Students with legal access to pot perform worse

Students with legal access to cannabis perform worse academically than their fellow students whose access is restricted. That's what Olivier Marie, professor at Erasmus School of Economics, and Ulf Zölitz discovered in their study 'High’ Achievers? Cannabis Access and Academic Performance'.

Marie and Zölitz studied two groups of students in Maastricht since that city has barred most non-Dutch citizens from buying pot. Therefore they could easily separate the group with legal access to marihuana – Dutch, German and Belgian students – from the group of international students without access.

Their research showed that students who were restricted from buying pot were getting better grades and failing in fewer classes than the students who did have access to marihuana. ‘In line with how THC (tetrahydrocannabinol, ed) consumption affects cognitive functioning, we find that performance gains are larger for courses that require more numerical/mathematical skills’, the researchers write.
