Chief minister Andrew Barr describes the Australian Capital Territory’s decision to legalise cannabis possession for personal use as an “evolution, not a revolution”. The ACT law, to take effect at the end of January, will allow residents 18 years and over to possess up to 50 grams and grow two plants, up to a total of four plants per household. With the federal medicinal cannabis regime, introduced in 2016, still in its infancy, the ACT is ahead of the pack – one of only three jurisdictions where it is decriminalised, along with the Northern Territory and South Australia – and is now the first to legalise it.
