"Police and Public Prosecutor give low priority to the investigation of possession of small amounts of a drug for own use. The Opium Act Directive of the Public Prosecutor state that, if the offence concerns possession of small amounts for own use of a hard drug, the drugs will be seized, but normally there will be no custody or prosecution. Diversion to care is the primary aim of custody or prosecution in cases of possession of hard drugs (Directive Opium Act 2011A021 2012, www.om.nl). ‘Small amounts’ of a hard drug are defined as one tablet, ample, wrapple or ball of the drug and in any case an amount of no more than 0,5 grams. With regards to cannabis (categorized as ‘soft drug’) small amounts are defined as no more than 5 grams and no more than 5 cannabis plants – under the condition that there is no professional or commercial cultivation of the plants (Stc. 2011 – 22936). For hallucinogenic mushrooms, also categorized as soft drugs, the small amounts for own use are defined as 0,5 grams (dried mushrooms) and 5 grams (fresh ones). In cases of possession of small amounts of soft drugs, the drugs will be seized but a dismissal by the police will normally (‘in principle’) follow, without custody or prosecution."
