The Macujo Method

This takes longer to prepare but is quite simple and easy. I am going to make it as simple as possible to understand. Make sure you follow every step in the same order. This will ensure you don’t end up forgetting a single step.


  1.   Avoid drug use as it will make the detox process harder.
  2.   Gather ingredients and thoroughly rinse your hair with water.
  3.   Next, take vinegar and massage the scalp.
  4.   Take Clean and Clear wash. Apply to hair and leave for half an hour with a shower cap.
  5.   Wash hair thoroughly and then use any detox shampoo twice.
  6.   After the shampoo, apply the mentioned detergent and wash your hair.
  7.   As the final wash, use Zydot Ultra.

Wearing fake hair

Wigs are easily traceable. You can notice them even from a mile away. They usually don’t fit properly, don’t combine well with your natural hair color, or slip often. Also, synthetic hair can be tracked apart from human hair.

Going bald

Indeed, you cannot grab hair samples from a recently shaved head. However, shaving a day before the drug test does seem fishy. In such cases, the drug tests are usually done using body hair. Besides, body hair takes longer to grow which can reveal longer periods of drug use.


You can try to pass drug tests by bleaching your hair. But it would be a total failure. Studies reveal that one bleach can remove 40%-80% of metabolites. However, it doesn’t remove 100% of the drug residue. While the bleach method may work for some, it may not work for all.

Variables That Decide How Long Marijuana Stays in Your System

How long does delta 8 stay in your system? No one knows this for definite. But many factors determine how long the drug stays in your body.

How Often It Is Used

An individual who frequently uses marijuana will have a huge buildup of the drug in the body. This means that the drug will take longer to leave the body.

The Type of Marijuana

Different types of marijuana have different levels of THC. So, if you use marijuana with a high level of THC, it will stay longer in your body.

How it is Used

The method of ingesting marijuana does impact how long you can detect it. If you smoke the drug, the THC levels will drop after a few days. But, if you ingest it, the body takes longer to break it down. Thus, it stays detectable in the body for a longer period.

Body Mass

As we discussed earlier, THC is fat-soluble which means it is stored in the fatty tissues of the body. So, an individual with less fat in the body will clear THC faster than those with more fat. In simpler words, a person with good activity, eating well, and sleeping well will eliminate THC faster. On the other hand, a person with poor health will take longer to eliminate the traces of THC. But, doing too much exercise before a drug test can spike the THC levels. This happens because THC is stored in fat tissues. When you exercise, the fat breaks down and the THC is released in the body making it easily traceable. Every individual has a unique metabolism rate. Thus, this changes the way everybody breaks down THC.

Interfering Drugs

Some drugs can impact your body and prolong the THC detox process. This happens because they interfere with the THC levels in your body. Here are some drugs that can spike the THC levels in the body.

  •     Erythromycin
  •     Ketoconazole
  •     Verapamil
  •     Clarithromycin
  •     Boceprevir
  •     Itraconazole
  •     Voriconazole
  •     Clarithromycin

Final Thoughts

There are many drug users or marijuana users that look for a quick fix to clear the hair follicle drug test. But, with hair follicle drug tests, there isn’t much you can do. You could try the popular methods that we have listed above. Try detoxifying shampoo like the Toxin Rid Shampoo or the Majuco method. Because of them, the drug residues don’t get detected. 

Fortunately, these hair follicle drug tests aren’t 100% true. There have been cases where individuals have tested positive because they were in contact with a marijuana user. In addition, if you have been in contact even with the marijuana plant, you could test positive. But, as an employee, if you test positive, you will have a tough time proving yourself.

Without wasting time thinking about how long weed stays in your system, it’s practical to keep a distance from drug use. So, if you want to pass the hair follicle drug tests, it is best to avoid the consumption of these harmful drugs.
