Brazil was one of the first countries in the world to ban Electronic Smoking Devices (ESDs). This ban was motivated by the lack of evidence regarding the alleged therapeutic properties and harmlessness of these products. Anvisa was criticized for this move, especially by electronic cigarette's users groups. These groups argue that prohibition prevented people's access to a product that would aid smoking cessation and be less toxic than ordinary cigarettes. Thus, the question arises as to whether this decision was successful. Available data show that ESDs have diverse formulations and some toxic substances are released at significant levels during use. Studies in animals and humans have shown a potential toxic effect, also affecting the health of passive smokers. Studies are still inconclusive regarding its use as a cessation tool. A high level of use among adolescents was observed in countries whose use was authorized. Thus, Brazil's ban prevented the population from consuming a product that has not been proven effective toward smoking cessation, with indications of significant toxicity and highly attractive to young people.
