Chart: Seizures of the most harmful drugs at UK borders are falling

Border Force is responsible for seizing drugs at ports, airports and international parcels depots. However, reports by the Chief Inspector of Borders and Immigration suggest drug-detection efforts are hindered by understaffing, lack of training and focus on conducting passport checks on travellers. Most drug seizures are of small amounts: only 19% of seizures involve more than one kilogram of drugs.

I am a lecturer in crime science at the Jill Dando Institute of Security and Crime Science at University College London (UCL). I am interested in crime analysis – particularly how crime concentrates in time and space – in crime prevention and in transport crime.
