It all depends how far you want to go back, but a salad bar in Wasco County, Oregon, in about 1984 is about as good a place as any. Cult leader Osho, – Bhagwan Shree Rajneesh, who is the subject of new Netflix documentary Wild Wild Country, was the leader of a sect of free-love devotees named the Sanyassin who dressed in orange robes, and lived on a ranch in the hills. Free love, chanting, crazed dancing and delusional beliefs were standard.

MDMA had been used by progressive psychiatrists for couples counselling in the US in the 70s and 80s, after the drug was resynthesised by pioneering psychedelic chemist Alexander Shulgin in the late 1960s. It escaped the shrink’s sofas to the dancefloors of the Starck nightclub in Dallas, where the drug was sold, legally, over the bar in 1984. The drug filtered from the Starck to the Osho commune after MDMA was outlawed in the US in 1984, and then moved to Ibiza with the Sanyassin, say informed insiders.

The cult members fled their commune following a 1984 bioterror attack, in which they laced salad bars in the state with salmonella in a bid to lower turnout in local elections and win more votes for their own candidates.

In a beautiful coincidence in the mid-1980s, many young men and women, especially those from deprived urban centres of Manchester and Liverpool in the gruseome Thatcher era, would travel to Europe looking to make money, watch European cup matches, and generally escape the gloom.

“Back then you could get an emergency ‘loan’ off the dole office for a cooker or a bed or some shoes or a suit for an interview,” recalls one former giro-fuelled European wanderer. “We just cashed the cheques and did one to Ibiza,” he laughs.
