Even though synthetic urine is the most popular way of passing a urine drug test, we still get a lot of emails with ‘I have a drug test in 2 days, I’m x tall and weigh x pounds, smoked a joint 2 weeks ago, should I use synthetic urine? Does synthetic urine work?’.
To clear the picture and put some common sense thinking into does synthetic urine work for lab drug tests, we did a bit of investigating which uncovered the following conclusions:
Does synthetic urine work for:
- Calibrating urinalysis test strips – it was created to check if urine drug tests work properly – YES.
- ‘Golden showers’ – synthetic urine does work for that but some people complain about the lack of ‘that unique smell’ – so partly yes.
- Passing a urine drug test (the big one everybody wants to know about) – of course, it works if you use it with common sense – so YES.
We focused on the question if synthetic urine works to pass a drug test, even in 2017. From user reviews and, well, our own experience we are quite certain that it works (otherwise it wouldn’t be so frequently used by one-time puffers and true stoners alike to beat a drug test).
What is even more important than knowing if synthetic urine works is which is the best one to use to guarantee you to pass. We’ll go into that but here’s a spoiler – it has everything to do with the right temperature of synthetic urine.
How Does Synthetic Urine Work?
Despite synthetic urine being widely used to beat drug tests, it was initially designed to test if urinalysis test strips work consistently or not.
Basically, they mixed together all the things that they measure with a urine test (such as urea and uric acid) to create perfect healthy urine – otherwise known as ‘synthetic urine’. Then they checked if urine test strips will recognize the synthetic urine as perfect healthy urine – and out of 100 tests, 100 test strips told the same. There is no difference between synthetic urine and normal urine.
Of course, when drug testing for employment began, people started using synthetic urine to beat the drug test. Test strips dipped into a cup of normal urine and the best synthetic urine (2023) show exactly the same result.
What makes synthetic urine work is, of course, that it is toxin-free. If you smoked weed in the past few weeks, test strips dipped in your pee will recognize THC and you’ll get ‘THC-positive’ on your medical record. Ups!
Now, if you would put synthetic urine in the cup instead of your urine, the test strips dipped in it would tell the lab techs it’s a healthy urine. Does it include THC? Nope, it’s clean and you get ‘drug-free’ on your medical record. Quite simple, right? That’s the basics of how does synthetic urine work for lab tests.
Let us have a look when synthetic urine doesn’t work:
The Only Case When Synthetic Urine Doesn’t Work For Urine Drug Test
Almost any synthetic urine will show up as a clean healthy urine on the urinalysis test strips. However, there is one case when people don’t pass a drug test when using synthetic urine (and they have to redo the test).
»The Cold Urine« Case
Everybody using common sense will be able to pass a drug test with the right synthetic urine. What some omit is that for synthetic urine to really work, they have to heat it up.
Don’t get me wrong: the test strips and lab results will always be fine as in ‘drug-free’ urine. The only problem is if the lab tech who usually collects the cups of urine picks up your urine sample and it’s cold.
Your own urine would come from your bladder and would have body temperature (about 98-102 F). In order to pass a drug test with synthetic urine, you have to heat it up. If the lab tech will feel that urine temperature is any other than body temperature, he or she will probably know what’s up. And even then, you will only be asked to redo the test – so another urine sample.
Luckily, with a bit of common sense, there is a simple solution to cold urine – just heat it up!
How To Heat Up Synthetic Urine So That It Does Work Every Time
There are actually two options for how to do that – the easy one and the hard one.
I’ll start with the hard one:
Microwave it for 10 seconds and then, somehow, keep it warm. I have to honestly say that because of this technique of heating it up people still ask ‘does synthetic urine work’. Why?
Because sooner or later you’ll find someone who overheated the synthetic urine and the lab tech figured out this molten-lava hot urine couldn’t possibly come from a human being.
We also, of course, have some geniuses who don’t heat it at all and are asked to redo the test again (this time with their urine).
Believe it or not, synthetic urine producers thought about how to easily heat up synthetic urine so that it does work consistently. One actually did figure it out and even patented their formula. Here is the link to the patent, if you’re interested:
The easy heat up comes in a vial containing a special chemical that, when poured into the synthetic urine, heats it up exactly to 98-102F (you even get an indicator that turns green when the urine is in the right temp. range).
The synthetic urine that comes with the self-heat up vial is called Sub-Solution synthetic urine and it’s pretty much the most recommended synthetic urine to use for drug test exactly because of the easy heat-up.
Thus it is no wonder that ‘The Sub’ won the #1 rank as the best synthetic urine of 2017. Here is the list of top 7 synthetic urines currently on the market:

Here’s also a first-hand story of a guy who used it and answers pretty well if synthetic urine does work:
You’ll Pass A Drug Test With A Bit Of Common Sense (No Worries)
With synthetic urine, a guy flipping burgers at Mcdonald’s or a rocket scientist can pass a drug test. Just don’t be stupid about it – synthetic urine does work but you have to heat it up to exactly the body temperature.
Of course, you can microwave it and risk getting caught, or you can buy Sub-Solution and just pour the vial into the ready-to-go synthetic urine.
Just don’t let that one joint you had a few weeks ago ruin your future, especially because even if weed is legal, the drug testing laws are still enforced and that’s simply irrational.
