Legal distinctions are made in the Opium Law between drugs with a low risk of harm and/or addiction, called soft drugs, and drugs with a high risk of harm and/or addiction, called hard drugs. Soft drugs include hash, marijuana, sleeping pills and sedatives, while hard drugs include heroin, cocaine, amphetamine, LSD and ecstasy. Policy has been to largely tolerate the sale of soft drugs while strongly suppressing the sale, circulation and use of hard drugs, effectively separating it into two markets. Establishments that have been permitted to sell soft drugs under certain circumstances are called "coffee shops". Laws established in January 2013 required visitors of coffee shops to be Dutch residents, but these laws were only applied in Zeeland, North Brabant and Limburg after much local criticism. Possession of a soft drug for personal use in quantities below a certain threshold (5 grams of cannabis or 5 cannabis plants) is tolerated, but larger quantities or possession of hard drugs may lead to prosecution. Prosecution for possession, trade and (in some rare cases) use are typically handled by the municipal government except where large-scale criminal activity is suspected.
