Translate the following English sentence to French:
"In this case, there are a few basic principles which I feel must guide our action: we must act fairly against all factors likely to cause addiction, such as advertising and excessive consumption of dangerous pharmacological substances - funded, moreover, from the social security system -and we must ensure that restrictions on tobacco production within the Union are accompanied by the monitoring and restriction of imports so that their effects on consumption are not cancelled out. We must give tobacco growers an adequate timescale in which to adapt their production to the new standards for tar content and we must reject any restriction on subsidies for tobacco production unless we replace them with aid as an incentive for conversion."
En l'occurrence, quelques principes simples me semblent devoir guider notre démarche : agir équitablement contre tous les risques d'assuétude, y compris contre la publicité et la consommation immodérée - financées de surcroît par la sécurité sociale - de substances pharmacologiques dangereuses ; faire en sorte que la limitation de la production intérieure de tabac soit assortie d'un contrôle et d'une limitation des importations afin de ne pas en annuler les effets sur la consommation ; accorder aux planteurs un délai approprié pour adapter leur production aux nouvelles normes relatives à la teneur en goudron ; refuser toute limitation des subventions à la production du tabac sans leur substituer des aides incitatives à la reconversion.
