Narcotics are drugs that are used to relax the brain, relieve pain, and induce sleep. They have an average half-life of about 3 to 5 hours and can remain present in the body for many days for patients with accommodating systems. It is important to note that there are different types of narcotics, some of which are long-acting, which means they are likely to remain in the blood for a longer period of time. Traces of narcotics can be detected in the urine, blood, hair, and saliva within two hours of use. Learn about the half-life of narcotics, how long they last in the body, and how to fully flush them out of the system.
Learn About Narcotics Half-Life:
How Long Do Narcotics Stay In The System?
Narcotics react similarly to the bodyโs receptors; however, the duration of their stay in the system can vary. Depending on individual factors such as age, rate of metabolism, and body mass, narcotics can remain in the system for as long as three days. Long-acting narcotics can remain as long as four days, depending on the dose and the frequency of use. Examples of narcotics that are long-lasting include:
- Fentanyl patch (Duragesic)
- Methadone (Dolophine)
- Morphine (Kadian)
- Oxycodone controlled-release (OxyContin)
Narcotics On The Drug Test
The detection of narcotics via a drug test depends on how much time has passed since taking the drug, the amount of substance, frequency of use, individual metabolism, and other factors. For prescription narcotics like oxycodone, hydrocodone, codeine, morphine, they can be detected within 33-54 hours of use. Schedule 1 narcotics like heroin, can be detected within 15-44 hours after consumption.
Urine Test
It is difficult to determine how long narcotics stay in the urine due to individual factors that play a major role. However, they should remain in the urine between 1 to 4 days. Well-hydrated patients have higher chances of excreting toxins a lot faster than less hydrated individuals. Narcotics like heroin, morphine remain in the urine for 1-2 days, while methadone remains in the urine for 2-3 days.
Blood Test
Just like urine, it is difficult to specify how long narcotics will stay in the blood due to the individual differences. Generally, they should remain in the blood for between 6 to 72 hours. During this period, they can be easily detected by a blood test. For narcotics like methadone, it can be detected in the blood after 30 minutes of use and remains in the blood for 2-3 days. Fentanyl, on the other hand, remains in the blood for around 12 hours.

Hair Test
Narcotics remain in the hair follicle for as long as 90 days. During this period, doctors can easily detect traces of them in the hair. To successfully carry out the test, a patientโs hair must be at least 0.5 to 1.5 inches. A person with shorter hair will need to supply more hair for the sample. Unlike saliva, blood, and urine tests, a hair drug test detects regular and long-term drug use. Fentanyl and methadone can remain in the hair for more than 90 days.
Flushing Narcotics From The System
There are various ways to hasten the elimination of narcotics from the system. Listed below are some of the ways that may speed up the process of elimination these drugs out of the system, however, they wonโt take the drugs out of the system completely due to a high potency of these medications.
Medical detox remains the most recommended and effective method to use, and it must be done under the supervision of medical specialists.
Cut The Source
For someone trying to flush narcotics from the body, the first step to take is to stop consuming. Cut off any access to them. By so doing, the body begins the process of shedding toxins accumulated during previous use. The sooner the source is cut, the faster the body flushes it out.
A medical specialist only should define the suitable schedule of decreasing drug use gradually.
Hydration
Staying hydrated is an effective way to speed up the elimination process. Prolonged use can result in dehydration, which lay host to some significant side effects of narcotics. Hence, patients must consume water regularly. Doing this helps to remove chemicals and toxins from the body through the urine. Herbal teas, fruit juices, and vegetable juices may also help remove toxins from the system faster.

Eat Healthy Food
Eating healthy food is another effective way to flush narcotics out of the body. Patients might also need to avoid sugary foods and fatty foods in general, so the body works on burning off fats it already has, instead of producing new ones.
Exercises
The need for constant activities cannot be overemphasized. When someone exercises, the body heats up, causing the body to sweat. Sweating helps to eliminate unhealthy toxins through the skin pores. By engaging in exercises, the body fights narcotics sedating nature, which tries to limit physical activities.
Sauna
Sauna is another effective way to eliminate these substances from the body. Through sauna bathing, the body excretes massive amounts of perspiration, resulting in the removal of unwanted waste products from the body.
Even though effective, saunas are not safe for everybody. A person with cardiovascular disease should speak to a doctor before trying out this method.
Eliminate Narcotics From The System Safely
It is highly recommended to avoid tapering off these medications without supervision of medical specialist, stopping to take them cold turkey or using any substances that are supposedly designated for self-detoxification, as this may lead to severe consequences.
Narcotics are potent drugs, and removing these drugs from the system should be done under the supervision of medical specialists.
Their use for a time, longer than prescribed or with exceeded dose may lead to the rapid development of drug tolerance and addiction. For a patient that is already addicted, enrolling for medical treatment in a rehab facility is the way to go. There are numerous rehabilitation centers available to choose from in the U.S.
