A friend was bragging once about regularly receiving ounces of bud from British Columbia in packages that contained no return address. He felt he was safe as he had no control over what mail he receives, and if busted he would turn it over and claim to know nothing about it.

I was curious so I mailed a couple of grams of hash to my home address with a fake name to see if it would be delivered. That was ten years ago. Maybe it's just lost in the mail and I'll get it when I'm eighty.
