The 32-year-old man had been handing out leaflets in his home town of Villeurbanne, in Lyon, reported Le Progrès newspaper.
On the handwritten leaflet, the dealer noted that he would even offer home delivery for orders over €100. He added his first name and a phone number, together with a taped half gram of cannabis resin.
Considering his contact details were on the leaflet, one can only imagine that local police didn't have too much trouble tracking down the man after one of the leaflets was passed on to officers.
When raiding the home of the man, who is unemployed, they found over 100 grams of cannabis.
"We stop hashish sellers regularly," Noël Fayet, a superintendent for police in Villeurbanne told Europe1.
"But this is the first time we found someone making little leaflets with a little bit of free cannabis. It's a very special method of marketing indeed."
The suspect, who will appear in court soon, reportedly told police that he wasn't selling the drugs, rather using the leaflets to find people with whom to enjoy the cannabis.
Earlier this year dealers in Marseille made headlines the world over when it was revealed they were handing out loyalty cards to their regular customers.
When buying cannabis from dealers in the southern French city, customers were given a reward card including the product price list, opening hours (11am to midnight), and a message that says "We look forward to seeing you in the neighbourhood, thanks for your loyalty".
