There are a few measures to take, some are simple and some are a bit, more difficult. Well, first thing’s first. Don’t give away yourself with obvious symptoms such are caughing, symptoms of chronic bronhitis and frequent catchig colds, your tester surely knows about them. And also take care of your personal look: clothing, hygine and your own appearance, I am not saying that you aren’t already doing that.
This won’t help you with the actual test, but will at least soften or mislead your tester a bit. What is more important is to think rational, you might have taken a few joints last night, but that doesn’t stop people to go to work or on college in the morning, does it? As a user you surely know the lenght of time in which drug traces remain in your blood and urine. If we put aside period of three years in which traces are present in your hair root, period for organism is a lot shorter.
Depending on your metabolism, the THC remains in your organism from 3 to 30 days, sometimes even to 45 days. So if you are tested for marijuana, your test will be focused on searching for THC. This ingridient also leaves traces in your brain, liver, fat tissue and kidneys. By using home-based urine test, acute use can be detected 2 to 3 days back while chronic can be traced 3 to 6 days back. If you expect to be tested on marijuana and are not sure if enough time elpased for traces to disappear from your metabolism, there are a few things you could do. Drink a lot. Drink teas, water, juices, alchohol might be a bad idea, take a lot of liquids, as much as you can but sugar-free. This is useful for removing traces from your urine where they remain longer than in blood.
Next, sweat a of Go jogging, running, practicing sports, doing exercises… but keep in mind to take care not to overload if you are a long-time drug user. So the more you sweat the more you will evict that from you. If your test is sooner you could do a few things to cheat. You could ‘borrow’ someones test sample if you think you could exchange it with yours or you could turn to medicine. If you do a small research you could find legal drugs in a pharmacy that contain THC and use it as a decoy, or you could buy active coal pills there and drink a few with water. Hope this was helpful.
