A recent CSIRO report found regular use of vapers was likely to harm a person's health, but it suggested there were likely benefits in replacing regular cigarettes with e-cigarettes.
Brian Marlow, the campaign manager for Legalise Vaping Australia, said the report quantified points his organisation had been making for years.
"They've shown the gateway theory, that vaping leads to smoking, just doesn't exist; they've shown that vaping reduces smoking rates; they've shown that it's safer than smoking," he said.
"This is not a harmless technology, it's just significantly less harmful than tobacco and that's what we're trying to get across."
Electronic cigarettes heat liquid into vapour for users to inhale.
There are various bans across Australia that restrict the sale of e-cigarettes and liquids containing nicotine.
Many vapers purchase the products online and some don't even know that it's technically illegal.
Mr Marlow went on a road trip around Australia to speak with vapers and learn more about the human side of the technology.
"I met big burly guys that had smoked two packs a day that said they'd quit in a week," he said.
"Some of them were almost in tears talking about how it saved them."
