The Australian Medical Association (AMA) has raised concerns young people are continuing to access vaping products despite an import ban coming into effect.
From the start of October, the Australian Border Force has had the power to intercept packages of nicotine e-cigarettes, nicotine pods or liquid nicotine.
The Therapeutic Goods Administration (TGA) said the decision to prohibit imports was because of a "significant increase" in their use by children as young as 11 who were "illegally" being sold them.
But the AMA's SA president Michelle Atchison said she was concerned young people were continuing to access disposable vaping products at convenience stores and other retailers.
"There have been some recent regulations so that we're controlling the importation of nicotine," Dr Atchison told ABC Radio Adelaide.
"These disposable vaping products — they're a real issue for the AMA because they're getting around what we're trying to do."
It is estimated that more than 200,000 Australians use e-cigarettes.
According to a recent study of 65 common liquids used in vaping products, many contain carcinogenic and other harmful ingredients.
It is the most comprehensive study of products available in Australia to date and researchers found evidence of a group of chemicals called polycyclic aromatic hydrocarbons (PAHs), which has been linked to lung, bladder and gastrointestinal cancers.
Dr Atchison said while access to vaping products has been restricted, they remain legally available through doctors, who can prescribe them to help people quit smoking.
But she said evidence — including from under her own roof — suggested they were addictive in their own right.
"I have a young adult in my house who uses these," she said.
"She had been smoking cigarettes so, for us, it wasn't a bad thing she had started vaping because it smelt less disgusting than cigarettes, but it's been very difficult for her to come off of them.
"It's scary that our young people are out there looking for these products. They're easy to find. They get around having to go to a GP and get a prescription."
South Australian Secondary Principals' Association president Peter Mader said anecdotal reports from the eastern states suggested vaping was alarmingly popular among schoolchildren.
"It's reached a tipping point there where there's more vaping going on in schools than there is the traditional smoking which has always been a problem," he said.
"Here I don't think it's quite that prevalent yet, but clearly it's coming."
