Drugs and packaging (clingfilm, polythene bags, etc.) Cases involving drugs generally relate to seizure of bulk quantities of drugs. We regularly comment on: • amounts for personal use; • tablet manufacture; • results of chemical profiling of heroin; • cannabis cultivation, including hydroponic set-ups and yield calculations. We also provide expertise in the examination of packaging (e.g. clingfilm, poly bags) and review work undertaken by the Crown. Items such as clingfilm and poly bags can contain features and marks that are not visible to the naked eye. These marks and features can be examined on items used to wrap drugs and compared to, for example, a roll of bags or a roll of clingfilm recovered in relation to a case. We cannot, unfortunately, provide comment on the monetary (‘street’) value of drugs.
Hair analysis We also provide drugs screening and analysis with regard to hair samples. As one centimetre of hair contains on average one months information it is obviously a more effective test which covers a longer retrospective time frame than blood/urine testing.
