It's irrational to legally tolerate one set of deadly addictive substances(alcohol&tobacco) while hypocritically demonising&criminalising another set of popular substances&their persecuted users.

Alcohol prohibition only served to make the mafia rich, powerful,&more violent. People continued to drink in huge numbers,despite alcohol's illegality. NY City alone had 5,000 illegal speakeasies during prohibition.Prohibition also made booze more dangerous than it otherwise would be.  1,000 Americans died each year during prohibition from toxic booze,typically incorrectly distilled hard liquor with deadly methyl, instead of ethyl, alcohol.

We see the same pattern of failure with drugs prohibition.Drug gang ultra-violence, heightened OD risk from unregulated black market drugs of uncertain content,property crime by addicts paying artifically sky-high black market prces for substances dirt cheap to produce, - all these serious & worsening problems are created by prohibition, not drugs.End it.
