Tested positive NSW

Anyone know the go?

Got pulled up on the way home from dinner in Sydney with my mate and tested positive yet hadn’t smoked for 2 days during my T break (ironic). Firstly tested false positive for alcohol apparently over the legal limit, taken to the van for further testing and blew 0s on the secondary RBT. Get told after I have to submit two drug tests, cannabis shows up and here we are.

Police said it’ll take the lab about 5-6 months for results to even come back but also let me know since it was my first offence I’d only be getting a fine and 3 months no license with zero conviction??? Is this cop full of shit or am I tweaking?

lol happy Wednesday. Ffs
