I was thrown off by this definition of "marijuana-years" seemingly being used as the base of the study, when we then read this:

>> Few people actually smoke this much pot. Among the 3,385 study subjects, only 311 (8 percent) had more than five marijuana-years of exposure.

The article makes an assumption about how much one's memory would be affected by 45 years of smoking... but if only 311 participants have smoked for even 5 years, it is logically unsound to even pretend to extrapolate that to 45 years.

Why do studies (or perhaps the study itself makes none of these conclusions, and it's just the article) try to overreach on their conclusions? :/
