Dozens of deaths linked to vaping could just be ‘the tip of the iceberg,’ a damning report has warned.
Scientists from the University of Texas have claimed the e-cigarettes inflict more damage to the lungs than previously feared.
X-rays of a 24-year-old vaper who had been smoking the devices daily lay bare alarming abnormalities, caused by fats from vaping oils found in his lungs.
For a week before the scan, the patient had been suffering shortness of breath, a cough, chest pain and fever.

He had a past history of asthma, adding to concerns e-cigarattes may be particularly dangerous for those with the breathing disorder.
Up to last week, 1,604 cases of lung injury associated with vaping had been reported across the US – with 34 resulting in death.
But these numbers likely underestimate the true incidence and prevalence of disease due to lack of recognition of e-cigs’ connection to disease.
The study, published in the journal Radiology: Cardiothoracic Imaging, is ominously titled ‘Electronic Cigarette or Vaping-associated Lung Injury (EVALI): The Tip of the Iceberg.’
Co-author Dr Suhny Abbara, of the University of Texas (UT), said: ‘Radiologists will continue to play an important role in recognising this emerging entity.
A total of 34 deaths from vaping-related illness have been reported in 24 US states (red) in the US. Every state but Alaska has confirmed at least one of the 1,604 cases of lung damage

‘We encourage the medical imaging community to produce scientific evidence and medical knowledge to help advance our collective understanding of the effects of e-cigarette use on the lungs and other organ systems.’
The unnamed patient had been regularly using e-cigs – as well as tobacco and marijuana.
He had a high blood count, indicating disease. A dye injected into his blood vessels showed up large patches of white in his lungs.
Healthy organs would be dark, indicating they are clear. Tissue samples suggested he had the respiratory illness lipoid pneumonia: a potentially serious disease caused by inflammation of the lungs.
Doctors believe it was triggered by vaping. The man was prescribed steroids.
Dr Abbara, who is also editor of the journal, said: ‘The diagnosis of lung injury due to vaping should be a differential possibility in patients presenting with lung abnormalities on radiographs or chest CT images and exposure to e-cigarette products within 90 days of the presentation.’
Dr Abbara and co author Dr Fernando Kay, of the department of radiology at UT Southwestern Medical Centre, aim to raise awareness on how to identify lung illnesses caused by vaping.
They said research should be approached as a team effort by members of multiple specialties including pathologists, epidemiologists, pulmonologists and emergency physicians.
Dr Abbara added: ‘It is crucial that radiologists drive some of the initiatives to better understand the mechanisms of disease presentation, facilitating the diagnosis and management of these patients.’
The first case was reported at the end of March but authorities have still not identified the chemicals that are causing the illness. It also remains unclear if all cases are the same kind of injury.
The outbreak does not appear to be linked to long-term use of nicotine e-cigs, which have been used in the US for over ten years.
Officials instead believe illicit products containing THC – the psychoactive component of cannabis – are to blame.
Public Health England (PHE) has said it is possible similar items are being sold in the UK, and stressed users should buy from reputable sources.
Studies have shown vaping can cause similar damage to that seen in smokers of traditional cigarettes – and people with chronic lung disease.
Earlier this week PHE said it is ‘as certain as ever’ that vaping is less harmful than smoking.
