A teenager from Melbourne nearly got killed after drinking a single shot of free whisky offered while having a tubing trip in Laos.

The 19-year-old Annika Morris, name of the victim, was sent to the hospital after her heartbeat went unstable according to Jeff Morris, her father.

Melba Blyth-Elvin, Annika's friend who was traveling with her, was believed to be Annika's savior when the incident took place on Monday. Mr. Morris said if not with Melba, something worst could have happened.

Mr. Morris said her daughter's friend sent Annika to the hospital immediately when his daughter started losing her sight and hearing.

If Melba wasn't there his daughter could have died. Annika could have fallen into the river and got killed.

Annika is allergic to penicillin, so when the local doctors attempted to administer such a medicine, a German doctor fortunately interfered. Otherwise, her condition could have gotten worse.

The doctor discovered methamphetamines in Annika's system causing the enlargement of the pupils.

Mr. Morris believed that it was the free whisky that had caused her daughter to be in this situation.

This year, three Australians were found dead in Laos. The most recent was the 22-year-old Alexander Lee, whose body was discovered lifeless next to his girlfriend in a room at Luang Prabang hotel.

The other two were Daniel Eimutis and Lee Hudswell, who died in January while having a tubing trip in Vang Vieng.

Annika and her friend flew back to Melbourne and arrived today stressed and upset over what had happened.

Laos appeared to be a dangerous site for Australian travelers during the latest months considering the number of deaths found in the South-East Asian nation.
