Speaking ahead of the conference, which will be held in the Tower Hotel as part of Legal High Awareness Week, Ms Anderson said;
“The dangers of legal highs are well known and unfortunately there are families who have lost loved ones as a result of these substances.
“Many others, particularly young people, have also been severely damaged by taking legal highs.
“And the problem is these substances continue to be sold legally over the counter.
“I am glad to see that this awareness week includes events in Derry and Donegal because the devastating impact of legal highs is the same everywhere.
“That is why we need an all-Ireland approach to dealing with legal highs.
“Currently, once a substance is banned in the North it can go back on the market if a single ingredient is changed. In the South a new license must be obtained before a product can be sold.
“Effective legislation is needed right across the island to protect people from these potentially deadly substances.
“I have been raising the dangers of legal highs in the European Parliament and will continue to have these products banned.” ENDS/CRÍOCH
