The Australian Capital Territory law to legalise cannabis possession appears to “do nothing to end the continuing operation” of commonwealth offences, Christian Porter has warned. The attorney general’s comments suggest Canberra cannabis users will be left in legal limbo when the laws take effect from February, contradicting the ACT government’s claim that its law provides a defence to the federal offence. The Morrison government has stepped up its rhetoric against the laws. Health minister, Greg Hunt, accused the ACT government of being “blind and indifferent to the health consequences” of cannabis after asking it what medical evidence was considered before legalising it.
