Factors That Can Affect Opioid Detection Times

Average time-frames for drug detection may not apply to everyone. The actual amount of time opioids stay in your system can depend on a range of factors.

Factors that can affect how long opioids stay in your system:

  • age
  • dose taken
  • type of opioid (i.e. short-acting vs. long-acting)
  • use of other drugs
  • frequency of use
  • drug dependence
  • metabolic rate
  • kidney and liver function
  • method of use
  • body composition (e.g. weight, height)

People who are opioid-dependent may be unable to stop taking opioids long enough to get them out of their system. If you are opioid-dependent, do not try to quit opioids cold-turkey.

How To Get Opioids Out Of Your System

If you’ve been taking opioids regularly, or have misused opioids, getting them out of your system will require a detox process.

Trying to stop taking opioids all at once by quitting cold-turkey can be dangerous. This can trigger highly uncomfortable withdrawal symptoms and pose other serious health risks.

For people addicted to opioids, the safest way to get off opioids is to begin a medical detox program.

Opioid Detox

Opioid detox programs can help people addicted to opioids stop their drug use under the guidance and supervision of medical professionals.

Medical detox programs can offer:

  • 24/7 medical supervision
  • medicine for withdrawal symptoms
  • hydration support
  • care coordination

Detoxing from opioids can last five to seven days on average. After this, additional treatment in an inpatient or outpatient substance abuse rehab program is highly recommended.
