An ITV Cymru Wales reporter has been undercover to reveal the extent of the drugs problem on the streets of Llanelli.
After spending less than an hour in the West Wales town, our reporter had managed to obtain a gram of the class B drug Mephedrone.

Police are investigating whether his death is linked to what they believe is a form of ecstasy called "Green Apples."
DCI Andrew Williams he is "absolutely desperate to ensure that nobody else loses their life as a result of taking these tablets."
Anyone with information about people who use or supply "Green Apples" or any other controlled drug is asked to contact North Wales Police on 101, or Crimestoppers on 0800 555 111.
A drug charity has told ITV Cymru Wales that one of their biggest battles is fighting against new and unknown drugs.
The message comes after the death of 19-year-old Thomas Jones from Llangefni after he was thought to have taken a drug with the street name "Green Apples" - believed to be a form of ecstasy.
Endaf Evans from charity CAIS says that experts are fighting often against new and unknown substances.

Officers have warned people about the dangers of "Green Apples", after a 19-year-old from Bangor was in intensive care, also believed to have taken the particular form of ecstasy.
North Wales Police and Betsi Cadwaladr University Health Board are warning people about the danger of a form of ecstasy called "Green Apples", after the death and serious illness of two local men.
A 19-year-old man from Llangefni died on Saturday after suspected drug use.
Two weeks ago, a 19-year-old man from Bangor was admitted to intensive care after he had taken controlled drugs, but he survived.
From our initial enquiries there appears to be a link in that we understand both young men took the drug ‘Green Apples’ which information suggests is a form of MDMA (Ecstasy), albeit work is ongoing to confirm this.
At this time I would strongly urge those who supply or use ‘Green Apples’ in particular to think hard about what they are doing and to stop immediately.

The rate of deaths from avoidable causes remains higher in Wales than in England, although it has fallen by almost a quarter over the 10 years.
