Edibles

How many days does it take before you can drive and test negative after having edibles.

I’m aware how long it stays in your system but how many days for the general drug/alcohol when driving pls.

Google says 3 days but wanna make sure. Has anyone experienced something different ??

(Asking for a friend. Serious answers only and no judgement pls it’s not for me)

I live in Australia if that helps understanding the protocol ?
