The grieving family of a teenager who died after collapsing at a music festival issued a warning about the dangers of drugs as they paid tribute to the "happy, caring and kind" young man.
Alex Herriot, from Portobello in Edinburgh, is thought to have experimented with a drug at the RockNess festival in Dores in the Highlands.
The 19-year-old collapsed in the main area on Saturday night and died in hospital a short time later. His relatives say he was not a habitual user of drugs and had been warned to steer clear of them.
They spoke of their devastation at the loss of an "immensely popular" young man, saying they would never get over his death.
In a statement issued through Northern Constabulary, the family said: "Alex, our much loved son, was happy, caring, kind, loyal and affectionate and joined in enthusiastically with any project. He was very popular with a large group of close, good friends.
"He was beautiful both on the outside and the inside where it matters most. He loved his life.
"The fact that we will not be seeing him wandering around the house with his laptop playing his music, teasing his sister and asking if there was any food and 'could he have a bus fare please' is unbearable.
"Alex was attending a music festival which he had been looking forward to enormously. As a young man who enjoyed life, it was unfortunate he chose to experiment with a drug that had such a catastrophic effect on his system.
"We are devastated that we have lost him but anything he did, in every area of his life, was done with good intent, in this case to get the most out of his festival experience."
Mr Herriot had almost completed an HND in media studies and planned to go to Edinburgh's Queen Margaret University. He was said to have enjoyed film, anime, comedy and music.
Thanking the police and the medics who tried to save his life, the family said: "The sudden death of our beloved son Alex has left his family in a state of shock and is a loss we will never get over.
"He was a very special person, always in a good mood, funny, interested in everything around him, immensely popular and loved by everyone who knew him. He had everything going for him: personality in abundance, very good, close friends, a large extended family unit that supported and adored him; and we are all devastated by our loss."
In a warning to other youngsters, they said: "Alex was not a habitual drug user. We know that young people dabble in drugs and Alex had been warned to steer clear. Please, please be aware that certain drugs can kill and please don't be the next youngster to leave their family bereft."
Mr Herriot died in the early hours of Sunday morning at Raigmore Hospital in Inverness, failing to respond to treatment.
Police said over the weekend that early indications show that he may have taken drugs.
Officers said a 19-year-old girl and a 20-year-old man were also taken to hospital from the festival in the early hours of Sunday morning. They are thought to have taken drugs, including so-called legal highs.
The force said they are making inquiries into a "legal high" substance called Benzo Fury.
