The ACT Government has sent a letter to the Commonwealth warning against overturning new cannabis laws, calling the laws the “will of the people”.

Senior federal ministers have criticised the ACT’s decision to legalise the possession, consumption and cultivation of small amounts of cannabis for adults in Canberra since it was announced last month.

The ACT attorney-general Gordon Ramsay said in the letter that the government did not condone the recreational use of cannabis but the laws are necessary to avoid “needless criminalisation”.
