To ask the Secretary of State for Health what assessment he has made of the clinical effectiveness of ibogaine in treating drug addiction; and what funds are available for further trials. 
No specific assessment has been made on the clinical effectiveness of this drug. It is not licensed for use in the treatment of drug dependence. Licensing of medicines in the United Kingdom is determined by science. The same standard of safety and efficacy would be required for ibogaine as for any other medicine.
