A wedding descended into chaos after cupcakes were spiked with cannabis - leaving one grandma unconscious for 12 hours.
The guest in her 60s became "grey in colour" after tucking into the sweet treat at the family celebration in Torquay, Devon.
Another attendee also fell ill after eating the laced cake and was rushed to hospital.
The gran, who asked to remain anonymous, said the cupcakes had been unknowingly spiked with cannabis and caused chaos at the wedding.
She said: "My sister-in-law told me afterwards that she'd had trouble finding my pulse and that I was grey in colour.
"I was completely oblivious to what was going on until I woke up at 3am the following day at the hospital.
"In-between the wedding and the reception, cupcakes were randomly placed on the table. Unbeknown to me, they contained drugs.
"Had I known that, I never would have touched one."
Another guest, who had also consumed one of the cakes, fell ill and was later hospitalised.
The gran's sister-in-law was on the brink of performing CPR on her when the paramedics and ambulance arrived.
Reflecting upon the ordeal, the gran added: "I was okay one minute and then the next, I said to one of my family members 'I don't feel very well' - that's how quickly I fell ill.
"A young child had been about to pick up one of the cupcakes, but fortunately the child's parents had just managed to stop them from consuming the cupcake, which could have been devastating.
"It's horrific to think that the perpetrator sat and watched all of this unfold, and then just disappeared with no accountability.
"You never think spiking is going to happen to you. This experience has been a massive wake-up call.
"I would never put any drug into my body, but when it's hidden in something else, that choice is taken away from you."
Much to the bride and groom's dismay, the perpetrator fled the reception, which was delayed.
They were convinced to carry on once their guest's condition finally stabilised.
Police were called, but no officers visited the victim in hospital and the case was later dropped due to lack of evidence.
Anti-spiking campaigner Dawn Dines warned that this is part of a growing trend where drugs are being added to foods rather than just drinks.
Dawn, the CEO of Stamp Out Spiking said: "Everyone has a right to know exactly what is going into their body. There should be equal power and informed consent; anything else is spiking.
"That's why I'm petitioning the Home Secretary, Suella Braverman, to widen the legal definition of spiking and to make spiking a specific, notifiable criminal offence.
"Ms Braverman and the Home Office have until October 26 to feed back to the House of Commons Committee on the progress towards creating a separate criminal offence for spiking.
"In the meantime, I am determined that stories like this are heard."
