It really depends on the brand of testing, and who/where it is being tested.
Some are so sophisticated that it is virtually impossible to trick them into anything.
However, the most effective way is actually the simplest: Flushing.
This is when you drink lots of water before your test, to produce urine that is so diluted that drug traces are too small to be flagged up.
There are 2 drawbacks to this method:
- Some tests treat overly diluted urine as suspicious because this method is well known.
- Drinking too much water can kill you through water intoxication, so be careful!!
More ways to pass an ETG test
Ok, so you asked for 3 ways - but flushing is the only one that REALLY works, so I guess that leaves me with two other bits of advice:
1. Don't drink before the test. Sounds obvious, but you'd be surprised how many people fail because they can't help themselves.
2. Buy yourself more time. Come up with a scenario for why you might come up with a "false positive".
One of my favorites is saying that you visit a sick relative in hospital often and are exposed to the sanitizer Purell. This substance has been known to trigger false positives in ETG tests, so asking your examiner whether that may have some effect (be sure to tell them you visit A LOT), and this may get you off the hook for at least some time depending on the circumstances of the test.
