'Every family affected by addition'
The new Junior Minister with responsibility for Public Health and Drugs Strategy has said "every family has been affected some way or another as a result of addiction".
Speaking on RTÉ's Drivetime, Colm Burke said "drugs are freely available" in Ireland, adding it is a cross -departmental issue.
He acknowledged that policing the waters to stop smuggling is "a challenge", but added the gardaí had made substantial seizures.
"It's not only about making sure drugs aren't coming in, but also about education and prevention because no matter what you do in relation to trying to prevent drugs being imported, people are going to get access to them," he said.
Mr Burke said "a lot of work" had already been done "getting the message out there about the dangers of even experimenting with drugs".
The minister said he had been told of people "who ended up in psychiatric units" because drugs "have triggered other health problems".
Mr Burke said he not received a "full briefing" yet on the Citizens' Assembly on drugs due to "only being in the position within the last few hours".
"I've a lot of work to do in relation to familiarising myself with all of the issues that the department is facing," he said.
He said that he "would certainly recommend" that the recommendations that outlined by the Citizens' Assembly on Drugs "would be dealt with in the earliest possible date".
