Bonnie and Lottie Ryan has opened up about the incident

The sisters explained that they had put their drinks down during a night out so they could dance with their friends.

Speaking on their podcast, Nobody Else Will Listen, the sisters said everything happened so quickly.

Both sisters said things went downhill very quickly after they took a few sips of their drinks.

They said: "We were there with our girlfriends, there were guys there as well and we went to the dance floor with our drinks. When we took our drinks back up and had a few sips, I can’t emphasize how quickly it happened."

Both of them started to feel unusual quite quickly, with the sisters saying they were unable to hold themselves up.

"We were both propping ourselves up on the walls. Our legs were going from under us. We hadn’t had much to drink. The way we were was not warranted by the alcohol alone," they said.

"My mind was okay, but my body became mush. It was really quick how badly it went downhill," they added.

What are the signs of spiking?

Spiking is becoming increasingly common, but knowing the signs and how to protect yourself is essential.

A recent study discovered that seven in 10 adults will be affected by drink spiking at some stage in their lives.

People will experience different symptoms based on what substance they have been spiked with and how much. It also depends on how much they’ve had to drink and if they’ve taken any drugs themselves.

The main symptoms will include vomiting, nausea, dizziness, feeling faint, and feeling drunker than usual.

People may also pass out and struggle to walk, speak, see, and concentrate.

Other symptoms will include memory loss or blackouts, paranoia, and hallucinations.

Some people will have a temporary loss of body sensation, which feels like having an ‘out of body’ experience.

If you have been spiked, then it is essential to get help immediately. If you think you’ve been spiked, then call emergency services for help.

Seek help from your friends or from staff and security if you’re in a bar or club.

You should also ensure you’re in a safe place and with someone you trust.
