When the police takes drugs and weed from people what do they do with it ?

My best friend's dad was a cop. Highway patrol seized a car full of marijuana that had been driven up from Miami or some shit. Legally, once it's use as evidence was expended, they had to dispose of it, so they all got together and set it on fire and stood around in the smoke. According to him, that is.

evidence and then destroyed at an appropriate time

what police are you talking about? there's thousands of police corps throughout the world

They claim it goes in the evidence room, but what you're suggesting is a possibility. Wouldn't surprise me.

Report half of quantity seized and smoke the rest.
