The National Offender Management Service (NOMS) records all incidents on the Incident Reporting System (IRS). The incident reporting system provides the option for the drug found to be recorded as any of Amphetamines, Barbiturates, Cannabis, Cannabis Plant, Cocaine, Crack, Heroin, LSD or Tranquilisers. If the drug found is not suspected to be one of these, then the drug found will be declared as Other. This will include New Psychoactive Substances, steroids and drugs of unknown type.
If substances in the Other category become easier to define NOMS will review the options for recording them more specifically
