Coronation Street favourites Jack and Vera Duckworth will be seen high on cannabis in a forthcoming episode of the ITV1 soap.
Jack and Vera are two of the soap's most popular characters
The long-running stars will eat hash cakes accidentally thinking them to be harmless chocolate.
They are given them by Maz O'Loughlin at a party on the allotment.
"Vera asks if they can have one of their chocolate cakes and when we see them again they're both high as a kite," a Street spokeswoman said.
The episode will be shown on 8 September and is being hailed as a "classic Corrie moment".
The pair - played by Bill Tarmey and Liz Dawn - will be offered ginseng beer from organic food fan Maz, but opt for the "chocolate cakes" instead.
"Jack can see cabbages moving and Vera is balancing a banana on her head, singing Carmen Miranda songs," the spokeswoman said.
"Vera asks if she can have the recipe and Maz lets her have it - and she even gives her a bag of her special spices."
