In all seriousness, who could have imagined that there are such large number of suicidal people in our society?

Treat it as a medical problem and get individual users completely out of the criminal law system.  Provide addicts (no joyriders) with free, laboratory grade drugs for consumption in supervised controlled sites.  Petty crime plummets.  Social costs (hospital, police, courts) plummet.  Spread of disease decreases.  Multiple opportunities to speak ;with the addicts and encourage them into treatment.  Where's the downside?
