Spikey™ tests for minimal standard dosages of Ketamine, Cocaine, Scopolamine, and GHB (gammahydroxybutyrate) in drinks. Smaller quantities may not be detected. Follow instructions exactly. Do not place the test in a drink. Some substances, such as those that are dark red in color or milk-based, may produce a false positive. Bitter lemon and lime cordial will produce a false negative. A drink producing a negative result could still be unsafe as it may contain dangerous substances other than those tested for. If in doubt, do not consume your drink. Store away from children, animals, chemicals, and moisture. The manufacturer makes no representations or warranties, except as expressly stated above, and cannot be held responsible if you leave your drink unattended or for the presence of any substances not detected by this test strip, and excludes all liability for consequential and other losses to the extent permitted by law. The manufacturer’s liability for a defective product is limited to a replacement or refund of the purchase price.
