Everyone knows that a person can fail a drug test for consuming marijuana. A lot of people are surprised to find out that you can also fail a drug test for being around too much second hand marijuana smoke (for an article about that, click this link here). A scientific study was recently conducted which found that even breaking up marijuana can result in a failed drug test. Per Culture Magazine:
A recent study conducted in Germany proves that even something as simple as breaking up cannabis and having residue on your fingers can cause a failed drug test.
This study was conducted by the University of Freiburg. The science behind the idea was simple: ten participants had to role one joint a day, and take a urine test every day. The study showed that by the middle of the study, most of those involved tested positive for THCA and THC, and four weeks after the test, the THC levels were still noticeable when hair was tested. This means that a month after touching cannabis, you can still test positive in some ways for the substance.
It takes quite a bit of marijuana handling to fail a drug test, but it is definitely possible, as proven by this case study. This is very significant for people that work in the cannabis industry, but think they can still pass a drug test because they don’t consume marijuana. People that are on probation or are required to be involved in some type of diversion program are who I think of off the top of my head. If you handle marijuana too much, you will absorb THC via your hands. Moral of the story – make sure to wear quality gloves if you have a need to handle a lot of cannabis but also need to pass a drug test.
