„Balloon“ with consequences: The truth about nitrous oxide
In recent years, Bulgaria has seen a disturbing trend. Laughing gas, also known as nitrous oxide (N₂O), has gained popularity among young people, especially in nightclubs and discotheques. It is often inhaled from balloons sold by street vendors or directly on the premises of establishments. While its use may seem harmless and short-lived, medical and scientific research, as well as real-world cases, demonstrate the serious risks that this „fun“ gas carries. In this article, we summarize what the substance is, what dangers it hides, and why we need to be particularly careful.
What is laughing gas?
Nitrous oxide is a colorless, sweetish gas that is used in medicine as a short-term anesthetic. It is also legally used in the food industry, for example, in cream chargers. When inhaled, it causes short-lived euphoria, laughter, dizziness, and altered perception – hence the name „laughing gas.“ But this pleasure only lasts a few minutes, and the harm can be serious and long-lasting.
Use in medicine – from benefit to abuse
Nitrous oxide has a long history in medicine as an inhalation anesthetic with a rapid effect. It is used for short surgical procedures, in dentistry, and in maternity wards for pain relief. In a controlled hospital setting, the gas is safe.
The problem arises when uncontrolled, recreational use, when inhaled in large quantities, without medical supervision. It is precisely in these cases that the most serious health risks arise.
What are the potential risks and harms?
-
Nervous system disorder
Nitrous oxide blocks the action of vitamin B12, which is vital for normal nerve function. A deficiency can lead to:
- Tingling and numbness in the extremities;
- Muscle weakness and unsteady gait.;
- Impaired sensitivity;
- Memory and concentration problems;
- In severe cases – permanent spinal cord injury.
-
Oxygen deficit (hypoxia)
When inhaled, nitrous oxide displaces oxygen in the lungs. This can lead to:
- Loss of balance, dizziness;
- Seizure;
- Brain damage or suffocation in severe cases.
-
Cardiological risks
It can cause:
- High blood pressure;
- Heart rhythm disturbances;
- Increased risk in people with heart disease.
-
Bone marrow suppression
Prolonged use may lead to:
- Anemia;
- Weakened immune system;
- Chronic fatigue.
-
Physical injuries
Inhaling directly from vials or capsules can cause:
- Frostbite and burns to the lips and throat;
- Mechanical injuries;
- Lung damage.
-
Psychological dependence
Although it does not lead to physical addiction, nitrous oxide creates a rapid behavioral dependence – the user seeks the sensation again and again, underestimating the risk.
The use of nitrous oxide in Bulgaria is a serious public health problem, especially among young people.
Usage statistics:
- Students: Studies show that more than 40% of students in Bulgaria have used laughing gas at least once.
- Students: Approximately 25% of high school students (grades 8–12) have tried "laughing gas" at least once.
- 15–16 year oldsBulgaria ranks first among 37 countries in nitrous oxide use by 15 and 16-year-olds.
In 2022, Bulgaria implemented a ban on the sale of nitrous oxide to individuals under 18 years of age. However, the substance remains available in many establishments and online platforms.
Real cases from the practice of „Medical Karadji“
As coordinators at Medical Karaj, we are increasingly encountering severe consequences from the use of nitrous oxide. One of the most recent cases we consulted on is the following:
- 22-year-old man regular use of nitrous oxide develops Polyneuropathy due to vitamin B12 deficiency. With him, this leads to Difficulty walking и Dragging right leg. Despite the restored vitamin B12 levels at this stage, the complaints have been going on for almost a year. The prognosis is uncertain and requires long-term rehabilitation. It is possible that the damage may be permanent.

Conclusion
Laughing gas is not harmless. Used outside of medical conditions, it leads to real and proven health disasters. In just a few minutes of „fun,“ a person can face months or years of pain, rehabilitation, and inability to fully recover.
Awareness, particularly among young people, is of key importance. Stricter regulation of sales is also needed, as well as a stronger presence of the topic in schools, media, and the healthcare system. Awareness, conversations, and a clear line between „fun“ and „risky behavior“ are crucial – for us and for our children.
