(en) Brendan Hughes, « New Czech penal code enters into force », sur Drugnet Europe, Drugnet Europe, (consulté le ) : « the new penal code criminalises the cultivation or possession of an illicit drug for personal use when the quantity is ‘greater than small’. However, the new code now establishes quantity limits via a binding governmental decree (No 467/2009 Coll.) (2). For example, it stipulates that a crime is committed on possession of more than 5g of cannabis resin (previously 10g), 15g of herbal cannabis or 1g of cocaine, and on cultivation of more than five marijuana plants. »
