THE article headlined “Police warning over laughing gas” (Echo, June 26) confirmed my suspicions that the silver and some grey coloured canisters I have being finding over the past few weeks are nitrous oxide containers.

The disturbing thing is they were not found in a public park but on an industrial estate – the majority found in a car park outside the perimeter fence of a British Gas Pumping Station (no pun intended) and the adjacent road, which means whoever’s inhaling this gas is driving there and leaving by the same means.

In your article, Sergeant Heidi Lewis makes no reference to the effects this gas would have on anyone driving.

But I can well imagine the danger this could pose to other road users and the general public.
