Does Morphine and Oxycodone test the same on drug test?

Does morphine and oxycodone test the same

To better understand how drugs are tested and does morphine and oxycodone test the same on drug test we need to look at the necessary factors. Each body is different, so each body will react differently. Some people take longer to digest and clear out drugs and some do it quicker. It is also important to know that drug testing devices often use different testing methods.

Morphine drug test use a standard drug testing method called OPI 300. These tests are most often depicted as testing strips which show results when they react with traces of a certain drug. Like most testing strips the standard OPI 300 model is a piece of highly reactive paper. The specific structure of the drug makes it react with the strips.

Oxycodone drug test can often show differing results and even false positives. This is because the common mistake when considering this drug is that it has the same structure as most other drugs. The truth is that Oxycodone has a slightly different structure and can confuse a drug testing strip if it is not constructed correctly.

Lifestyle factors when drug testing

There are several factors that influence how long a standard structure drug like Morphine will stay in your system. The half life of Morphine is within the range of 2.5 and 3.5 hours. A drug’s half life is how long a half dose of a drug takes to metabolize in a healthy person’s blood. This helps us determine how long a drug like Morphine will persist in your system.

The half life of Oxycodone is between 3 and 5 hours and traces of the drug can stay in your system for up to 13 days. The factors below also show how long a drug will stay in your system and what influences these changes. With oxycodone the most important ones are drug intake and metabolism.

There are several lifestyle factors that also influence how long drugs like Morphine and Oxycodone will stay inside your system.The factors range from body weight to frequency of drug intake and they all have different effects.  Knowing these factors will help you figure out if you are in danger and what steps to take.

Here are the factors:

  1. Personal height and weight – Your height and weight will play an important role in how fast a drug is metabolised because of the concentration of fat in certain parts of your body. Fat is a great storage unit for traces of drugs.
  2. General activity – Building up your metabolism on a regular basis is a good way to counter the effects of drug in the long term. Since being active and exercising builds up metabolism we couldn’t recommend it enough.
  3. Metabolism – A nicely built up metabolism is a cornerstone to both a healthy life as well as your drug clearing capability.
  4. Body mass and body fat – A high concentration of body fat in any area of your body will hold traces of drugs. Fat is usually a great storage place for drugs and this makes it harder to metabolise.

Other factors that may influence drug metabolization are:

  1. A person’s age – As people age, their metabolism gets slower. Elderly people will have quite the problem metabolising traces of drugs out of their system.
  2. Liver and kidney functions – The liver and the kidneys are the organs that metabolise drugs out of your system. In order to keep the process going, keep these organs healthy.
  3. Types of drugs – Metabolization depends highly on what kind of drugs you are taking in to your system. Different drugs produce different factors.
  4. Your drug intake – Depending on how often you take drugs and how large the overall dose is the metabolization time will be longer. If someone takes drugs regularly they can expect to be dealing with the drug in their system for some time.

If there is drug testing coming up at your workplace the best way to regulate traces of drugs in your system is to stop the intake of the drug. This will allow your body to clear up and metabolize all that it needs to provide a needed result.

Difference between Morphine and Oxycodone

When talking about Morphine and Oxycodone it is important to realise that these drugs are quite strong. Morphine is usually used to treat extreme pain and is used sparingly. This is because Morphine can cause severe addiction and it is quite hard to relieve yourself of this addiction. Morphine should be used only with a doctor’s supervision and with professional monitoring.

While it is also used to relieve extreme pain, Oxycodone is far more life threatening. The drug is known to cause severe breathing problems when a dose is changed or enlarged. Due to the sheer strength of the drug it has been known to cause a comatose state. Oxycodone can be life threatening for younger people and especially for children.

In the case of Morphine and Oxycodone we have different base structures for the two drugs. Does Morphine and Oxycodone test the same? Due to their differing structure different tests are needed to test for these drugs. In order to test for Oxycodone a special Oxycodone drug test is needed.


Both Morphine and Oxycodone should be taken very seriously, they are strong drugs that can threaten lives if not used as intended.Morphine drug tests work differently then Oxycodone drug tests. If you are looking for special drug testing devices for these drugs purchase drug testing devices for personal use. Testing for these drugs can be useful as it keeps you and your doctor informed on the levels of substances in your system. This can help keep you safe.

If you’re worried about your intake of Morphine or Oxycodone consider talking to a healthcare provider!
