 Data on secondary drug use are only collected among all treatment clients and not separately for new treatment clients. 

 ‘Opioids’ include: heroin, methadone, other opioids; ‘Cocaine’ includes: cocaine HCl, crack cocaine; ‘Stimulants’ include: amphetamines, MDMA and derivates, other stimulants: ‘Cannabis’ can include herb or resin. For each client up to four secondary drugs can be reported. 

 A number of the clients report using the same drug both as primary and secondary drug, particularly for cannabis. Clients may report using different sub-types of the same substance, as defined in the TDI protocol for the drugs categories. The greater part of clients using cannabis both as primary and secondary drug comes from Germany.
