The parents of Henry Miller, who died after taking a hallucinogenic drug during a tribal ceremony in South America, have released a statement about the incident.
David and Elizabeth Miller said: "In the last 48 hours we received the exceptionally sad news that our son Henry has died whilst travelling in Colombia.
"We understand that he took part in a local tribal ritual recommended by the hostel that he was staying at. The ritual involves a drink made from local plant infusions.
"We are awaiting further information from the Foreign Office, but it is likely that a reaction to this drink was the cause."
Mr Miller was in South America on a gap-year trip. His family described him as "an adventurous person who travelled extensively".
