Mary Jeaven is short for Mary Jane Heaven, I think it's pretty self explanatory. It's the place you go when you smoke Mary Jane. It's pretty much a religion of smoking herb. Every time you smoke, you go to Mary Jeaven. Good smokers (religious smokers) go to Mary Jeaven, Bad smokers (non-religious smokers) go to Mary Jell!
