At least it's broadly kind of informative in description of some of the categories before the 'continued' section. That may seem a low bar but I guess efforts to educate on this topic have set such a drastically low bar in decades past that it's encouraging to see it lifted slightly off the floor. The categorisation scheme takes a bit of a nosedive when they get to marijuana which for some reason has its own category, also for all the drugs and categories they describe they make the mistake of failing to describe the effects that make people want to use the drugs in the first place. I can see why they might be hesitant to do that, you don't want to actively encourage people to use the drugs, but I remember when getting similar lessons on the topic thinking that it was an obvious omission because it's hardly like people took the drugs, repeatedly, because of how much they enjoyed the "impairment" especially as I has my own first hand experience running directly counter to it. The failure to address the positive sensations taking such drugs produces that have caused people throughout all of human history to seek drugs out, damages the credibility of the information since it clearly sought to discourage at the cost of objectivity.
