A few words on each type of the test.
Blood test
Good news
Active chemicals like THC does not hang out in your blood for a long time. The blood test tells how much weed you’ve used at the moment of the test, not detects long-term using. Because of its high cost and difficulties to get a sample blood test for cannabis is rarely performed.
Bad news
Drivers under the influence, persons on rehab programs, workers with strict requirements have to be careful. A possibility for them to be tested is high. If you have a few hours prior the test, just do it.
Saliva test
Good news
As THC leaves the blood fast and can be detected in saliva in short time frame. As a blood test saliva, one shows up the presence of active chemicals in your body at the present moment. And the main thing — saliva test is the easiest drug test to pass. Test your sample first.
Bad news
The popularity of saliva test grows up. It’s cheap enough, easy to perform, the result is ready in seconds. And you can’t change the sample. Watch your back.
Urine test
Good news
You can use somebody’s clean urine or a synthetic one. Traces of marijuana metabolites appear in urine in a few hours, so, in theory, if you forced to give a urine sample right now after the first joint in your life, you’ll most likely pass. In real life, it’s rare situation, so take the preventive measures.
Bad news
THC urine test is the most popular, cheap and informative. While THC stored in body fat, it stays in urine for a few days, for some “weed-rookie” until during the whole week and more. For single usage, in average, detection period is 2-3 days, but if you have excessive weight, it becomes longer. Remember about second-hand smoking and avoid weed smokers in closed areas. Increase your chance to pass.
Hair test
Good news
To find THC in hair after the single joint is doubtful, so don’t worry. There are not enough THC in your blood to passed on your hair. Such tests confirm regular and occasional using. But if you doubt, protect yourself prior the test.
Bad news
Only one joint is not danger. But how many of us can stop on one? Occasional using weed after 5-7 days can be detected by hair testing. You can fail the test during at least 3 months.
Remember about it when next time decided to enjoy a puff.
