Meh what this study doesn't take into consideration is dependent memory states or differential memory states. If you learn something while high, then you often need to get high again to be able to remember it. This happens with everything from antidepressants to alcohol. Why this is always overlooked for cannabis I don't know. For example, if someone where to study high, then get high before taking their test they might perform equally to the sober group or possibly even have improved performance. I know there have been many times when cannabis actually improved my cognition like this in certain circumstances. Anyone who uses cannabis regularly will experience this, so of course if you stop using it completely the testing metrics they use to measure cognition will improve as the sober group becomes more sober their ability to remember what they've learned while sober will improve since they're no longer oscillating between different memory states. What would be really interesting is to take a control group who continues to use cannabis and see how they compare to the kids who you make stop using it. If their cognition remains stable and on par with the sober group with continued use then does this study really mean what they think it means? This study is also limited to THC, which means they're only studying 1 cannabinoid and not the whole plant and how it works with CBD and other cannabinoids. From experience I can tell you that CBD counters many of the negative side effects of THC, as it functions as a neuro-protectant and anti-inflammatory. Had they tested against a variety of cannabinoids and measured which cannabinoids had what effects and then studied the using groups vs. the sober group and how they performed then you could come to a more conclusive argument.
