How effective is Urine luck Additive if the sample is sent to a lab and not tested immediately?
The use of drop-in additives is not recommended. They will not work if its an instant-type test because it takes approximately 90 min to fully destroy the drug metabolites in a urine sample. Plus, labs are detecting the use of additives and had been for quite some time. They are detected when the sample gets flagged for excessive nitrites, high chromates, and/or an abnormal pH.

If youre going to sneak something into the facility, you might as well make it count and sneak in something that will work - a clean urine sample for a sub.
