Research by ITV News shows incidents of violent crime have gone down in Wales a decade since the introduction of 24 hour licencing.
It was feared allowing people to drink for longer could increase rates of violence.
People are drinking more responsibly according to a report analysing South Wales Police's campaign to tackle drunken violent crimeRead the full story ›
Experts at Cardiff University say cheap alcohol in supermarkets is fuelling violence, and making booze more affordable now the economic downturn is over would be a mistake.
Figures from the Violence Research Group show the number of people injured in serious violence dropped by 10% in 2014 compared to 2013.
But researchers said that more than 200,000 people going to emergency departments in England and Wales every year because of alcohol is "still far too many".
As in other years, the bulk of the violence still being committed involves males between the ages of 18 and 30, mainly taking place in urban streets at night.
Researchers attributed the reduction to a combination of factors including an increase in CCTV leading to police intervening in fights more quickly; better sharing of anonomised data between A&E departments; police and local government; and people drinking less due to alcohol being more expensive and having less disposable income.
The Welsh Government says 34,000 hospital admissions caused by alcohol misuse every year cost the Welsh NHS £109m annually.
Deputy Minister Health Minister Vaughan Gething says figures show more then 4 out of 10 adults in Wales report drinking more than the recommended guideline amount of alcohol at least once in the last week.
Statistics released last month for alcohol-related deaths showed there were 467 deaths in Wales in 2013.
The Welsh Government says it will invest almost £50m in 2015-16 in initiatives to tackle the harms associated with both alcohol and drug misuse.
"Alcohol misuse is leading to a range of well-evidenced health and social harms, particularly for the significant minority of people who drink to excess and do not recognise the harm they are doing to themselves and others.
While there has been an overall downward decline in the number of alcohol-related deaths in Wales since 2008, that people die as a result of consuming too much alcohol is still a stark reminder of the challenges we still face in tackling the causes and impact of substance misuse."
A Welsh health board has issued a plea for people to drink responsibly after a surge in alcohol-related injuries on Halloween.
Abertawe Bro Morgannwg University Health Board said the A&E department of Morriston Hospital "was filled with witches, mummies, ghosts and other revellers in fancy dress".
It said patients were either sleeping off the effects of too much alcohol, or being treated for alcohol-related injuries - including from fighting.
Chief Executive Paul Roberts said he was "dismayed" to see some pubs and clubs offering cut-price drinks - some as cheap as 10p - on the night of October 31st.
He slammed the move as "irresponsible" and said people who drink alcohol to excess - and those who make it available - should consider the impact of their actions.
Parents in Wales are over-estimating the number of young people who drink alcohol.
According to new figures, from the Alcohol Education Trust, less than a quarter of 11 to 15 year olds think its okay to get drunk.
But parents here thought the figure was much higher.
Official figures show there's currently a downward trend in the number of young people trying and drinking alcohol
Wales has come a step closer to seeing the introduction of minimum prices for alcohol. An expert group has told the Welsh Government that the move would 'reduce harm.' But the industry remains to be convinced. Our Political Editor Adrian Masters reports.
The Welsh Conservatives are supporting moves to introduce minimum alcohol pricing in Wales. That's despite a controversial decision last year by David Cameron to drop a similar plan for England. The Prime Minister feared it would be 'unworkable' and open to legal challenge.
But the party's Shadow Health Minister in the Assembly, Darren Millar, says it can work in Wales.
Health Minister Mark Drakeford has welcomed today's expert report on minimum alcohol pricing which he says adds to the evidence that the move would help cut problem drinking.
And he says it won't have any impact on social drinkers.
Most people whose budgets are tight are sensible drinkers, the drink they buy will already be above the 50p minimum price per unit we propose. The evidence in today's report is that this will not have an impact on people who are living in pretty modest circumstances. It will help us to target people whose drinking has gone beyond that."

The price of a drink could go up in Wales if the Welsh Government takes the advice of experts and put a minimum of 50p a unit on a drink.
Plans to introduce a minimum price for alcohol have been backed by a panel advising ministers on substance misuse.
Experts said the measure would protect vulnerable people, boost public health and improve community life. It could become law in 2015.
