A dramatic increase in the number of lunatics in the Sengerema district of Mwanza region in Tanzania is partially being blamed on increased use of marijuana (as well as liquor). There were 290 lunatics in the area in December of 2007 and has risen to 413 lunatics just seven months later, in July 2008.

The article in Tanzania’s The Citizen newspaper goes on to mention that there is a “widespread belief amongst the residents” that witchcraft is responsible as well.
