DOT drug tests really aren’t different than any other kind of drug test. I hear from a fair number of people who have to take them, worried that they’re harder to pass. But the only thing that makes them different is the fact that the requirements for a DOT drug test are set at the federal level.

What Is A DOT Drug Test?

For those who may not know, DOT stands for ‘Department of Transportation’. People who have to take a DOT drug test include anyone who drives a large truck or bus for a living, and any workers who are remotely involved with those vehicles – which is basically anyone in the same company.

A federal agency called the Federal Motor Carrier Safety Administration (FMCSA) has about a hundred pages of regulations that both employers and labs have to follow when administering DOT drug tests. But fortunately, most of those regulations simply cover the details about the paperwork that has to be done. The drug tests themselves are basically carried out just like they are for any other employer. Which doesn’t mean you shouldn’t take them seriously – it just means that you don’t have any extra cause for concern just because you’re taking a DOT drug test as opposed to any other kind.

Does The Dilution Method Work For DOT Drug Tests?

Since the FMCSA requires that a DOT drug test be a urinalysis, then yes, dilution will work fine. At least, it will be if you happen to be a pot smoker.

You’ll be given a standard 5-panel test that looks for other toxins as well, so if you do more than just smoke pot you’ll need to be aware of their detection periods and plan accordingly.

For most other drugs besides weed, detection periods are measured in days, not weeks. THC cannabanoids are kind of in a class by themselves because of the way they’re stored in the body (in your fat cells), which is why marijuana use can be detected so much longer than other drugs.

What’s The Best Way To Pass A DOT Drug Test?

For a routine piss test, federal law doesn’t require you to be observed. So you can dilute, as long as you do it CORRECTLY. When you do it right, you’re genuinely able to give a clean, ‘undiluted’ specimen right on the spot.

Of course you could also substitute, as long as you have access to clean pee and you’re able to keep it at the right temperature. You might also be able to use synthetic urine, which is mostly reliable.

But a few labs are able to detect certain ‘markers’ in synthetic urine that give it away. It’s a cat & mouse game that is always changing, so you just never know. Which is why I recommend that you use a ‘real powdered urine kit’ instead, if you can get your hands on one. It’s literally real human urine, and as long as the temperature is in the right range it’s a guaranteed pass.

HOWEVER – if you’ve recently failed a test, or if you’re coming back to work after being off because of an accident or something like that, then your drug test WILL be supervised.

For DOT Drug Tests, There Are Two Problems With Using Dilution

Federal regulations don’t require on-the-spot random tests for DOT tests. So most DOT employers schedule routine drug tests, and you don’t have to worry about being randomly tested. But if you happen to work for a real jerk who prefers to surprise his employees, then you’re in trouble.

Dilution won’t work in a situation where you aren’t given at least a couple hours notice. In that situation, I hate to say it but you’re pretty much screwed. I sure wish I could invent a magic pill that would help pot smokers pass on a minute’s notice, because I’d be a millionaire.

Another situation where you might be screwed is if you’re being RE-TESTED. This one is hard to predict, because it depends on the individual circumstances in your case. But there’s always a chance that for a re-test, your specimen will be tested at a much lower tolerance level, 15ng/ml instead of 50ng/ml.

Unless you stopped smoking for at least a few weeks prior, then it will be virtually impossible to dilute enough to get your metabolite levels below a 15ng/ml cut-off.

But USUALLY, if you’re being asked to give a whole new specimen, then it means you’re going to be tested at the higher tolerance level first…

So What’s The Take-Away?

First, you’d better hope and pray that your DOT drug test is scheduled, and not random. If it’s a routine test and you know you won’t be observed, then substitution is definitely worth considering. And if you have a scheduled test that even might be supervised, then you can dilute, but in that situation the chances are slightly higher that you’ll be tested at the lower tolerance level of 15ng/ml.

Urine drug tests are a fact of life today, whether you are applying for a new job or joining an athletic organization. Most people will have to take a drug test at one point or another in their life. Although you may be the most qualified and skilled individual for a specific position, the company or organization can still refuse to accept you based on activities within your personal life. While most people would agree that drug testing is an invasion of privacy, the practice is not going to disappear anytime soon. So you may as well learn how to effectively prepare yourself in case you’re required to pass a urine drug test.

Urine Drug Tests – Why You Should Be Particularly Concerned About Them

While there are other forms of testing, the type that you will almost always face is a urine drug test. The process is very straightforward. Once your organization informs you that you need to submit to a drug test, you will have to visit a drug testing laboratory within their specific window of time. After submitting a sample of your urine to the laboratory, it will be checked for the presence of opiates, marijuana, methamphetamines, cocaine and amphetamines. Most every drug besides marijuana leaves your system within a few days to a week, so urine drug tests are of particular concern to pot smokers. Evidence of marijuana use can linger in your body for up to a month.

Once the laboratory has finished its analysis, your organization will receive a report showing whether you tested positive or negative for each substance. In some cases the lab will give you the results of your urine test before sharing them with your employer. If you fail your test for any reason, even if you have never used drugs in your life, be warned that you face an uphill battle proving your innocence.

Detection Periods For Urine Drug Tests

When faced with a drug test, many people first try to figure out how long marijuana stays in your system, and how long they need to stay clean. Although a quick Google search will return tens of thousands of websites with detection time tables, every single one is simply an estimate. Factors such as usage frequency and the composition of your body all play a role in the length of the detection period. This means your detection period could be significantly different from someone else in a similar situation. No two people will be exactly alike when it comes to figuring out whether or not you’re clean enough to pass a urine drug test.

The only 100% guaranteed way to pass a urine drug test is with some form of substitution. You can either substitute with the urine of someone you know (as long as you know they’re clean), or you can use real powdered urine. Of course, substitution is difficult if your drug test is supervised, but for some people it’s worth the risk. After substitution, the next most reliable way to pass a drug test is dilution. Dilution involves drinking a large volume of water on the day of your test, and then taking supplements that will hide the fact that you’re diluting from the lab. If done properly dilution has a success rate of around 99%, so it is still considered very reliable.

The Last Resort for Passing a Urine Drug Test

There are also many commercial detox drinks on the market that are touted to help someone pass a drug test. Their effectiveness rate is much lower than either substitution or the home dilution method, although some people swear by them. The bottom line is that if you need to pass a urine drug test, examine all your options and then make the choice that seems right for your situation.

Tips in passing a drug test are everywhere on the Internet, but unfortunately most of them are written by someone wanting to sell you detox products. Did you know that virtually all drugs besides marijuana are out of your system within just a few days? Yep. Only weed has such a long detection time, so that’s the reason why smokers need realistic tips in passing a drug test more than anyone.

Anyway, someone who bought my e-book recently is – get this – a lab supervisor who actually used to oversee drug testing. He’s a smoker who had to take a drug test himself for a job offer at another lab. Talk about ironic. So I thought to myself, who better to ask for tips in passing a drug test from?? He was open to the idea of letting me interview him via chat, so that I could post it on my blog. It turned out to be pretty long, so I decided to post it in two parts. You can read the rest of this interview at Tips in Passing a Drug Test – Part II.

JOHN: Well you get right to the point don’t you, lol. That’s a fair question and I knew you would probably ask me something like that. It’s a real sore spot for me, because of course I thought about that, on almost a daily basis in fact. I wasn’t directly involved with administering drug tests but I was in charge of the procedure, you’re right. But the bulk of the lab work we did was medical analysis for hospitals and clinics and the drug testing came later after I’d worked there for almost 2 years. Just on principle I would have liked to have quit immediately, but I had a family to consider so it was complicated. I continued working there for another 18 months or so, and it’s a huge relief to me now to finally be working at another lab that doesn’t perform drug testing. So, when you asked me to share some tips in passing a drug test for your readers, I guess I saw it as an opportunity to kind of balance my karma a little.

DEE: Thanks for your honest answer, John, and I’m really glad for your sake that you don’t work there anymore! But that brings me to my next obvious question – as a lab supervisor, I would’ve thought you’d know everything there is to know about this subject. So when you needed to pass a urine drug test for your position at the lab where you’re working now, why did you need to get my e-book on how to pass a drug test? I’ve been curious to know the answer to this ever since you told me about what you do for a living.

JOHN: Good question. Well it’s like this: part of my former job as lab supervisor was to keep up on the literature about current drug testing procedures, and to monitor information about known methods that people use in their attempts to get a false negative on a urine test. So yes, I knew I had all the information I needed to pass a drug test. But to be perfectly honest, I was also just as nervous as anyone else is who is facing a drug test. If for some reason I didn’t pass, it would have seriously damaged my reputation in the industry. So I suppose just as a way to reassure myself that I hadn’t missed anything I was looking on the Internet when I came across your e-book. It intrigued me because it was obvious to me that you had a grasp of the mechanics of hiding dilution, and I suppose I was curious about what you recommended to people.

DEE: So does that mean you agree with the entire premise of my e-book, that dilution is the best way to pass a urine drug test for marijuana?

JOHN: Oh yes, most definitely. It isn’t just the best way, it’s actually the only way. You have pretty good researching skills, and you got that part exactly right.

DEE: Thank you! But there are a lot of tips in passing a drug test out there that don’t even mention dilution, so could you explain, in layman’s terms, why it works so well for passing a urine test?

JOHN: Sure. Well, as I believe you state in your book THC is fat soluble and its metabolites are mainly excreted through the urine. THC metabolites will eventually be eliminated from fat cells over time of course, but since it isn’t possible to eliminate the fat cells themselves quickly, what a person can do is to dilute their urine output so that it has a much lower concentration of these metabolites.

Think of it like this: The human body can only contain so much water, and no more. If a person continues to drink fluids past the point at which the body is well hydrated, then the kidneys attempt to regulate the hydration level. To do that, they begin to pull water from other areas of the body in order to eliminate fluids via urination, to balance the excess fluids being taken in. Without this regulation process, along with frequent urination, water poisoning would occur (which can be fatal). So when a person drinks a large volume of water to pass a drug test, they are not actually increasing the efficiency of the kidneys. What they’re doing is simply increasing the amount of water in their urine, and thus decreasing the concentration of THC metabolites present.

I think it’s important for someone to understand this distinction. With dilution, THC metabolites aren’t actually eliminated from the body (only time or extremely rapid weight loss could accomplish that) but they are simply less concentrated in the urine. But as you know, the dilution process lowers the concentration of every other element that’s normally present in urine, which is how a test lab can identify when someone is actively trying to pass a drug test.

Tips on passing a drug test are everywhere on the Internet – so how come so many people still manage to fail their drug tests? I think it’s partly information overload, from all the companies trying to sell so-called ‘detox’ products. They have to scare people into buying their products, so they put out a lot of bogus tips on passing a drug test to do it.

Just go hang out on any pot forum. You’ll find plenty of posts made by people who used a commercial detox drink to pass a urine drug test, and failed. Sure, some do pass, but the point is they’re not reliable. Unless you have some idea of how they work, and what testing labs are looking for, you just never know for sure if you’re going to be one of the lucky ones.

But if you do have a clue about how drug tests work, then your chances of passing with a detox drink go way up. Have you ever read the instructions that come with one of them? Every single one tells you to drink tons of water along with it. So here’s one of the most important tips on passing a drug test you should know about: among all the ways to pass a drug test you can read about, just plain old dilution is the only one that works the best for a urine test. And believe me, the detox drink makers know this.

So if they know dilution is the only way to pass a drug test, you might be wondering what exactly it is that they’re selling. AH, good question. Well they know, just as you probably already do too, that dilution by itself is a big red flag to testing labs (and is often an automatic fail). So you’ve got to put a few things BACK into your urine to get around this, so the labs can’t tell you’ve been diluting.

This is where the detox companies try to fool you into thinking they’ve got some super secret formula that makes them the authority on how to pass a drug test. But the fact is, they use the same exact ingredients that are used in the much cheaper ‘home remedies’ that they try to scare you away from using. Just remember that the next time you’re reading their tips on passing a drug test. It’s all just smoke and mirrors, and one big marketing tactic.

It’s not that marijuana detox drinks never work, because sometimes they do. My complaint with them is that in the interests of getting you to hand over big wads of cash, they withhold valuable information that would make their products a lot more effective for you, the person whose life will actually be affected if you fail your test.

But even if detox drinks were a lot more reliable, one of my first tips on passing a drug test would be NOT to buy one. Not when you can make a better detox drink for a fraction of the cost.
