It was revealed in the UK press last week that in an attempt to reduce the dangers posed to their students by drugs, cheap drug testing kits have gone on sale in the student union of Newcastle university. The test kits costing around £3 are designed to identify what the substance being tested is.
The test kits work by a chemical reaction occurring between the test and the substance, that then produces a colour change. The user can then look on the colour chart to see what substances the drug contains. The idea behind the test is that the user can then make an informed choice based on the results as to whether to take the drug or not.
Drawbacks to the test kits are that often these street drugs are often cut with other substances that may not all be detected by the test, and it is often these other substances that can pose a significant danger to the user.
