How the drug detector works
THE test kit used to find traces of heroin in RTE can pinpoint four drugs using special equipment.
- Cannabis, heroin, methamphetamines and amphetamines can all be detected using 'Detect 4 Drugs'.
- Surfaces are wiped with a piece of specially designed paper.
- The paper is then sprayed with a chemical.
- Traces of different drugs then appear as different colours on paper. For example, heroin appears as purple.
