For very specific historical reason. Opium was devastating in every possible way for China and part and parcel of semi-colonialism. Brazilians have a different historical context where drug enforcement has been devastating for poor Brazilians: it’s been a way to socially and economically oppress the poor. It’s not about if drugs are bad for people - they are. It’s about the criminalizing, law enforcement, who’s being targeted and what are the consequences and casualties. So the departure point is different. The left in Brazil is caught in a harsh cycle (I’m inferring) - needs to formulate a transitional demand around drug criminality that would garner support immediately and also in the future lay the groundwork for eventual social and economic development which would hopefully lead to dismantling the drug industry and give people productive jobs and a good life. The beauty of Chinese revolution is that it didn’t apply (or stopped applying) what worked in the Russian revolution and Europe when it wasn’t working for China and created their own specific political lines and strategy that led the to a successful revolution. The method of understanding reality and that informing practices are most important to learn from each other.
