There are few side effects, other than vomiting, with short-term use. [1] [2] With long-term use anemia or numbness may occur. [2] It should always be given with at least 21% oxygen. [2] It is not recommended in people with a bowel obstruction or pneumothorax. [2] Use in the early part of pregnancy is not recommended. [1]
Localized deep pain, ranging from mild to excruciating. Sometimes a dull ache, more rarely a sharp pain. Active and passive motion of the joint may aggravate the pain. The pain may be reduced by bending the joint to find a more comfortable position. If caused by altitude, pain can occur immediately or up to many hours later. Cutaneous Skin
As depth increases, so does the pressure and hence the severity of the narcosis. The effects may vary widely from individual to individual, and from day to day for the same diver. Because of the perception-altering effects of narcosis, a diver may not be aware of the symptoms, but studies have shown that impairment occurs nevertheless. [11]
When inhaled at high partial pressures (more than about 4 bar, encountered at depths below about 30 metres in scuba diving), nitrogen begins to act as an anaesthetic agent, causing nitrogen narcosis. [5] [6] However, the minimum alveolar concentration (MAC) for nitrogen is not achieved until pressures of about 20 to 30 atm (bar) are attained. [7]
In 2022 the IPCC reported that: "The human perturbation of the natural nitrogen cycle through the use of synthetic fertilizers and manure, as well as nitrogen deposition resulting from land-based agriculture and fossil fuel burning has been the largest driver of the increase in atmospheric N2O of 31.0 ± 0.5 ppb (10%) between 1980 and 2019."

Shawn Johnson East decided against using “narcotic” pain medication during her C-section delivery based on her history with Adderall. “Long story short, during my comeback in 2010, I was ...
Nitrogen narcosis is also called “L’ivresse des grandes profondeurs” or "rapture of the deep". Nitrogen constitutes 78% of dry air, but at surface pressures it has no sedating effect. At greater depths, however, nitrogen affects the brain in the same way as nitrous oxide (also known as laughing gas ) and other anaesthetic gases.
Fentanyl patches are indicated only for patients with moderate to severe chronic pain who have been taking regular narcotic pain medication for more than a week and who are considered opioid-tolerant. Overdose can occur when patients use more patches than prescribed, change the patches too frequently, or expose the patches to extreme heat. [7]
