Methamphetamine users in WA could be locked up in crisis accommodation centres as part of the McGowan Government's plan to reduce the use of the drug.

The WA Government has rejected to consider legalising some drug use, but Premier McGowan says reducing the stigma around drug use is also important.

The Government provided few details about the proposal for compulsory crisis intervention but said the legislative change could be required and further consideration would also be needed before it was implemented.
