Only once, when a student. It was given to me by future dh - I didn’t much care for it.
At 80 my mother smoked a tiny little spliff on a Caribbean beach. It was procured for her by Very Bad dds, who’d told her she had to try everything once.
It was soon after after dark, she’d already had a couple of rum cocktails, was laughing helplessly, and saying she didn’t know what on earth her neighbours would say.
Shortly after we returned home there was a family wedding where ‘Granny smoked a spliff on the beach!’ went round the room like wildfire - together with much mirth.
