A HSE helpline has received more than 3,100 calls about possible drug-poisoning this year.
The National Poisons Information Centre helps the medical profession and the public manage acute-poisoning.
Details released under the Freedom of Information Act show it has received 5,500 calls about suspected human-poisoning this year.
While more than half relate to drugs, Dublin city GP Austin O'Carroll says many cases aren't about illegal substances.
But he does think there's a huge problem in this area.
