Dave Mullen was just 17 years old when he first snorted cocaine. It happened during what should have been a celebratory moment on his birthday. Offered a line of the Class A drug in a pub, he naively accepted. Completely unaware of the storm he was inviting into his life. What began as a single line shared among mates soon turned into a full-blown addiction, one that spiraled into alcohol abuse, psychosis, and a brush with death.
Now in recovery, Dave has chosen to speak out in hopes of preventing others from walking the same destructive path. His most haunting memory, a photo showing his eyes bloodshot to the point of looking possessed, has become a disturbing symbol of how quickly drug use can destroy a life.
From Weekend Use to Cocaine Addiction

After that first encounter, Dave started using cocaine more frequently, especially during social outings. Drinking with friends on soccer away days and lads holidays became the perfect setting to indulge in both alcohol and cocaine. By the time he turned 19, what had once seemed like harmless fun had taken over his life.
“I noticed it had become an addiction,” Dave explained. “Every year it got worse and worse, and would affect so many people around me due to the mental health episodes I would have.”
At his worst, Dave was consuming up to 15 pints of alcohol a day. Coupled with heavy cocaine use that sometimes extended for up to a week. He was spending thousands of pounds on drugs, completely detached from reality, both mentally and emotionally.
The Breaking Point: Devil Eyes and Psychosis After a Coke Bender

The most jarring point in Dave’s story came in August 2021. After a five-day coke bender, he suffered a severe drug-induced psychosis. A photograph from that time shows him with terrifyingly red, bloodshot eyes. A physical manifestation of the torment he was enduring internally. He was unable to see and was temporarily blind during this period.
“I was completely blind and had no vision,” Dave recalled. “Six weeks later, my eyes were still bloodshot and they remained like that for about two months.”
The haunting image led to an incident at his workplace in a retirement home, where a resident was so disturbed by Dave’s appearance that he chased him down a hallway with a Bible, convinced he was the devil.

A Relapse and a Final Wake-Up Call
Despite the trauma, Dave’s battle with addiction was far from over. The frightening experience was not enough to keep him sober. He returned to his old ways, drinking and using cocaine regularly for the next three years.
It was not until March 2024, during a hospital visit, that reality finally hit. Doctors warned him that his body was on the brink and that if he continued down this path, he could die. That moment became the turning point. Since then, Dave has remained clean and is using his voice to raise awareness about the hidden dangers of drug and alcohol abuse.
The Problem With Normalization

Dave’s story serves as a stark reminder of how easily recreational drug use can become deadly, especially in an environment where such behavior is often glamorized or downplayed. He believes society has failed to properly educate young people about the risks involved in cocaine addiction.
“We’re told the drugs are illegal but in this day and age, no one really pays attention to the law and doesn’t care if it’s illegal,” he said.
He argues that the conversation needs to shift from legalities to real, human consequences. His own story, along with disturbing images of his condition, brings a visceral reality to the discussion.
A Message of Hope and Education
Despite the chaos and near-death experiences, Dave’s message is ultimately one of redemption and education. He hopes that by speaking candidly about his struggles, others may see the early signs of addiction in themselves or someone they love.
“Cocaine goes hand-in-hand with alcohol and at a weak or naive moment, as I was when I was young, someone offered me a line and I took it,” he said. “But it’s not worth it. I don’t want cocaine to be so normalised and acceptable in society.”
Now sober and focused on his recovery, Dave is determined to help others avoid the pain he endured after his coke bender. His story is a raw, unfiltered look into the dangers of drug culture and the urgent need for better education and support systems for young people.
