Apple has pulled the popular iOS game called Weed Firm from the Apple App Store, after it climbed to the top of the download charts. The app lets users sell and grow virtual marijuana.

The game, which is intended for adults, puts you in the shoes of botany student Ted Growing, who manages a weed-growing operation. Users are responsible for finding ways for it to grow faster over time, overcoming obstacles with police and gangsters and customizing the home to make it inviting to guests.

"This was entirely Apple's decision, not ours," developer Manitoba Games said in a statement on its website. "We guess the problem was that the game was just too good and got to number one in All Categories ... There are certainly a great number of weed-based apps still available, as well as games promoting other so-called 'illegal activities' such as shooting people, crashing cars and throwing birds at buildings."

The Android version of the app was removed from the Google Play store because of a publisher issue, not because of the game's theme.

"When your customers come knocking, treat them well," a promotional YouTube video for the game declares. "Smoke a joint with them to change their behavior. Sell them weed to make cash. You can also tell them to piss off."

The company plans to bring the app back to iOS by censoring some of its content, but other marijuana-focused apps continue to live in the App Store, such as Weedmaps.

"We do not want kids playing Weed Firm, but we firmly believe that adults should have a choice to do whatever the hell they want as long as they are not hurting anybody in the process," the statement reads.

Manitoba Games said it is launching a sequel later this year with new characters, improved graphics and magic mushrooms.
