A member asked:
Has it been proven that marijuana improves night vision?
A doctor has provided 1 answer
Field studies: There are some field studies of jamaican fishermen and also some moroccan fishermen and mountain dwellers, pointing to improved night vision with marijuana smoking. The effect seem dose-related, and further study was suggested. This is not "proof, " though. http://science.iowamedicalmarijuana.org/pdfs/misc/russo%20et%20al.%20cannabis%20night%20vision%20jep%202004.pdf.
