All these are not funny circumstances and can have quite serious problems in life.
Now, there is a host of usual methods that you could try. You would need to quit smoking for the time being first, and drink water aplenty. Flush out the THC residues constantly, and stop being nervous! What is going to happen is good only, all you must do is to keep trust in Marley and the resources the internet provides for such odd jobs.
Obviously, there are other natural options like using a few drops of vinegar in warm water or drinking up a diluted solution of baking soda. These would also work to some level but to be fully sure, you would need something professional.
Other usual methods
Nevertheless, it is good to have a fair idea about all the detox choices. The knowledge helps you to decide if they are right for you and what can you expect from an official kit. Apart from the water, baking soda and vinegar remedies mentioned above, you can also check out other highly gross methods like sneaking in an alternate urine sample from a non-addict pal or willing family member. In this context, it is super relevant to know that nowadays you can buy THC free pure urine samples over the internet as well. See if this strategy suits you. Many may prefer to keep this as a backup plan if nothing works.
The level of residual trace in your sample would depend on a lot of factors, such as your pattern of smoking, method of using, height, weight, and body fat among other things. Other alternatives to work with the pee include adding a few drops of bleaching powder or eye serum carefully to the sample. However, please remember that if your sample is too clean, it can still be a suspicious proposition and you may have to appear for the test again.
A verified solution
A good service should be always clarifying the relative effectiveness of their product. It should also clearly explain why other options may not be sufficient to prove your sample’s drug-free state. Check out whether you can receive the kit as fast as you can. Look up the components. See if they make it with natural elements. Also confirm if they have an integrated testing strip in the kit so that you can be sure before going for the actual official test.
