A drug test is usually part of a job screening process, especially for a position in government. It is rather common, but a process that seems to be shrouded in half-truths and myths. Depending on the drug, drugs can be detected in the urine seven days post exposure, 90 days in head hair, and more than 90 days in body hair. But most employment agencies will prefer head hair, as it’s easily obtained and sanitary compared to the other two sources. It is a preferred method to test for drugs as it’s almost impossible to cheat.
Myths Surrounding Follicle Drug Tests
Does a secondhand smoking cause a positive? No. There was a test where a recipient was placed in an isolated room with THC smoke. Lab tests were only able to detect about 3 mg of the active narcotic in the hair. Most tests designed to detect drugs in the hair follicle are set at 50mg/ml.
Detoxifying shampoos do not work. This is false — the right shampoo can help you pass a hair drug test.
Learn How To Pass A Hair Follicle Drug Test
You have the option of shaving all of your hair. It takes about a week for any exposure to drugs to show up in a drug test. That means you have the opportunity to shave off your body hair and have about a week’s worth of drug-free hair that won’t be detected by most drug tests. However, many people forgo this method, especially women. It’s a rather dramatic approach that most don’t feel comfortable committing to.
If you decide to cut your hair to deter a follicle drug test, it is important that you do it right. For example, if you expose your body to THC on a Sunday night and shave off your hair on Monday, you will have a slight amount of hair by Friday. That new hair that has grown in the past couple of days will probably not have traces of drugs. However, once it becomes Sunday of the following week or later, then the drug particles will be detected by most tests. Shaving your head hair to deter a test tend to be a viable solution for light users or those who smoke once every two weeks or so. Labs and drug testing facilities are only designed to find patterns of heavy, regular usage.
Certain shampoos can also help you pass a drug test. One of the more popular shampoos that have a following due to its ability to help with follicle tests is the Nexxus Aloe Rid Shampoo. This shampoo is marketed as a clarifying shampoo, removing trace components of sebum, dirt, and grime — and allegedly it can help even strip traces of drug usage in the follicle.
When you consume drugs that contain THC — like marijuana — the liver will break down the active ingredient into a metabolite called THC-COOH. This is the component that laboratories and drug testing facilities look for. Hair is made up of several layers, including the cuticle, cortex, and medulla. The metabolite stemming from the THC exposure is usually stored in the cortex, and protected by several layers of the hair’s cuticle. These overlapping cells are hard and can be about 12 layers thick. For the THC-COOH to be eradicated from the hair, you need to penetrate the hair’s shaft. This is where clarifying shampoos can be useful, as their astringent and detergent properties are augmented when compared to regular shampoos. The Nexxus Aloe Rid Shampoo uses a mixture of blended ingredients including propylene glycol. The addition of the glycol has a softening effect on the hair, allowing the cuticle to open and be exposed to the detergent in the shampoo, gently removing impurities like THC-COOH. For the best results, the shampoo should be used on a daily basis for at least ten days straight to be effective.
Now that you are equipped with the fact that traces of drugs can be detected 90 days post-exposure, you can gently detox yourself from the drug if you know that you will be joining a job that does regular screenings. If you are interested in a prospective job, you can anonymously inquire about drug testing, or acquaint yourself with a former or current employee.
Also, take note that everybody’s body chemistry is different — one method that works for one person to deter a drug test may not work for you and vice versa.
