I believe this is akin to "people who drink x% a day have no problems", it's _static_. What it totally ignores is that the addictive substance subtly changes behavior over time and x% of those people go on to become full blown addicts.
Of course, alcohol guidance levels have been way too high for decades now, most modern orgs suggest less than 2 a week, and even use verbiage that states anything near or above 2/week increases health risks of all types - with zero upside. A dramatic difference from alcohol guidelines of yesteryear proclaiming a glass a day will improve your heart or whatever BS.
So this idea that full blown addicts are created by people who take a glass per week (the actual recommendation, not the alcohol industry funded one) or whatever is absurdity. Why were they using the substance in the first place? This will be a much bigger determining factor to their outcome - much like you can tell who social media is going to drastically affect by whether or not their support system embraces them.
Great point, I had not heard that before.
