You've just landed your dream job. Congratulations! Now you just have to pass a background and drug test and.... oops. Perhaps you hadn't anticipated actually getting the job, or maybe you use it medicinally. Whatever the reason be, you suddenly find yourself scurrying the internet hoping to find out when the pot will be out of your system. So....when will the pot be out of your system...?!
Although conventional wisdom says at least 30 days, the answer is not very straightforward. There are many different kinds of drug tests available, which have varying levels of sensitivity and time periods to detect cannabis in your system.
The total amount of time that weed stays in your system depends on the conditions of the user and how frequently they smoke marijuana. As you smoke cannabis, the THC accumulates in your body. The more cannabis you find yourself consuming, the longer it will take for that THC to clear out of your system. The term is called saturation. How quickly you metabolize THC as an individual will also affect how long the chemical stays in your system. There are several important variables that factor in here too, such as what method of test is being administered. Given these variables, here is information for you to help gauge how long cannabis stays in your system.
So, ...how long does cannabis stay in your system?
Each of us has a unique metabolism that processes cannabis at a different rate, further complicating the picture. Even amongst people of the same gender and age, individual lifestyle choices such as levels of exercise and eating habits may also affect the amount of time required to pass a drug test (those with higher levels of fat content store cannabinoids more readily than leaner folks).
The most common way to test for THC, the primary psychoactive ingredient found in cannabis, is via simple urine testing. Urine testing is both the cheapest method and it has a long detection period. Urine and other tests like it do not test for THC itself specifically, but rather for a THC metabolite called THC-COOH. The presence of this metabolite means that the body has recently processed the chemical.
How long does it stay in your urine?
The length of time will vary depending on how often you consume the green herb. When it comes to how long weed stays in your system. THC is stored in the body's fat and therefore accumulates in the body gradually over time. It essentially doesn't matter how you consume cannabis, the more you smoke, vape, or eat the herb, the longer it will be detectable in your urine. Here's what you should know before you find yourself peeing into one of those little cups.
In general, here's how long cannabis can be found in your system:
For single use: up to 8 days
For frequent use: up to 15 days
For regular use: up to 30 days
For heavy use: 45-77 days
As a general guide, if you're a regular consumer of marijuana, the chances are THC will remain in your urine for even up to a month after stopping. That's why it's good to stay frosty, on your toes, since this is also the most likely and frequent way you'll be tested for weed in your system.
How long does it stay in your hair?
As far as the question how long does weed stay in your system, hair can often be a chief concern. There is a lot of debate on whether or not hair testing is accurate since cannabis is thought to have the most extended detection window in hair. All standard hair tests look for the presence of drugs over the last 90 days.
Since hair grows at a fairly standard, consistent rate, laboratory technicians will test a short hair sample taken extremely close to the scalp. This sample will provide a record of your overall health and even what you've consumed over the past three months. What the technicians will ultimately look for depends on what was ordered in the test, so if you aren't being scanned for drugs use don't get anxious.
Cannabis metabolites will show up in hair after about seven days post-consumption of pot, but hair testing for cannabis is not very common.
Clear Choice Hair Follicle Shampoo is easy to use and is a highly effective detox shampoo, that coats the hair follicles so the toxins are not detectable in many tests.
How long does it stay in your blood?
Some officers opposing recreational cannabis use are attempting to prevent driving under the influence of cannabis with roadside blood testing. That might make you concerned about the question at hand; “long does weed stay in your system?”. However, blood testing for cannabis is not extremely common. THC and THC metabolites do not stay in the blood for very long. Instead, the cannabinoid likes to find itself a nice, fatty spot to land. Getting an impromptu blood test for cannabis would be fairly unusual, so take a quick second to glance over the doctor or police officer for a Dracula cape. Just in case.
In general, here’s how long you can expect to test positive for THC in the blood:
For single use: up to 24 hours
For frequent use: up to 3 days
For regular use: up to 1 week
How long do other chemicals stay in your system?
When compared to most substances, cannabis stays in your system for a very long time. If you are a frequent drug user, it’d be useful to know the distinctions between different narcotics and how long they’ll remain in your system. Better safe than sorry. In general, here’s how long different substances will show up positive in a urine test:
Amphetamines: up to 2-3 days
Alcohol: up to 5 days
Cocaine: up to 2-10 days
Phencyclidine (PCP): up to 7 days
Opiates (including heroin): up to 2-5 days
LSD: up to 2-3 days
Psilocybin: up to 5 days
Ecstasy/MDMA/Molly/Sass: up to 1-3 days
In blood and saliva tests, as far as how long does weed stay in your system, expect traces of these substances to be present for up to 24 hours. As mentioned above the standard hair test will check for a 90-day history of substance use.
Drug testing is a standard part of life for many in the working world these days. However, because of the varying detection windows for each of these substances, it is easier to get away with having a problem with amphetamines than it is to be a cannabis smoker.
So how long does weed stay in your system?
Given the technology that is available, shouldn’t there be some leniency towards the frequency of use with cannabis? It is legal in some states and countries now, after all, with more places lining up to legalize every day. Why should you continue to worry about how long does weed stay in your system.
In fact, after legalization, if drug testing is not altered, the risk to the workforce is extreme. With 13 percent (one in eight) of US residents admitting to regular cannabis consumption, demonizing cannabis consumers in the workplace could result in a giant loss for local businesses.
Cannabis stays in the system longer than almost all other chemicals in the body because it accumulates in body fat. However, everyone knows that you´re not necessarily high 12 hours after use.
