Wanted: Marijuana Smokers For University Study

At the University of Iowa, a group of scientists are looking for people to smoke pot as part of a study to help gain some ideas concerning marijuana's effect on brain function using brain imaging studies and achievement tests as a guide.

Robert Block, associate professor of the universities Department of Anethesia, said the scientists are looking for both pot smokers, and people who don't smoke pot, but may consume alcohol and tobacco for the study.

Subjects will get $20 for an initial screening, with $600 for their full participation. The findings might be used to support whether marijuana should be decriminalized, used for medicinal purposes, or if harsher criminal penalties should apply.
