Trick:
Over hydrating in an effort to dilute their urine.

Prevention:
Ask people not to drink fluids in the hour leading up to the test. Testing kits are able to detect if the sample is too diluted to provide an accurate result. If this happens, wait 2-3 hours for it to concentrate to an acceptable level.

Trick:
Chewing gum to dilute saliva.

Prevention:
Salivary test candidates should not be drinking, chewing, eating or smoking at least 20 minutes before a test. If they have, you will need to wait to ensure an accurate test is returned.

Trick:
Detox products such as instant clean, ultra clean and SOS mouthwash.

Prevention:
Detox products generally don’t work, but the best way to prevent them is by undertaking random, post-incident, blanket and/or suspicion testing programs where people don’t have the opportunity to tamper with their sample.

Trick:
Substitute or synthetic urine.

Prevention:
Urine based testing kits will identify if the temperature of urine is correct.

Trick:
Placing bleach, ammonia or Drano in the urine.

Prevention:
This can be picked up by the testing kits. The Screener should be able to smell these substances from a distance.

Trick:
Prosthetic penis including heat pads to warm sample.

Prevention:
The Screener will need to listen for the plastic lip unbuckling on the kit. The user will often try to mask this by wearing a belt or blocking out the noise with a cough or something similar. Close supervision is essential. Any movements can be a giveaway but the trained eye of an experienced Screener is hard to fool.
