These studies really don't tell us much. So people with mental disorders are more likely to use rec. drugs. Gee, I'm shocked. People abusive alcoholic fathers are more likely to be problem drinkers. Eating fast food may cause obesity. You know some things don't deserve a research grant.
On the contrary, they tell us a lot. You just seem unable to process the information.
" While each of our long term cannabis users performed their task of selective attention, we recorded the electrical activity of their brain. What we found was very interesting. We found that some impairments are associated with the frequency of cannabis use, how often people were smoking. The problem seemed to be a general slowing of information processing. People who were using cannabis more than three times a week were much slower in recognising information as being important, evaluating that information and making decisions to act on that information" -Dr Nadia Solowij
