I am trying to keep people to time because there are a lot of people to bring in and we are under pressure of time. I call Senator Costello.

I was taken by what Senator Ruane said. It is not often I have heard her compliment herself but everybody in Tallaght is so proud of her. She has achieved so much and she has huge respect in Tallaght.

I also want to comment on what Senator Andrews said. I think people are bored of the whole "Government let you down" thing. A lot of my constituents, when they get that response from Sinn Féin, just come to me to get stuff sorted out. It is boring now at this point. I am going to buy the Senator a present. It is a book called The Secret. It is about positive thinking and all that. It is really good for the health.

Today, I raise the growing problem of the misuse of nitrous oxide and the serious impact it is having in my community. I am not the first to raise this and I will not be the last but I am constantly receiving reports - one as recently as this morning - about the huge number of dumped nitrous oxide canisters in the community. If there is a car park that does not have a gate on it is left full of these. I have had to clear up car parks with people. It is not just an environmental issue. It is clear to see from the huge quantities of these canisters that recreational use is becoming more widespread in public places. What concerns me most is not the litter, because litter can be fixed; it is the health implications that cannot be undone. A recent study by the RCSI in Beaumont Hospital found a significant increase in cases of young people suffering spinal cord damage linked to nitrous oxide use. The neurological issues can be helped but nobody is making a full recovery on this and that is really concerning. It is also a huge issue with road safety. People are going around with balloons hanging off their lips. I want to know what powers An Garda Síochána has to deal with this. If members of the Garda see someone who is found driving while under the influence of nitrous oxide or are consuming it behind the wheel, are there sufficient drug driving laws or are there gaps that need to be addressed? The Minister will have to come in on this because it is a public health issue, an environmental issue but also a road safety issue.
