Salad and sandwich chain Habitual Fix has been ordered to pull advertising for a smoothie, because the ads sounded as though the drink could get people high.

Ads for the hemp smoothie included slogans such as "Just ask your dealer," and "Don't panic, we also do munchies".

The $7.50 smoothies are a blend of hemp oil, cucumber, mint, yoghurt and apple juice.

The Ministry for Primary Industries ordered the change this week, telling the company to remove all health claims and drug references.

Habitual Fix owner Tim Benest says he's happy to comply and only used references so staff could point out there's no drug in the drink.
