Drug testing for legal highs has been limited by the ability of drug test manufacturers to copy the subtle changes to drug chemistry and changing fashions. Almost as soon as one designer drug becomes established with users, the law is adjusted to make it illegal and the design is altered slightly in chemical terms to a slightly different drug compound which avoids the legislation.
Designing specific tests for this ever changing chemistry is understandably problematic. It is not possible to make drug tests which cover this diverse chemical variance without making the tests unspecific and unreliable. To develop a test, manufacturers need to know the market for test kits will be sufficient and sustained to cover the costs of development and certification.
In light of the above, it is not surprising that there is only a small range of drug test kits currently available for legal highs and designer drugs.
These now include:
You will note none of the above remain “legal highs” in UK law
