Legal high bans and crime
From Scoop, in a press release on the legal-highs bill by Manurewa Local Board member Toa Greening
Ireland led the way by prohibiting all non-prescribed psychoactive substances back in 2010. This resulted in an immediate reduction in related psychoactive substance health issues and crime.
Irish data on recorded crimes is available throught the Ireland Official Statistics portal, Statcentral.ie. This graph shows quarterly data since 2004 for the main crime categories (the heavy blue line is drug offenses, and the vertical line is when the ban came into force)
I don’t see any dramatic effects of the ban on any category of crime.
