Annex E Terms f Reference: Therapeutic use The purpse f the pre-review reprt is t synthesize existing scientific evidence abut the therapeutic use and ptential fr dependence and abuse f cannabisrelated cmpunds Any recmmendatins n the scheduling f the substances are t be made by the Expert Cmmittee, and shuld nt be included in the pre-review The WHO pre-review reprt template 1 fr substances under review by the Expert Cmmittee n Drug Dependence cmprises five scientific tpics: Chemistry Pharmaclgy Txiclgy/ Adverse Effects Epidemilgy Therapeutic Use The authr will cmplete the Pre-Review reprt fr the scientific tpic f therapeutic use based n the template fund n Annex Page 7 The authr will prepare fur separate Pre-Review reprts n the therapeutic use f the fllwing cannabis related cmpunds: Reprt 1: Cannabis plant and cannabis resin Reprt 2: Extracts and tinctures f cannabis Reprt 3: Delta-9-tetrahydrcannabinl (THC) Reprt 4: Ismers f THC Where authrs refer t a specific cmpund (e.g. type f cannabis plant, extract, r ismer), they are asked t clearly indicate this in the reprt The Pre-Review reprts will be prepared in accrdance with the specific inclusin and exclusin criteria t minimise verlap and repetitin f infrmatin (Annex Pages 3-6). The Pre-Review reprts shuld include infrmatin, where feasible, in all the required sectins f the template in accrdance with the Guidance n the WHO review f psychactive substances fr internatinal cntrl dcument. The guidance dcument is available nline at the WHO Expert Cmmittee n Drug Dependence website: http://www.wh.int/medicines/access/cntrlled-substances/ecdd/en/ The Pre-Review reprts shuld be presented in a manner that will facilitate an evidencebased assessment by the Expert Cmmittee. The Pre-Review reprts shuld be written in an bjective manner withut bias r pinins. 1 Pre-review: An initial review t determine whether a critical review is warranted. If the Expert Cmmittee finds the infrmatin may justify scheduling r a change in the scheduling f the substance they can recmmend a Critical Review. A critical review is t cnsider whether the Expert Cmmittee shuld advise the Directr-General t recmmend the scheduling f, r amending f the scheduling status f, a substance. 1
The Pre-Review reprts shuld summarise the literature in a manner that presents the relevant infrmatin, withut necessarily prducing an exhaustive reprt. The use f existing reviews is encuraged, prvided adequate referencing is utilised. Preliminary drafts shuld be submitted t the WHO ECDD Secretariat fr assessment f quality and suitability fr the Expert Cmmittee. The Secretariat may request editrial changes and fllw up drafts, if deemed necessary. The final draft f the Pre-Review reprts will be peer-reviewed by experts frm WHO s Expert Advisry Panels. This will include an evaluatin f the strength f evidence presented. If there are data limitatins r missins, they will be discussed with, and adapted as needed, by the authr. Examples f previus pre-reviews are available n the WHO Expert Cmmittee n Drug Dependence website. Fr example, tw pre-reviews (phenazepam and etizlam) were prepared fr the 37 th ECDD in 2015. Authrs shuld include a cmprehensive list f references, and specify the methdlgy used in the reprt 2
