Num momento em que décadas de progresso nas políticas de drogas enfrentam uma maré conservadora global, o neurocientista brasileiro Sidarta Ribeiro publica em Portugal uma obra que convoca a ciência e a linguagem acessível para defender a regulação racional da cannabis. Portugal, que em 2001 inaugurou um modelo legislativo admirado no mundo inteiro, serve de prova viva de que é possível tratar a questão com responsabilidade — mas também de alerta sobre o que pode ser perdido. Ribeiro acredita que o arco longo da história aponta para a liberdade e a evidência, mesmo que as forças da regressão c

Advocacy framing that positions cannabis decriminalization as progressive 'rationality' versus conservative 'reactionary' forces; Portugal's policy presented as unambiguously successful model without critical examination.

Ideological struggle between progressive drug policy reformers (academia, some governments) and rising conservative/reactionary political movements. Portugal positioned as policy leader; Brazil's scientific community advocating for rational approaches against domestic conservative forces. Reflects broader global polarization on social policy.
Similar to 1970s-80s drug policy debates where scientific evidence gradually shifted public opinion against punitive approaches, though current reactionary wave mirrors earlier prohibition-era resistance to evidence-based reform.

Consumers face policy uncertainty regarding cannabis access, pricing, and legality. Decriminalization could reduce legal costs and stigma, improving healthcare access for medical users. However, reactionary political movements may restrict availability and increase prices through continued prohibition.
Governments may face pressure to either advance evidence-based cannabis regulation (following Portugal's model combining decriminalization, education, and social reparation) or reverse course under conservative political pressure. Policy stability is critical for market development. Potential regulatory frameworks could include medical licensing, taxation, and social equity programs.
