One hit of marijuana will stay in a person’s system for between 3 to 30 days, if they have been clean for at least a month. The specific length of time depends on a number of different factors.
- THC is the active component in marijuana (cannabis) and this (along with the metabolites it produces when processed by your body) is what medical professionals test for.
The EMIT is used for screening, which is due to it being easy to use, inexpensive and reliable.
In order to prevent wrong positives, a "cut-off" is set.
The cut-off is - simply put - the amount of THC your urine may contain before it is considered illegal.
In most cases, the cut-off is set at 50ng/ml (50 nanograms per mililiter), which means that you do not need to "clean" your system in order to pass a drug test, but only reduce the amount of THC and THC metabolites to below 50ng/ml.
The easiest way to do this is to increase your metabolism, either through training
(up to 2000% increase) or by eating high-calorie foods which can raise it by 10%.
The halving time of TetraHydraCannabinol (THC) ranges between 0.8 to 9.8 days, so no-one will ever be able to tell you how low it will need to be for you to be (or be considered) clean. The possible variations are simply too great - for an infrequent user with good metabolism, it can be three days, but for a steady/frequent user with bad metabolism and a lot of body fat, it might be up to 45 days.
The main factors are:
- Metabolism: A high metabolism means the THC will be cleaned out quicker.
- Fluid Intake: Again, a high fluid intake will help clean out the THC.
- Tolerance: There are many examples of frequent users whose tolerance makes them able to quickly clean the THC from their system.
- Frequency of intake: The less, the faster.
- Amount of Cannabis: The less, the faster.
- Potency of Cannabis: The less, the faster.
- Amount of body fat: THC stores in the body's fat cells and is then released slowly, so the less fat, the quicker the cleaning process.
- Train regularly.
- Drink lots of water.
- Eat plenty, and eat high-calorie foods.
However, the drug has been ruled as legal for medicinal purposes in a number of places. These include Canada, Belgium, Holland, Israel, the Czech Republic and various states within the USA.
Effects may be felt from a single hit of Marijuana (or the substance still present) between 3 to 30 days after use. The average is about 3 days, and generally no more than 10 days for an occasional user.
There is a chemical within the drug called THC, and the amount of this will determine how strong the hit will be, as well as the length of time that it will last. Various factors such as age, weight, and how the drug is taken (whether orally or through smoking) will decrease or increase the period during which it will stay within the body.
A person with a higher body weight will store more of the THC than a thinner individual, because THC is absorbed by fat. If the person also has a low metabolism, then this will increase the length of time the THC stays within their system.
Remember that marijuana is illegal in many countries, so professional legal advice should always be sought before getting involved with it in any way. Never feel pressured by others into using it either.
