Drugs of concern
In 2018–19, for clients in Queensland receiving treatment episodes for their own alcohol or drug use:
- alcohol was the most common principal drug of concern (34% of episodes) (Figure 10; Tables SE QLD.10)
- cannabis was the second most common principal drug of concern (28%). In Queensland, the level of cannabis reported as the principal drug of concern is a result of the police and illicit drug court diversion programs operating in the state (Table SE QLD.12)
- amphetamines were the third most common drug of concern (25%); where amphetamines were recorded as a principal drug of concern, the most common method of use was injecting (58%), followed by ingesting (19%) and smoking (18%)
- within the amphetamines code group, methamphetamine was reported as a principal drug of concern in just over 4 in 5 (83%) treatment episodes; in half of treatment episodes where methamphetamine was the principal drug of concern (51%) injecting was the most common method of use. This was followed by smoking (40%) (Figure 10b).
Some jurisdictions are working with service providers to encourage more specific reporting of amphetamine use (i.e. to reduce the use of ‘amphetamines not further defined’ code where possible).
Clients can nominate up to 5 additional drugs of concern, these drugs are not necessarily the subject of any treatment within the episode (see Technical notes).
When the client reported additional drugs of concern:
- nicotine and cannabis were the most common additional drugs (both 18% of episodes), followed by alcohol (16%) and amphetamines (11%) (Table SE QLD.11).
Over the period 2014–15 to 2018–19:
- Alcohol replaced cannabis as the most common principal drug of concern in 2018–19. Cannabis was previously the most common principal drug of concern, since replacing alcohol with a higher proportion of treatment episodes in 2014–15. The proportion of episodes reporting alcohol as a principal drug of concern ranged from 40% in 2015–16 to 32% in 2017–18 (Table SE QLD.10)
- amphetamines remain the third most common principal drug of concern, with treatment episodes increasing since 2014–15 (15% to 25%)
- within the amphetamines code group, methamphetamine was reported as the principal drug of concern in just over 2 in 5 episodes (44%) in 2014–15, rising to 65% in 2015–16, 74% in 2016–17, 79% in 2017–18 and 83% in 2018–19 (Figure 10a). The rise in episodes where methamphetamines was the principal drug of concern could be related to increases in funded treatment services and/ or improvement in agency coding practices for methamphetamines
- the proportion of treatment episodes where cannabis was the principal drug remained consistently higher than the national proportion, peaking at 40% in 2015–16 in Queensland, compared to a national peak of 24% in 2013–14 (Table SD.2).
