Dyfed-Powys Police admits drugs are "an issue" in Llanelli, and says tackling drug misuse and supply is "a priority" for the force.
Like other towns and cities in the UK drugs are an issue the police in Llanelli face.
Tackling drug misuse and supply is a priority for Dyfed Powys Police, and we act proactively to disrupt the supply of drugs into our communities in order to reduce harm and bring the dealers/suppliers to justice.
We will work closely with the producers of the programme to investigate this incident.
We conduct targeted work focusing on the harm caused by drugs through successful operations where drugs are seized and individuals arrested.
The public can also help us in our fight against drugs by providing us with information relating to drug misuse or supply within our communities – call the police on 101 or anonymously by calling the independent charity Crimestoppers on 0800 555111.
The Health Minister will launch a campaign later today to highlight the dangers of using the banned substance mephedrone. Commonly called 'meow meow' or 'miaow miaow', it is estimated that three-hundred thousand young people in the UK used the drug last year.
The dramatic rise in the use of mephedrone is concerning given the serious mental and physical harm the drug can cause both in the short and long term.
As a class B drug mephedrone carries a penalty of up to 5 years for possession and 14 years for supply. One of the aims of our campaign is to educate people about the dangers of the drug and the damage it can cause.
