Since 2003 a number of NPS have been placed under control in Sweden. The Narcotic Drugs Control Act (1992:860) is the legal basis for scheduling narcotic drugs in Sweden.
Other laws related to domestic control of narcotic drugs are:
- The Narcotic Drugs (Punishments) Act (sometimes also translated as The Narcotic Drugs Act; Swedish: Narkotikastrafflagen, SFS 1968:64). Under Section 8 of this Act, narcotics refer to "any pharmaceutical substance or good injurious to health, having dependence properties or euphorizing effects", which the Government has declared to be ‘narcotic drugs’ within the meaning of the Act.
- The Narcotic Drugs Control Ordinance (SFS 1992:1554, statutory instruments to supplement the Narcotic Drugs Control Act which includes the list of narcotics).
- The Act (SFS 1999:42) on the Prohibition of Certain Goods Dangerous to Health (in force since April 1999) supplements the Penal Law on Narcotics (SFS 1968:64). This new act applies to goods that, by reason of their innate characteristics, entail a danger to human life or health and are being used, or can be assumed to be used, for the purpose of intoxication or other influence. The Act is not meant to regulate substances that are regulated in other ways: pharmaceutical products or drugs controlled by the Penal Law on Narcotics or the Penal Law on Doping Substances (SFS 1991:1969). However, products classified under this act can, after careful investigation, be transferred to the remit of the Penal Law (this has been the case fo4-MTA, in November 1999). Like in the case of the Narcotic Drugs Punishments Act, the list of controlled substances under the Act on the prohibition of certain Goods Dangerous to Health is published as an appendix to the Ordinance on the Prohibition of certain Goods Dangerous to Health (SFS 1999:58). The government decides to what goods the Act and the Law shall be applicable. BZP was added to the list of controlled substances contained in the Ordinance on the Prohibition of certain goods dangerous to health (SFS 1999:58) in 2003 (see SFS 2003:77) and later reclassified as narcotic in 2010 (see SFS 2010:1083); 2C-T-2 and 2C-T-7 were transferred to the list of substances controlled as narcotics in March 2004. Simultaneously 2C-I and TMA-2 were added to the list of substances controlled as narcotics (SFS 1992:1554); 4-AcO-DET, 4-HO-DET, 4-AcO-MIPT, 4-HO-MIPT were controlled under the Act on the Prohibition of certain Goods Dangerous to Health (SFS 1999:42) as from November 2005; ketamine was listed as a narcotic substance in 2005 (SFS 1992:1554); DOC and DOI were listed as narcotic substances in May 2007 (SFS 1992:1554). DOC was previously on the list of goods dangerous to health; Bromo-dragonfly was also included in the list of goods dangerous to health but since 1st January 2008 it is listed as a narcotic substance; mephedrone (added in 2008 to the list of good dangerous to health but since May 25 2009 reclassified as narcotic). Other NPS that have been added to the list of narcotics (SFS 1992:1554) include 4-FMP, CP 47,497, analogues C6, C7, C8 and C9; JWH-018; JWH-073 and HU-210.
In January 2015, the Government of Sweden amended their Ordinance Regarding the Prohibition of Certain Goods Dangerous to Health (SFS 1999:58) to include an additional 32 NPS (5F-AMB; 5F-MN-18; 5F-PCN; 5F-SDB-005; AB-FUBINACA; ADB-CHMINACA; ADSB-FUB-187; AM-1248; CUMYL-5F-PICA; CUMYL-5F-PINACA; CUMYL-BICA; CUMYL-PICA; CUMYL-PINACA; CUMYL-THPINACA; FAB-144; FUB-AKB48; FUB-AMB; I-AMB / MMB-2201; MMB-CHMINACA / MDMB-CHMICA; mepirapim; NM-2201; PX-1; PX-2; THJ-018; MDPBP; alpha-PBT; alpha-PVT; MPHP; 4Cl-alpha-PPP; alpha-PHP; alpha-PEP; Salvia divinorum plant) identified as harmful to health (effective 16 January 2015).
In 2016 and 2017, benzodiazepines such as adinazolam, cloniprazepam, zapizolam, desmethylflunitrazepam, and flunitrazolam, were placed under national control.
