The whole point is that the science isn't really saying much. The author of the study doesn't even assert that these brain changes are bad. It's people's interpretation of science that can be bent. As I said earlier, there's no way to infer causality in this study.

quit supposing. Lots of ridiculous claims in the article/study

Breiter hailed the study as the first to analyze the effects of light marijuana use.

The study analyzed 20 pot smokers and 20 non-pot smokers between 18 and 25. Scientists asked them to estimate how much marijuana they smoked and how often they lit up over a three-month test period. Even those who smoked once a week showed brain abnormalities, while larger changes were seen in those who smoked more.

No way that could possibly be inaccurate or a poor representation of the population

The study did not look at the behavior of the pot smokers, only their brains. What effect, if any, Wednesday’s findings will have on future legislation remains unclear.

“Drugs of abuse can cause more dopamine release than natural rewards like food, sex and social interaction,” said lead author Jodi Gilman. “In those you also get a burst of dopamine but not as much as in many drugs of abuse. That is why drugs take on so much salience, and everything else loses its importance.”

It said earlier that his study didn't touch on behavior. That isn't what I would call I scientific conclusion. Even if the study were done correctly and was accurate, that conclusion would be out of the scope
