TAVISTOCK Police have shared a warning following an increase in used nitrous oxide canisters scattered around the town.

Nitrous oxide, otherwise known as ‘laughing gas’ or ‘hippy crack’, is used for a cheap and quick high, which works by starving the brain of oxygen.

The use of nitrous oxide can cause instantaneous death through cardiac arrest or other life threatening conditions.

Fainting, dizziness and a decrease in mental performance are some of the minor side effects associated with the use.

In addition, drug use from a canister is uncontrolled and unmeasured so the risks are higher.

A spokesperson for Tavistock Police said: ‘If you know someone who uses nitrous oxide or any other drug refer them to drug advice organisation FRANK.

Alternatively, please contact us with any information you may have on the 101 number.’
