A special commission into crystal methamphetamine has arrived in NSW's drug-ravaged Riverina region.
Commissioner Dan Howard SC will visit Calvary Riverina Drug and Alcohol Centre in Wagga Wagga to hear about treatment programs and the impact of ice and amphetamines in the region.
He will also visit Pathways Murrumbidgee which provides drug support services before meeting with members of the local indigenous community.
The commission began in Sydney last month but Professor Howard said Wagga Wagga is among the regional communities particularly affected by ice.
"It is important that the Commission hears directly from people in our regions about the impacts of crystal methamphetamine, the availability of services and strategies to reduce harm to individuals and communities," he said in a statement on Tuesday.
The drug is more common in regional NSW than in the city and Wagga Wagga has a higher rate of use than the state's average.
The commission's visit to the region also marks the final week in which members of the public can lodge submissions to the commission.
Counsel assisting, Sally Dowling SC, opened the commission with an overview of the devastating impact the drug has had across the state.
Crystal methamphetamine in 2013 became the most prominent form of the drug and that upward trajectory has continued in recent years, she said at the time.
It is "highly addictive" and can devastate a person's social, mental and physical wellbeing, Ms Dowling said.
"Chronic use of crystal methamphetamine can cause the collapse of the user's health.
"It is sometimes associated with amphetamine-induced psychosis that, in extreme cases, may manifest in paranoia and violence and sometimes - tragically - in suicidal behaviour."
Hearings will be held between April and August in Sydney and regions including Lismore, Dubbo, Nowra, East Maitland and Broken Hill.
Submissions can be made at iceinquiry.nsw.gov.au until May 7.
Findings will be handed down by the end of the year.
