What is the best urine drug detoxification?

There is no best, they are all useless and do nothing but mask what is in your urine. If the sample is sent to a lab then they will find it regarless of what your try to use to flush it out. Vinegar or cranberry juice do nothing, and i have even heard of using bleach...which will not only not do anything for your urine sample, but it would probably kill you or send you to the hospital at the very least. If it is a dipstrip test, your best bet is to dilute your urine by drinking large amounts of water to the poin that your piss is as clear as water. If the sample is going to a lab, then you are screwed. The best urine detoxification for a drug test is abstinence.


Can you use 3 day old urine for a lab test?

No . The urine should be tested immediately with a home test or the sample provided at the doctor's office or clinic. Sometimes you will be asked to bring a sample to the lab of the 1st urine you pass in the morning. But it should be that same day, not stored for 3 days.

Do you need a prescription for lab tests?

No. Your doctor will write a request form for the lab to test your sample (blood, urine, faces, swab etc). Depending on the test you may need to collect the sample yourself e.g. urine or stool sample. If it is a blood test, you will need to go to phlebotomy at your local hospital to have a sample of blood collected. However, some nurses at your local surgery may do this. For biopsies of skin or complex procedures you may need to attend a specialised clinic to have the sample collected. A prescription is only for medication. Not for a laboratory test.

Can Charcoal tablets get rid of THC?

No, scientifically charcoal will not "get rid of THC" which is actually very hard to do. Charcoal cannot flush or mask marijuana in a urine test. Most schemes to pass a marijuana test will either dilute the urine or mask it with chemicals so the sample passes a quick stick test. This does not do much good if they send the sample to a lab for further processing.
