Prepping for a marijuana drug test can give anyone the chills, more so when the drug test results are standing between you and a promising opportunity.
For skinny people, there’s an interesting twist to this; will being skinny help you flush out weed from your system faster than your chubbier counterparts? This is what I want to discuss with you in the next two minutes, so stay put.
How is weed expelled from the system
In brief, weed is eliminated through five primary channels: urine, sweat, saliva, feces and exhalation.
The psychoactive compound in weed that is screened for during drug tests is called delta-9- tetrahydrocannabinol (THC).
When you smoke weed, THC will hit your blood stream almost instantly. However, when you take weed edibles, the weed will pass through the digestive tract before it can get to your blood stream. In the liver, THC is broken down into active metabolites; THC-COOH is the most common THC metabolite.
Drug tests screen for both THC and THC-COOH. How long THC lasts in the body is related to the half life of THC. Half life is the amount of time it takes for 50% of the drug to be eliminated from the body. The half life of THC is 28h-32h, this means that it should take roughly five days to a week for THC to be eliminated from the body. However, this will also depend on a number of individual factors which include: Body fat percentage, exercise level, age, frequency of use and for how long one has taken weed.
Body Fat And How It Affects Elimination Of THC
Both THC and THC-COOH are highly lipophillic, meaning that they bind more readily to fats than to water. It is estimated that the amount of THC in fat is about 100 times more than it is in blood. This means that only a very small fraction of THC is present in blood at any given time. However, the THC is free to move from the blood to fat cells and vice versa.
Thin People Versus Fat People
Being skinny or fat in this context refers to body fat percentage and not body weight per se. Let’s take the example of three people with different body fat percentages: 10%, 20% and 30%. They all take the same amount of weed using the same ingestion method. What happens to the THC concentration in their blood and fat cells after some time?
The THC will peak after a few minutes and then reduce and remain at a certain low threshold afterwards. This applies to all the three subjects.
The subject with 10% body fat has less fat cells to hold the THC. This means that their fat cells will get saturated much faster as compared to the subject with 30% body fat. This extra fat stored in the subject will prolong the half life of THC so that it will take a longer time for this subject to eliminate THC from their system. The difference primarily arises due to the amount of fat captured in fat cells.
The same applies to THC metabolites, most of which are also highly lipophillic.
How long for a skinny person to pass a drug test
With the above background, it is safe to say that a skinnier person will eliminate THC from their body faster than their heavier counterparts. This means that they may be more confident about passing a drug test sooner after consuming weed.
THC is eliminated from the body after about 5-7 days. However, other factors are compounding and make this claim a little bit ambiguous. How long THC stays in the body is affected by a myriad of factors and it is impossible to claim that a skinny person will definitely eliminate weed faster. You must take all factors into consideration before deciding who will test negative for weed sooner than the other. These factors include: age, frequency of use, duration of use, and cardio activity level.
