Empty cylinders of nitrous oxide dumped on Lord Street in Southport

Giant laughing gas containers have been dumped on Lord Street this morning, reflecting a new summer trend that is worrying drug experts. 

Nitrous oxide is regularly taken by young people at parties and festivals, and the small silver canisters it is usually sold in have become a familiar sight in town centres and parks. 

Nitrous oxide is commonly referred to as "laughing gas"

The pictured cylinders were found in the so called Northern Quater close to The Grand.

The effects of nitrous oxide vary depending on how much has been inhaled but they include:

• Feelings of euphoria, relaxation and calmness.

• Dizziness, difficulty in thinking straight and fits of giggles/laughter.

• Sound distortions or even hallucinations.

• In some people, a headache can be an unwanted immediate effect.

Risks include:

• Unconsciousness or death from lack of oxygen. This occurs when the available oxygen for breathing is effectively pushed out by the nitrous oxide.
