Getting grandma drunk has always been a past-time that kids have been on board with, but getting her stoned is another thing.

But that’s what happened to this grandmother when she ate her grandson’s hash-brownies without realising they were laced with weed.

He said: ‘My grandmother ate my edibles, I’m crying!’

Inevitably the giggles kicked in and he filmed her as she sat in her black leather recliner trying to get hold of her drink from the cup holder.

But she was unable to get to it and sat back singing away to herself.

She then bursts out laughing again as she reaches to get her glass, using both hands to drink it and manages to take a cautious sip.

Eventually she calms down a bit as she sways in circles and starts humming away to herself.
