'Roll Your Own' Joint-Making App Approved By Apple (PICTURES)

Here's an app we weren't expecting to see in Apple's App Store, given the company's stringent (albeit unpredictable) policies regarding the apps that it approves: "Roll Your Own," a free app that offers videos and over 70 photos to help you "master the art" of rolling, packing, and "crutches."

Roll Your Own promises to teach you not only the basics, but also more advanced rolling techniques such as the Crowd Pleaser ("Almost twice as long as the Classic & guaranteed to please the crowds!") or the Tulip ("A Dutch specialty that is sure to bring smiles!"). Based on 40 reviews, the app has four star rating.

Due to "frequent/intense alcohol, tobacco, or drug use or references," the app is only available for download by users over 17 years of age.

Apple has been far less tolerant of sexually suggestive apps--Apple CEO Steve Jobs reportedly said in an email that the iPhone and iPod offered users "freedom from porn"--and Apple removed thousands of R-rated apps from its Apple Store in a significant purge that occurred last year.
