the title says "drug users use a lot of drugs". either it's shamelessly clickbaiting or it's what the author thinks. we move to the ketamine section, again, "two studies on users". one clicks on the chinese one and the word "chronic" is in the title. the study focuses on them only. the english one is on "addiction research" but the study is more complex than this dude's summary. he says that "both find that they [the users] take about 90mg". this is, of course, not what the UK paper says, as one can check in the paper.

and to your point: some places have draconian laws about possession of MA in the same amounts that get prescribed in the US. if i were from thailand i would argue that this person is shamelessly drugging his patients.

there is nothing wrong with telling the truth about occasional recreational use, and yes, "drug addicts use a lot of drugs". that's a necessary condition for "addiction".
