Apologies if this has been posted but ran across an article where someone was busted with $40 worth of heroin. Charged with distribution and his parents home, with whom he lived, was seized! Sounds like even before a trial!

sounds like the possession charge was just the straw that broke the camel's back and that police had been working on a much bigger overall case for a while for them to be able to seize the house. the kid was probably moving weight out of there and just happened to only get caught with $40 worth.
