A blood drug test is likely the most accurate of all four THC tests, provided it’s it is administered within its detection time.
However, it is also the rarest test of them.
How can this be?
The answer is simple. The blood test is the most expensive, period. It is also the most invasive type of drug screening.
Therefore, you’ll likely never be compelled to give your blood for THC testing purposes, unless the stakes are high regarding money or legal consequences. Sometimes a blood test for drugs is ordered by insurance companies.
But since it will happen to some of us, I’ll go through what you need to know for the best chances of passing one.
The blood test looks for the actual drug substance rather than its metabolites (products after your body breaks it down), as is what for example urine tests target. It also only reveals the toxin contamination levels in your body right at the time of the test (hair tests go back in time).
One big positive to blood tests from a stoners perspective is the detection time. It is rather short. Generally less than two days for a one time use or 3-4 days at tops. For a regular user it’s generally less than 7 days or perhaps a little longer if you’re a very heavy smoker.
So still this is nothing like the months of possible detection time of hair and even urine tests.
How to Pass a Blood Drug Test
As you may know by now, I prefer to minimize the risks.
Therefore, to pass the blood test it’s best if you abstain any cannabis consumption for a week. If you smoked weed the same week of the test, my advise would be to clear your system with some Toxin Rid. The 3-day detox should be sufficient here, but if you have more time than that then go with a longer detox. Safety comes first.
However, if you’re a chronic/regular/heavy user, I suggest that you either abstain for 2 weeks+ (the more the better) or go through a 7 or 10-day Toxin Rid detox in the period before your test. This should pretty much clear your blood of THC.
On the day of the test, use the Sure Gel method which you can find out all about here. This is best practice no matter how much you’ve been smoking.
Exercising, eating well, staying hydrated and getting enough sleep is always helpful before any drug test, with the exception of hair drug tests where it doesn’t really matter. See here for more information on the healthy habits to adopt before your drug test. In short, a healthy body can be considerably more efficient at detoxing and in this case breaking down THC into its metabolites (The blood test screens for THC and not its metabolites, remember?).
Note that these are very safe guidelines and that it is still definitely possible to pass a blood test without any kind of detox efforts even if you smoked just three or even two days back. Many have done that (some have failed that as well). It is risky though, and not something I would try myself.
If you smoked the same day as your blood test, chances are you’re actually screwed. It’s not as simple with blood tests as with some of the other ones where you can use things such as a mouth wash/gum, fake pee or a detox drink and have a decent chance of passing.
Your best bet here is going for the above mentioned Sure Gel detox.
Legal adulterants aren’t really an option druing a blood test and are also very easy to detect. In other words, if you attempt cheating that way, they’ll likely know about it.
