Spain drug laws
Laws on research chemicals in Spain
The rules here regarding RCs are basicly the same as in the UK, the only difference is that laws on scheduling substances will be passed later than in the UK: usually a few months to a year after a UK ban is in place (e.g mephedrone & methylone). The use and posession of any, even scheduled, subtances, within the premises of ones own home is decriminalized and not punishable by law. For more information check the UK drug laws section.
