An electronic cigarette containing cannabis will be available to buy in Britain from Christmas Day onwards.
KanaVape uses hemp with five per cent cannabidiol (CBD), meaning it apparently provides a relaxed feeling but without the psychotic side-effects.
The makers of the first e-joint, which graced the market oversees in June, Antonin Cohen and Sebastien Beguerie, claim their product is entirely legal as it does not contain chemical THC.
Users can inhale cannabis vapour without the usual smell of smoke.
Drug charities have suggested the product will indeed be legal under British law due to its lack of THC.
Speaking to Metro.co.uk, Sophie Macken, at the Independent Scientific Committee on Drugs, said: "CBD is legal and has some therapeutic and neuroprotective properties.
"It is not usually something that would be used recreationally though so this sounds like a bit of a gimmick."
The hemp used in the e-joint is grown in France, Czech Republic and Spain without the use of synthetic pesticides and chemicals.
The cannabis e-cigarette will also go on sale in France, where it is legal, but the health minster immediately moved to ban the product.
KanaVape makers Antonin and Sebastien said: "We made KanaVape to give millions of people a legal and tasteful way of using cannabinoids. We craft our production with love, care and scientific research.
"KanaVape is good for our customers and good for the planet."
