Consumers are also concerned that authorities could extort them because while it is not illegal to possess vapes, the new law is unclear about the number of devices that can still be considered as personal use.
"If I make a vague law ... I give corrupt authorities the ability to interpret it in a way to extort people," said Juan José Cirión Lee, a lawyer and president of the collective Mexico and the World Vaping. He plans to challenge the new regulations in court, saying they are ambiguous and full of contradictions.
While Mexico's ban was being forged, organized crime expanded its share of the sector across northern states and the country's largest cities, Guadalajara and Mexico City. Sometimes, they even marked their product with stickers or stamps to distinguish their brand, reminiscent of their stamped fentanyl pills.
Rosario, the lawyer, talked of intimidation, extortion and violence that forced sellers in states like Sonora to get out of the business. Others, like some of his former clients in Sinaloa, decided to sell vapes supplied by the cartel, which promised they would have no problems with authorities, he said.
"I have lost about 40% of my clients," Rosario said.
