Colombian authorities kicked Steven Semmens, 35, back to Swansea after a video of him taking the class A drug made the TV news and triggered uproar across the South American nation.
Mr Semmens was hit with a five-year ban from entering Colombia, where his wife and children still live. He is unable to bring his family to the UK because of visa restrictions.
The Swansea local travelled to Colombia late last year after meeting a woman in Ibiza. He claims his problems began when he foolishly agreed to a friend’s flippant dare.
“My mate asked me to do a line off Escobar’s grave and it just went mad. It was funny at the time but I’m ashamed. Everybody said I was a disgrace and I was making the country look bad,” Mr Semmens told The Mirror.
“The president even mentioned me on TV and the police were ¬worried for my safety. It was really scary. I regret doing it so much. People sent me death threats on Facebook.
“They said if they found me they would skin me alive. I can’t see my children and that hurts.”
Mr Semmens said he had no idea how lining up cocaine on Escobar’s tombstone and snorting it with a rolled up bank note would bring about such heavy consequences. Despite being one of the world’s most wanted men, Escobar was revered as something of a Robin Hood figure by many of Colombia’s poorest.
“I was in a bar in Medellin when the news flashed up on the TV of me doing the cocaine. All the locals were going crazy so I joined in slagging off the guy on TV because I didn’t want them to know it was me,” he told The Mirror.
“I went home, shaved to change my appearance and went to the mountains outside Medellin to hide. As soon as I could I went to Cartegena and hid.
“Then I went to the capital, Bogota, but the police found me.”
In April, Mr Semmens was banned for five years from entering Colombia, forcing him to live most of 2018 apart from his wife and twins.
At his peak, while in charge of the notorious Medellin drug cartel, Escobar was believed to be one of the 10 richest people in the world.
DEA officials believe Escobar was trafficking a massive 80 percent of the cocaine smuggled into the US before he was shot dead by police in 1993.
His most famous mansion was Hacienda Nápoles, located on a sprawling 247-acre estate in Puerto Triunfo in Colombia.
There the drug king pin built a zoo with hippos, giraffes, elephants and other exotic animals.
Mounted on top of two poles at the entrance gate to Hacienda Nápoles sits a replica of a Piper light aircraft, which transported Escobar’s very first shipment of cocaine to America.
United Nations data show Colombia is now producing more cocaine than ever.
In 2016 it was estimated the jungle laboratories produced 866 tonnes; the year before it was 649 tonnes.
Cocaine production hit record levels in 2017, rising to 1400 tonnes.
