This is not true in the US. We have no politicians that are suspected of being involved with cartels.
While our policies might not help the situation, no politician is actually working with traffickers.
What I can say is it has happened here for a long time, and no one questioned as they were also in control of the media. Just until recently it became widely known the 20+ years of smoke of “fight against drugs”. Maybe over there is different, or maybe is not a big of a deal, as, even if there is a lot of money in drugs, there is orders of magnitude more money in big tech, and also from a cleaner origin, so who knows.
