A lot of this is genuinely great. I particularly appreciated the openness of prior users and dealers discussing the impacts the drug had on their lives. Also, much of the background and history of why it became such a widely discussed and controversial issue was broken down with outstanding clarity.
I'm just a bit iffy on the conspiracy part, as alluded to in the title. It might well have been part of the whole package, but there's not as much evidence to back that kind of thing up, and it's not as striking as the segments that look at things like racism, crime, prostitution, and the media hysteria, because there are plenty more interview testimonies and stock footage to back that stuff up.
If the scope had been narrowed to focus on the truly impactful stuff, and the runtime ever so slightly extended to allow for some more detail in those areas, this could have been a great documentary.
As it stands, it's still better than most of the documentaries Netflix produces, and due to at least 80% of it being very compelling, I would still recommend it quite highly.
