• Notes developed from the following sites can be used on the test. You must have your own notes in your own handwriting. Your notes will be attached to your test answer sheet.
     
    site #1:    http://www.thegooddrugsguide.com/cocaine/drugtests.htm
     
    1. When are the following drug types detectable in saliva, urine, and hair AND how long is each detectable:
     
                                           cocaine, heroin, marijuana
     
    site #2:    http://addiction.lovetoknow.com/wiki/How_Long_Does_Heroin_Stay_in_Your_System
     
    (in case you have problems getting on the site, here's the article....the questions are below the article)
     
     Heroin in the Body

    Heroin is an opiate. Opiates enter your blood stream easily and will accumulate in fat tissue. Drugs that remain in fat tissue will continue to enter the blood stream slowly over time. This is why you may feel the high from opiates longer than other drugs. However, this also means that your system holds on to the drug longer, but it doesn't always show up on drug tests.

    Hair Follicles

    While a urinalysis is the most popular way to test for drug use, testing hair follicles is also increasing in popularity because of its ability to detect heroin use after many months. The reason for this is that many drugs, especially heroin, will remain in the hair for up to three months, according to ExpoMed.

    Urine

    Generally, heroin can show up on a urine test for as little as two and half hours or as much as two days, according to MedlinePlus. However, heavy users can fail a drug urine test for as long as seven days.

    Blood

    Blood tests are another way to detect drug use, but it's the least reliable. Many opiates, like heroin, leave a person's blood stream within 6 hours, according to a drug treatment center.

    Saliva

    Saliva also has a short detection time. After consumption of an opiate, Alain G. Verstraete from Yale University reports it could take only 5 hours to be undetectable, but for some people, it may take up to 48 hours. It takes longer for it to be undetectable when the person has been using heroine for a while, and has taken a large dose.

    Factors that Affect the Duration of Drugs in Your Body

    The above lengths of time that it takes for heroin to leave a person's body are averages. Every individual is different and certain factors influence how long the drug stays in the body:

    • Height
    • Weight
    • Metabolism
    • Amount of consumption
    • Quality of drug
     
    1. What factors affect the duration of drugs in the body?
