About IDEA

Who are we?

The Independent Drug Expert Alliance has been established as an inclusive, impartial, and truly independent network of drug experts.

 

We are committed to fairness, transparency, and objectivity across the drug expert community and within the criminal courts of the United Kingdom. Accordingly, the Alliance does not exclude any individual who contributes to this field.

 

Originally founded by retired police officers, who continue to work as practising drug experts and trainers, alongside one of the UK’s most respected and experienced forensic scientists, the Alliance recognises that unnecessary secrecy and information hoarding persist among Criminal Justice System drug experts on all sides. We believe that greater openness is essential.

 

By sharing credible, reliable, and critical information, we aim to collectively reduce both the time and costs associated with UK criminal drug trials, while enhancing the knowledge and capability of all drug expert witnesses.

 

Our mission is to support any member working as a Drug Expert Witness, or within a related area of expertise, across the Criminal Justice System.

Our Aims & Intentions.

At our core is the open and impartial sharing of knowledge in a complex field with the aim of expanding the expertise of all drug expert witnesses.

  • To be Inclusive as an Alliance

  • To remain Impartial as Individuals

  • To support each other as Independent Drug Expert Witnesses
