Within the context of logic, that is not an implication.

You know what I hear when a product is touted as being "in the top 10"? That it's definitely somewhere between #6 and #10. Because if it was 3rd, it'd be "top 3", and if it was 5th, it would be "in the top 5".
If a pull quote or headline shows a good statistic for one cohort, it's a fair bet that other cohorts didn't show such a positive result, or else the touting would have been something like "overall" rather than "15–24".
Within the context of logic, you cannot imply anything about other cohorts from this one statement alone. However, if general population use remained steady or rose, it would definitely imply that fall is attributable to said cohort.
Does the article have anything to say about general population?
> "While drug use during individual lifetimes among the general population appeared to increase in the decade following reform,"
No, but it is within context of narrative crafting practices. If it fell across all age groups, they would have said so, instead of restricting their claim to narrow group of youths. To misunderstand it is either sign of extreme naivety, or willful ignorance.
By your same logic, if it rose, they would have said so. They didn't.
Perhaps it was unchanged meaningfully / statistically significant enough to comment?

No, because they aren’t uninterested, unbiased observers just reporting the facts. The entire linked article is pushing very specific policy, and it is only expected that they will only raise arguments in favor of the policy they are proposing.

No. I looked at the data, and reported it accurately. Drug use went up overall, and if you disregard drop in heroin use (though only among young people, it also went up among those 35+), use increased significantly. Drop in heroin use among youth has offset the growth in use of other drugs.
