Fitness instructor used to smoke up to 20 joints a day
This is the personal fitness trainer who used to smoke up to 20 cannabis joints a day.
The case of Keith Devoy (27) revealed how a man with 79 previous convictions and a history of heavy drug use was living "a wholly unproductive life", sitting around taking drugs with his friends.
However, in a dramatic transformation in lifestyle, he has gone from damaging his body with drugs to pursuing a career in helping people stay fit and healthy.
Devoy, from St Ronan's Park, in Clondalkin, claimed the birth of his 10-month-old daughter completely changed his life.
The transformation has been described as admirable, though one health expert has warned about the dangers of becoming involved in fitness after heavy drug use.
Renowned fitness coach Pat Henry told the Herald anyone getting involved in training and fitness after heavy drug use should first contact a doctor.
The main concern was the effect that long-term and heavy drug use can have on the body.
"Anyone who is coming off such heavy dope should see a doctor. Training will increase the heart rate and the metabolism.
"It can put a lot of strain on the heart and the problem is, sometimes it can't take the strain," said Mr Henry, who has been at the forefront of fitness in Ireland.
Speaking generally about undertaking fitness regimes and using drugs, Mr Henry said: "I wouldn't train someone using that amount of dope. It's just too dangerous.
"There's no way they could keep their mind on what they were doing."
Mr Henry has worked with a wide range of well-known personalities and musicians, including David Bowie, Bruce Springsteen, Dolores O'Riordan and Def Leppard.
He also congratulated the former drug user for turning his life around.
Devoy was ordered to complete 100 hours community service in lieu of three months in prison.
He admitted at Blanchardstown District Court to possession of cannabis and cocaine, as well as having cannabis for sale or supply.
During the case the investigating officer, Garda Marcella Shanahan, spoke about how she obtained a warrant and searched his home on January 8, 2015.
During the search, Gda Shanahan found cocaine worth €49 and cannabis worth €1,421 in the defendant's bedroom.
Devoy admitted the cocaine was for his personal use while he said he bought the cannabis in bulk and planned to share it with his friends.
The court heard Devoy's 79 previous convictions were mostly for road traffic matters.
His defence counsel said that Devoy began using drugs after his father died in a road accident in 2006, and he soon had a problem with cannabis and cocaine.
However, the court heard that he had successfully turned his life around in the last year, and that his mother was in court to support him.
To mark his transformation, it was stressed in court that Devoy was now a qualified personal trainer. The incident in which he was caught with drugs was described as a serious "wake-up call" for Devoy.
He is now clean of drugs, and is focused on caring for his daughter, along with his move into the fitness industry.
The judge in the case ordered a community services report to see if Devoy is suitable to complete 100 hours community service in lieu of three months in prison.
The judge adjourned the matter to May when it is expected to be finalised.
Devoy hadn't been in trouble for drugs-related matters in six years.
