While majority of our customers need help in making a drug test come up negative, it is quite unusual to hear a question about how to make a test positive. But it happens.

- Hi there! I need to pass a drug test, but I need something to show up on it, and I need something not to show. How do I do that?
- What toxins are we talking about?
- I’m a casual smoker, but I also take some prescription medication, and I need that to show.
- Ok, when is your test? If you stop smoking but keep on taking your medication, it will show on your test. You can a cleansing kit to help your body get rid of THC faster.
- Yeah, the thing is though; I don’t want to stop smoking. Last time I had a urine test, and I used this drink to make my urine clean, but I took a little bit of a tablet, crushed it and put it in the cup, so I tested positive for meds, but I passed for pot. Now I have a saliva test, I don’t know why they switched it, but I was wondering – can I do the same thing? Do I just suck on a pill before the test?
- Let me ask you something before I explain. How long did you abstain from marijuana before you used a drink for your urine test?
- I don’t know, I think I stayed off it for a week or so. But I’ve been taking the detox pills every day; I have to take them every day!
- Ok, here’s what happened. When you stopped smoking marijuana, you decreased your toxin level and detox drink hid the remains of the toxins in your urine; since you were still taking prescription medication, the level of those was high enough for the drink not to cover it, that’s why you tested positive for it. Adding medication to your urine will not make you test positive – they check for metabolites of the drugs, not the drugs itself, so you would need to process it through you body for them to detect it.
- Oh, I see… So I just do the same thing here? If I get that detoxifying mouthwash but keep on taking meds, it won’t cover it, right?
- Yes, you got it! Just make sure to stay clean of THC for at least 48-72 hours.
- Yeah, that’s no problem, my test is not for another couple days and I already stopped. Thanks a lot!

Drug tests are set up in a way to see what person have been taking, so it is sensitive to drug metabolites – the by-products that are left in your body after ingesting them. Adding something to the sample in order to test positive simply will not work.
