I had this idea that it would be a perfect disguise to hide your drugs in like a can of pepsi or something and crush it, then move it away from your house, bury that can in the woods somewhere, if someone finds this can they'll probably think it's rubbish and throw it away, most times people don't just pick up rubbish open it and then say "oh there's 1g of coke".
I would think that the best way to hide anything is to blend it into the environment it's in, it's got to look like something that's naturally there, then nobody can find it as they overlook. There is rubbish all over the streets, so it fits in.
Hobos like to return recyclables.....no one ever picks up used condoms.
