Its going to come back to reasonable grounds. Lets say there's a knock at the door and they have a warrant for your mate's arrest - would it not be of interest that he came so quietly and being so adamant that you didn't need to trash your place? What's that smell? The odour of cannabis?
In theory, yep, shouldn't be a problem. In practice, it depends how bad they want to look in the house.
Just something worth considering, whether it is law or not in australia. A mate got himself convicted for growing weed indoors, how he got caught was still questionable.
Mate had just moved into a new house/rented, staying for 2 months, started a grow, next thing police are at front door with search warrant for previous tenant! even though mate showed them his tenancy agreement with his name on it and not the previous tenants. They stated a law where they can search a house to make sure that the person wanted is not hiding in 'the waredrobes' and such!!
So yep he got busted, after all that it was just a $400 fine, but anyhow quite cunning if you ask me!
p.s. awesome work fortehlulz!!
