Spain was one of the first modern European countries to decriminalize marijuana -- and one of the last to implement needle exchanges. The Spanish government paid a steep price for their initial reluctance to allow harm reduction measures. Spain has the highest HIV rates in Europe among intravenous drug users. These days needle exchanges - including needle exchanges in prisons - pill testing at raves, methadone maintenance and heroin maintenance trials are among the many public health interventions that are supported by autonomous regions throughout Spain. Drug use and possession for personal use do not constitute a criminal offence under Spanish law. However, public consumption is penalized with administrative fines.

Spain’s marijuana policy is rather unique in that it encourages marijuana smokers to grow their own product. Personal consumption and home cultivation have been decriminalized, but buying or selling marijuana/hashish remains a criminal offense.
