Since there has yet to be a toxicology report released or any major details via an autopsy on how she died, it's pretty silly to jump the gun and try and make a debate about drug legalization tied to Huston's death.
TMZ says a lot of things..... sometimes they get it right, other times they get ahead of themselves and let rumors take over reality.
The only facts given to the public at this time is that she was found face down in her bath tub, and not responsive & that one of her staff members found her like that after a period of time of her not responding to the door.... there's also the report that prescription pills were around, but no illegal drugs.
So again.... what does Huston's death have to do with legalizing street drugs?
