Seattle has stopped charging people for personal drug possession
I lean heavily towards giving people the freedom to do what they want, but in 'private' and without burdening public life of others.  If people want to light up or shoot up, so be it.  But I think a community must have ways to discourage or push people out of the public sphere who practice unwelcome and unsocial behavior.  The gov't fully feeding, clothing, and sheltering large groups of addicts is impractical and unviable in most/all places.
