This article discusses how long does heroin stay in your system. Below is a chart of the approximate retention times, by types of test. The time is provided in ranges due to individual and other factors that affect a test result, such as:
metabolism
dosage
frequency of use
overall health
liver function
sensitivity of test
age
kidney well-being
other medications
time elapsed since the last dose
purity
Age is a factor that can affect results. Younger people usually have a faster metabolism than older individuals, and it will typically clear more quickly. Genetics is also a factor. Some people have higher or lower enzymes that break it down, speeding or slowing down its elimination.
Factors like height and weight can affect the time it remains detectable. For example, a smaller, shorter individual is likely to retain it in their body slightly longer than a more prominent individual or someone overweight or obese.
Kidney and liver function also have an impact on removal. These are organs bearing most of the burden of metabolizing and elimination.
Detection Window
Approximate Time Range
Urine
2-4 days
Blood
Up to 12 hours
Saliva
1-3 days
Hair
Up to 90 days
Mode
The mode by which a person consumes this drug modestly impacts detox as well. Snorting it leaves behind fewer detectable breakdown products than smoking or injecting it. However, the metabolites created by smoking hang around in the body slightly more extended than after injection.
Morphine Table
When it is administered, this drug undergoes rapid metabolism in the body and is thereby converted into morphine, which is the primary active metabolite. The half-life refers to the time it takes for the concentration of the drug, or its metabolites, to reduce by half.
Drug Test
Detection Time
Urine
Occasional Use
Up to 2-3 days
Chronic Use
Up to 7-10 days or longer
Blood
Up to 24 hours or less
Saliva
Up to 1-2 days
Hair
Up to 90 days or longer
Cut
Dealers increase the batch’s volume with various substitutes, including fentanyl, sugar, caffeine, starch, baking soda, talcum powder, powdered pain meds, and even rat poison. These substitutes can affect the body and how quickly it clears. How potent it is and how much a person significantly affects how long it remains detectable.
