John Schwarz, Theoretical Physicist and co-founder of Superstring Theory, speaks out in support of marijuana legalisation:

It reminds me of the great divide that developed between the then-ruling Catholic Church and the European public over the order of the cosmos in the 17th century. In 1633, the Church sentenced Galileo Galilei to lifetime house arrest for claiming that the earth revolves around the Sun rather than the other way around…

There are a few other people of note on that list supporting legalisation, too.

“80 years after the end of prohibition, prohibition is finally coming to an end.”
