Add some pee (to half or even much less, only to color the water a little) and add the rest water (other half or even more). Then shake it. As when amphetamine is in your body up to: 2-6 days (in urine), marijuana stays (is detectable): 14-31 days (very long).

Picture: home drug test product – it's commonly used by parents to "protect" their children from drugs. I didn't wanted to judge this method, but it's the worst thing you can do. If you're kid
is a drug user – the best and the only effective method is to him understand the consequences of his decisions on himself and until he, by himself don't approach you – "I need help" – you shouldn't do anything (only secure your valuable items in home, your credit cards).
What you can only do is to criticize him by the things he is doing, because of the usage with of the drugs (but !NOT to call a junkie or a drug addict [!]). BUT those things needs to be connected with the drug he is taking! In addition: when he smokes Marijuana be sure that you're criticise him for his none or "very bad" memory or "laziness" (for example: "oh, you
forgot again! look at you memory, you can't remember what [must be important TO HIM!]). It must be the reason which is connected to usage of the drug. If you can't identify the substance which he is using start to educate yourself (there are specific signs, "outer") for which you can easily identify almost any substance. Look in the eyes, the answer is there, but do
it: "hidden" way.
It would work, because to detect that the urine was cheated, testing person must do the "urine adulteration" test first (* second, separate).
This might be helpful (table below), those substances which aren't listed are almost very rarely to be detected (because there are no tests, in common on them).
Remember also one important thing: it's not illegal to have drugs (or drug metabolite) in your organism. Illegal is only possession of illegal drugs (substances) and only for that you could be sentenced.
In addition: when you've got tests on blood practically when you're not "on" it's weak chance to detect any drug (but it may differ from drug, like: benzodiazepine). In hospitals sure is that they don't have "urine adulteration" kit to check if the urine is "valid" (not diluted). Remember this information.
If were only a "passive smoker" (of marijuana, hash), where your friends smoked with you (and you're normally don't smoke) – there is a tiny bit of detection after 2-3 days (but for sure you didn't were in a small room with them with no ventilation).

A drug test is a technical analysis of a biological specimen - for example urine, hair, blood, sweat, or oral fluid / saliva - to determine the presence or absence of specified parent drugs or their metabolites. Major uses of drug testing are to detect the presence of performance enhancing steroids in sport or for drugs prohibited by laws, such as cannabis,
cocaine and heroin.
