Drug Testing FAQS-how long after last drug use will a drug test be positive ?

 drug testing kit

How long do drugs stay positive in your system ?

The amount of time drugs stay in the body depends on many factors such as, the amount of the drug taken, its strength, purity, the body weight of the person being tested and rate of metabolism, and whether they are a casual user or a long term user.

Cut offs for onsite drug testing kits are brand specific and as a guide the window period for drug detection using saliva or oral fluid drug test are shorter than comparable urine drug test.

As a rough guideline most drugs  (excluding cannabis will be detectable on a urine drug test for up to 3-4 days) and on a saliva drug test for up to a maximum of 72 hours (some saliva tests are only up to 24 hours)

Cannabis can be detected in some individuals on a urine drug test for up to 28-30 days (depends on individual useage and body fat composition as Cannabis metabolites stored in body fat)

Cannabis Detection Times in Urine & Saliva

Heavy, or one off / occasional use ?

Cannabis is fat soluble, so over sustained regular use it is deposited around the body and can take several weeks, too a month to be excreted. In practice this only occurs in heavy regular consumers of cannabis, usually the concentrated forms such as skunt, and for most irreglular or occassioanl users THC will be excreted much quicker.

Most instant saliva drug tests will only detect THC for only 24 hrs after use. Most Cannabis urine drug tests will detect use for between 3 and 5 days after use.

The saliva drug test kits currently detect at 12ng/ml THC Cannabis
All urine instant tests cut off at 50ng/ml while lab confimations normally test to just 15ng/ml

Instant urine tests will mainly detect for 3-5 days after light use. For tests to remain positive longer than 5 days suggest either heavy previous use, or re-exposure.
