Yeah although this is more a consequence of how SF decided to handle it. Rather than decriminalising they're just enabling users. Look towards other countries

Yeah although this is more a consequence of how SF decided to handle it. Rather than decriminalising they're just enabling users. Look towards other countries with similar policies (Portugal, Netherlands, etc.) in their cases they saw a decrease in drug usage and fatalities. The difference is they decided to not encourage their behaviour by allowing open air drug markets to flourish, with kiosks just down the street handing out the necessary paraphernalia.
