A 32-year-old Swiss tourist went missing during a visit to Disneyland Paris last week after taking the drug LSD.

The man, who had fallen onto the bank of a body water, was found at 12:30 a.m., after a comprehensive search by first responders and park employees.

The man was reportedly provided the drugs by his girlfriend, who was with him at the theme park. He went missing at during the day and was reported missing by his girlfriend once the park closed.

According to local news outlet L’Express, 30 firefighters, 10 divers, and 80 park employees were part of the search. The WDW News Today blog also claimed that dogs and a Gendarmerie military helicopter equipped with thermal cameras were also used.

The man and his girlfriend were detained by local police for illegal drug use.

Park representatives confirmed the incident had not affected normal park operations or disrupted guest experiences. The park’s rules state all illegal or dangerous substances, like narcotics or alcohol, that may pose a threat to visitor safety, are prohibited.

Lysergic acid diethylamide (LSD), which was first synthesized in 1938, is an illegal drug that is known to alter the senses and cause hallucinations.
