 on behalf of the Department of Health. The position in the member states of the EU is not harmonized. Member states have implemented the relevant UN Conventions (the Single Convention of Narcotic Drugs 1961 and the Convention on Psychotropic Substances 1971) into their national legislation, which has led to differences in how controlled substances are regulated in different countries of the EU. It is therefore important to determine at a national level whether a substance is controlled and to comply with the applicable legal requirements. If we are successful in obtaining a marketing authorization in key EU member states, it is likely that rescheduling of mebufotenin will also be required to enable prescribing. There can be no guarantee that such rescheduling would be successful. In the UK, where part of our manufacturing process takes place, mebufotenin is considered a Class A drug under the Misuse of Drugs Act 1971, as amended, and as a Schedule 1 drug under the Misuse of Drugs Regulations 2001, as amended. Class A drugs are considered to be the most potentially harmful and have the highest level of control exerted over them under the Misuse of Drugs Act 1971. Similarly, Schedule 1 of the Misuse of Drugs Regulations 2001 lists those drugs to which the most restrictive controls apply: they are considered to have no legitimate or medicinal use and can only be imported, exported, produced and supplied under a license issued by the UK Government’s Home Office. If and when it is granted a marketing authorization by the MHRA in respect of the UK, mebufotenin would still remain a Schedule 1 drug until rescheduled by the UK Government’s Home Office. Unless and until mebufotenin is rescheduled under the Misuse of Drugs Regulations 2001, and unless a statutory exemption was to be passed for GH001 or GH002 following the grant of a UK marketing authorization and before rescheduling, any prescribing doctors in the UK would require a Home Office license to prescribe GH001 or GH002, and, similarly, any patients to whom GH001 or GH002 was prescribed would require a Home Office license to possess GH001 or GH002. There can be no guarantee that such Home Office licenses would be granted or that rescheduling would be successful. Regulatory Requirements After Marketing Authorization Following approval, the holder of the marketing authorization is required to comply with a range of requirements applicable to the manufacturing, marketing, promotion and sale of the medicinal product. These include compliance with the EU’s stringent pharmacovigilance or safety
