recovery
