With the great controversy that electronic cigarettes caused after its consumption boom world , even to the Brazil (even if still not being legally allowed ) , is the first time a scientific research demonstrates the safety and effectiveness of electronic cigarettes for smokers who want to reduce , but not stop smoking . The study, which presents the Doutíssima Brazil , evaluated the volunteers for a whole year . Check out .
A more than justified , given the problem of smoking
The research is warranted before health problems caused by tobacco and the results remain rather modest about the effectiveness of currently accepted methods to stop smoking . Besides the controversy caused around the electronic cigarette ( also known as e -cigarette ) since he became popular and gained acceptance among smokers seeking an alternative less harmful .
The WHO ( World Health Organization ) also has a negative acknowledgment about the electronic cigarette and it can not be marketed in Brazil . There is still a huge lack of research and studies like this that can prove the efficiency and to ensure the safe use of these products . In fact , many brands are manufactured in China, where quality control on these products is still doubtful . Thus, a detailed study of the electronic cigarettes is more than necessary .
The research : step- by-step
During the study examined 300 people of 18 to 70 years , in good general health and smoking for at least 5 years of a minimum of 10 cigarettes per day . No method of psychological support was proposed . The volunteers were informed that during the entire investigation , they could smoke as many cigarettes normal or electronics they wanted , in order to represent the " real life " of the smoker .
Participants were randomly assigned to 3 groups of 100 people and totally blind . Neither the researchers nor the volunteers knew which group people were classified . The groups were :
- Group 1 : electronic cigarettes with 7.2 mg of nicotine
- Group 2 : 7.2 mg electronic cigarettes with nicotine and after 6 weeks with 5.4 mg of nicotine
- GROUP 3 : electronic cigarettes without nicotine
Each patient received a sufficient amount of electronic cigarettes during 12 weeks ( intervention phase , with a maximum of 4 packets a day) had a follow-up after 54 weeks of quantities ( observation phase ) . During this period , the volunteers completed a diary and received nine requests for verification of control : number of cigarettes smoked per day ( electronic or normal) , level of exhaled carbon monoxide , withdrawal symptoms (anxiety , depression , insomnia, irritability , constipation , amount of food eaten ) and minor side effects (blood pressure , heart rate , weight , cough , dry mouth , throat irritation , difficulty breathing , headache ) . Electronic cigarettes used contained propylene glycol and vegetable glycerine flavored ( with or without nicotine ) .
Results surprised the researchers after 1 year of analysis
After one year of follow up , 65 (group 1 ) , 63 (group 2 ) and 55 (group 3 ) files were analyzed and the results were similar in the 3 groups of volunteers who had no intention of quitting :
- 8.7% had stopped smoking completely during this year. Number that is quite large and has impressed researchers .
- 10.3% of the volunteers had a significant reduction in the rate of exhaled carbon monoxide and the number of cigarettes smoked per day .
Almost no side effects or withdrawal symptoms were recorded . Participants had a good acceptance and overall perception of electronic cigarettes .
The conclusion of the research is that the electronic cigarette is a very useful means for smokers who want to reduce their amount of tobacco consumed per day . More studies are still needed for people who want to quit completely with addiction , but the rate of withdrawal from the study are encouraging .
Even though the effects of electronic cigarettes in the long term are unknown , studies like this are important for the advancement of anti-smoking techniques . The major concern rests on the young if electronic cigarettes are released . Does that even with encouraging results on its ability smokefree , e-cigarettes would be an incentive for young people to become smokers ? In countries where the product has already been accepted , as in France , the sale to persons under 18 is prohibited .
