Hair testing is a type of drug testing method that is capable of detecting a pattern of chronic or repeated drug use. It has the longest detection window of any type of drug test.
Demerol, a brand name for meperidine, can be detected in hair follicles for up to 90 days, or three months, on average. This is similar to the timeframe for other commonly used drugs.
What Is Demerol?
Demerol is a prescription pain reliever that belongs to a class of depressant medications known as opiate analgesics. It is chemically similar to opioids like fentanyl, methadone, and tramadol.
When taken, it binds to opioid receptors located in the central nervous system, which are involved in regulating physical movement, hormones, mood, and pain sensation.
When used, Demerol can cause:
- dry mouth
Demerol is prescribed for severe and chronic pain management. With chronic use, Demerol can be habit-forming and may lead to drug tolerance, dependence, and addiction with misuse.

- metabolic rate
- kidney and liver function
What To Know About Hair Drug Tests
First of all, styling, washing, or dying your hair won’t affect whether or not Demerol can be detected in a hair test.
Second, you can still test positive for Demerol use even after its short-term side effects have worn off.
Hair screenings can be performed in a clinical setting, such as a laboratory, or at home using a hair test kit bought online.
Either way, getting a result will require submitting a sample of hair from either the scalp or another area of the body, such as the armpit.
A negative test result can be available in as little as 24 hours after the sample is received. Confirming a positive test result can take up to 72 hours.
Why Are Hair Drug Tests Used?
Drug testing can be ordered by a healthcare provider, employer, or legal entity such as a judge either for routine testing or due to suspicion of drug misuse.
Signs of Demerol misuse can include:
- running out of prescriptions early
- changes in heart rate, blood pressure, or breathing
- psychological addiction to Demerol
- taking Demerol in ways other than prescribed
- taking Demerol with illicit drugs (e.g. heroin, cocaine)
- overdosing on Demerol
Although hair testing isn’t the most common method, it can be useful for detecting repeated patterns of drug use due to its long detection window.
Getting Treatment For Demerol Abuse And Addiction
One of the reasons people search for drug detection times is because they’re concerned about having their drug use found out. This can sometimes be a sign of drug abuse.
People who abuse Demerol may have trouble getting off of it due to physical dependence. Physical dependence on Demerol can cause withdrawal symptoms that are challenging to manage alone.
If you or someone you know is misusing Demerol, treatment is available. Demerol abuse is treatable through detox, medications for opioid use disorder, and behavioral therapy.
Millions of people abuse prescription medications like Demerol each year and struggle with addiction. If this is you, you’re not alone.
