The drugs most commonly encountered in the laboratory are herbal cannabis, cannabis resin, heroin, cocaine, amphetamines, BZP and MDMA tablets.

which has led to an exponential increase in the variety of compounds submitted to the laboratory for analysis. As a result hundreds of different compounds can be analysed by staff on an annual basis.
