Students banned from cannabis coffee shops 'more likely to pass exams,' Dutch study

The Independent 11 April 2015
Students who were banned from smoking legal cannabis in Dutch coffeeshops were found to be more likely to pass exams, specifically maths-based ones, according to researchers.

The findings were worked out during a temporary “partial-prohibition” of cannabis cafes in the city of Maastricht, in which people were not allowed to enter on the sole basis of their nationalities.
Students who were banned from the 13 coffee shops in the city have been 5.4 per cent more likely to pass their courses, economists at the University of Maastricht found.
The effect is “five times larger” for courses requiring quantitative thinking and maths-based tasks, the researchers wrote.
Lower performers – who had a pre-study GPA below the median of 6.62 – were most impacted by the ban with a 7.6 per cent increase in probability of passing a course. This may be down to ‘high’ achievers already getting top grades, regardless of cannabis consumption, they added.
The study comes after 20 US states legalised the use of medicinal cannabis and 14 others took some steps to decriminalise possession. Uruguay is planning to become the first nation in the world to fully legalise all aspects of the cannabis trade.
