For anyone who may be excited about the recent legalisation of marijuana, thinking it may reduce your risk for a common type of eye disease – this news may not be too thrilling. Recent studies at the University of Indiana showed that two components of marijuana (CBD and THC) did not behave as expected when eye pressure was measured.
High eye pressure is a risk factor in glaucoma – a disease that causes progressive loss of peripheral vision if untreated. It was widely believed that marijuana decreased eye pressure and therefore lowered the risk of vision loss from glaucoma. The recent study showed that while THC did decrease eye pressure, this was counteracted by CBD and actually caused a rise in eye pressure.
