We've seen a lot of unexpected, and sometimes cool, iPhone apps approved by Apple, but today's news might top the rest. Apple has approved a marijuana -- that's right, marijuana -- app called "Cannabis," which lets users find the nearest (don't worry: legal) supplier of medicinal marijuana.

Created by the founder of Ajnag.com, which was founded in 2006 and was the first medicinal marijuana locater on the Web, the new app is quick and easy to use. Simply open it up on your iPhone or iPod Touch and you'll see a map with the nearest distributors. The app gives you information on each of the locations, and even step-by-step directions with Google Maps.

That's not all, though -- the creators thought of everything. If you run into any, erm, legal troubles with your newly-secured marijuana, Cannabis also gives you the locations of the nearest lawyers who specialize in marijuana cases. And, if you happen to live in one of the 37 states where marijuana is not legal, the app also provides you with the location of the nearest marijuana activist groups -- so you can do your part to promote reform.

Cannabis provides the locations of legal marijuana locations in the 13 states where medical marijuana is legal, as well as in the parts of Europe where marijuana use is legal.

It will not point you to your local dealer in Golden Gate park or to the nearest White Castle, though, so potheads should save themselves the $2.99 download fee.

But, if you're a legitimate user of medicinal marijuana, and you often find yourself in situations where you absolutely must obtain some, then, good lord, get thee to the App Store!
