Becoming a nun is not easy - the journey is a combo of strict self-discipline, (a lot of) sacrifice and tough training. Maybe the Bible forgot to mention it but becoming a nun also demands a thorough knowledge-bank of marijuana horticulture.
Not that I know of a nun who does weed, but 'The Sisters of the Valley' are the uber cool nuns who consider themselves nuns BUT are neither Catholic nor traditionally religious.
They cultivate weed according to the moon cycles and after they turn their harvest into remedies, they sell it online. Their organic products promise "to treat a variety of ailments including back pain, migraines and even hangovers, and each jar and bottle gets its own little prayer before being shipped for distribution."
God is definitely on their side.
