Africa-Press – Madagascar. <\/strong> <\/span>Vu le manque de preuves, il est difficilement justifiable a\u0300 l\u2019heure actuelle d\u2019employer couramment des cannabinoi\u0308des pour traiter des troubles mentaux ou lie\u0301s a\u0300 l\u2019usage de substances (addictives) \u00bb, conclut ce travail paru dans le Lancet Psychiatry. Le cannabis me\u0301dical est actuellement autorise\u0301 dans plusieurs dizaines de pays, comme l\u2019Australie, le Canada ou plusieurs Etats de l\u2019Union europe\u0301enne, essentiellement dans deux grandes indications: face a\u0300 la douleur et a\u0300 certaines troubles psychologiques.<\/p>\n

Ces donne\u0301es sont \u00ab en ge\u0301ne\u0301ral de faible qualite\u0301 \u00bb<\/p>\n

L\u2019analyse du Lancet Psychiatry, qui vise a\u0300 compiler l\u2019ensemble des recherches disponibles sur le sujet, se concentre sur le second volet. Ses auteurs, emmene\u0301s par le chercheur australien Jack Wilson, dressent un tableau pour l\u2019heure peu concluant. Certaines donne\u0301es laissent penser que les produits dits cannabinoi\u0308des \u00ab peuvent ame\u0301liorer \u00bb des sympto\u0302mes allant des tics a\u0300 l\u2019insomnie en passant par une addiction au cannabis lui-me\u0302me, constatent-ils.<\/p>\n

Mais ces donne\u0301es sont \u00ab en ge\u0301ne\u0301ral de faible qualite\u0301 \u00bb, pre\u0301viennent-ils, notant toutefois que le cannabis me\u0301dical ne semble pas associe\u0301 a\u0300 des effets secondaires graves dans ces indications. Selon l\u2019e\u0301tude, cela ne signifie pas qu\u2019il faut conclure a\u0300 une absence d\u2019inte\u0301re\u0302t du cannabis me\u0301dical dans les troubles mentaux, mais qu’ \u00bbil y a un besoin pressant de recherches d\u2019excellente qualite\u0301 \u00bb pour re\u0301ellement pouvoir le recommander.<\/p>\n

De nouveaux pays envisagent de le\u0301galiser le cannabis me\u0301dical<\/p>\n

A titre de comparaison, dans les indications lie\u0301es a\u0300 la douleur, une e\u0301tude du me\u0302me type, publie\u0301e en 2021 dans le BMJ, avait conclu a\u0300 des effets positifs, mais seulement \u00ab le\u0301gers a\u0300 tre\u0300s le\u0301gers \u00bb. L\u2019e\u0301tude du Lancet Psychiatry s\u2019inscrit dans un contexte ou\u0300 de nouveaux pays envisagent de le\u0301galiser le cannabis me\u0301dical mais ou\u0300 son inte\u0301re\u0302t continue de faire de\u0301bat au sein du corps me\u0301dical.<\/p>\n

En France, le gouvernement envisage depuis plusieurs anne\u0301es d\u2019autoriser des traitements a\u0300 base de cannabis, principalement dans la douleur mais aussi dans certains troubles psychologiques chez des personnes atteintes de cancer, comme l\u2019insomnie. Une expe\u0301rimentation a e\u0301te\u0301 mene\u0301e au de\u0301but des anne\u0301es 2020 mais, a\u0300 la suite de plusieurs contretemps, ces traitements ne sont pas disponibles sur le marche\u0301 a\u0300 l\u2019heure actuelle, une e\u0301valuation e\u0301tant en cours par la Haute autorite\u0301 de sante\u0301 (HAS). Ses re\u0301sultats sont attendus a\u0300 l\u2019automne.<\/p>\n
