DOT Drug Test Guide: How Long Will Drugs Stay In Your System?

It is crucial to start this particular article by saying that the detection window for drugs depends on numerous internal and external factors.

For instance, it is different if you consumed weed first time in your life compared with chronic consumers, and the same thing works for other drugs as well.

Prescription drugs are also problematic primarily if you operate heavy machinery or drive truck long distances. The best way to learn about workplace drug screenings is by clicking here for more info.

In both cases, prescription pills can affect your ability to operate machinery properly; they may cause drowsiness and reduced reactions, which may endanger other employees and traffic participants.

That is the main reason why we decided to present your windows of detection so that you can cleanse yourself beforehand.

Let us start from the beginning.

1.    Cocaine

In case you casually consume cocaine, you will be able to cleanse it in a matter of days. Keep in mind that it tends to linger within your system up to four days for short-term users. On the other hand, addiction can lead to severe intoxication, which will affect the detection window as well.

You will be able to experience a high up to an hour, which is a half-life of this particular drug. It means that half amount you consumed already left your body.

However, if you are using it frequently, it will accumulate within the body tissue, which means that you will need more time to cleanse it from your system.

When it comes to urinalysis, the things are entirely different, because a test can display the presence of drugs up to 21 days depending on the amount. The effectiveness of urinalysis depends on the dosage and purity of the cocaine you consumed.

For blood tests, you can rest assured because it is sufficient for detecting the presence up to two days after consumption.

Finally, you should know that it will remain in sweat glands for several weeks, which means that the hair follicle test will show the presence even when you stopped using it.

2.    Methamphetamine

You can find vast array forms of meth, including speed, crystal, crank, or just meth. Remember that in all cases, this particular drug will affect your central nervous system and release dopamine as the reward neurotransmitter.

It will also affect serotonin and norepinephrine, which will provide you a similar effect as cocaine, but you will need more time to cleanse your system. Generally, methamphetamine metabolites of byproducts will remain in your body at least twelve hours after consumption.

It is detectable a few hours after you use it, and you will need at least five days to cleanse your urine from it. Remember that DOT drug test such as urinalysis is highly accurate when it comes to detecting meth usage, but only in a short period, as we have mentioned above.

Keep in mind that methamphetamine metabolites will stay in your blood and saliva for up to three days, depending on consumption. At the same time, blood screening is the best solution for detecting the current intoxication because it will enter the blood in a matter of minutes.

The main problem lies in hair follicles because a single sample can show up to three months of consumption. Its half-life is twelve hours after consumption, which means that half of the amount you consumed will get out of your system.

Generally, you will need up to two weeks to thoroughly cleanse your body from it, but it depends on your constitution, metabolic rate, and the amount you consumed in the first place.

3.    LSD

This particular drug comes with a short half-life compared with other ones that we have mentioned above. Its half-life is approximately three hours after consumption, while the effects will last up to eight hours.

The main problem is that LSD will linger in your system longer than you expect. It will break down into metabolites within your body and get inside the urine, which means that urinalysis can detect it for up to five days from consumption.

The hair drug test is entirely different because it can detect long-term abuse, and the perfect frame can reach up to ninety days from consumption, which is an entirely different approach.

However, urinalysis for the detection of this particular drug is not sufficient; because of the minimal amounts, you will have it. Generally, your body will metabolize it quickly in a matter of a few days.

That is the main reason why other tests such as saliva, blood, or hair are more useful for detecting this particular type of drug.

4.    Amphetamines

You should know that similarly, meth and amphetamines come in different forms as well. At the same time, a single dose can last up to four hours, depending on your tolerance and other factors.

Half of it will leave your system in a matter of 24 hours. However, urinalysis can detect its presence up to two days after consumption. If you are a chronic user, it will stay in your system for a week tops.

It will remain in your saliva and blood for up to 12 hours, which means that these tests can detect whether you are currently intoxicated or not.

Finally, a hair analysis will detect everything you consumed in the last three months, which is why it is the most expensive solution.

However, it cannot detect things you consumed yesterday or the day before, because metabolites will reach the hair sample in seven days after consumption.

5.    Marijuana

Weed tends to stay in our system for a short while as an active substance such as THC. However, when our bodies break down THC into THC-COOH, this particular byproduct can linger in our bodies for a long time.

If you are a chronic user, you will need more than a month of abstinence to cleanse yourself thoroughly. Since THC is fat-soluble, it will merge with fatty cells you have, which means that the more fat percentage you have, the longer you need to cleanse yourself.

On the other hand, if you use it occasionally, it will remain in your urine for a week, while it can remain in hair up to three months, similar to other drugs we have talked about.
