Urgent warning after student, 24, died from inhaling three big bottles of laughing gas every day

NITROUS oxide - also known as laughing gas or hippy crack - was recently made a Class C due to the dangers associated with the drug.

It can cause a range of health issues and in some cases can even be fatal.

Some common side effects from inhaling the gas are dizzinessnausea, disorientation, loss of balance and weakness in legs, according to a study on its risks published to the National Library of Medicine.

Nitrous oxide can impair memory and thinking, the research mentioned. Some users might also feel anxious or paranoid.

According to the Alcohol and Drug Foundation (ADF), the gas from nitrous oxide bulbs is intensely cold, sometimes as low as minus 40 degrees Celsius.

Inhaling directly from the canister or crackers - handheld devices used to 'crack' open canister - can cause frostbite on the nose, lips and throat, even the vocal cords.

The icy chill of the gas canisters can also cause cold burns to the hands.

Long term, heavy use of laughing gas can cause a lack of vitamin B12. Severe deficiency can lead to serious nerve damage, causing tingling and numbness in the fingers and toes.

Lack of B12 can also cause damage to the spinal cord.

In some cases, frequent and prolonged use of nitrous oxide has been linked to thromboembolic events - this means a blood clot has gotten stuck and caused an obstruction.

The so-called laughing gas has also resulted in deaths.
