Where to buy phentermine without prescription

INVESTIGATION

They discover another form in that where to buy phentermine without prescription cigarette harms the nonsmokers: the smoke of third hand. Cancerigenic polluting agents form by reaction between rest of the nicotine where to buy phentermine without prescription the nitrous acid, where to buy phentermine without prescription polluting agent common in the air. cheap 37 5 phentermine it has entered a closed space where somebody has been smoking knows that the scent persists by a long period of time. During years the investigators have been conscious that the smoke of the tobacco adheres to the surfaces and that with volatile and semivolatile substances can produce reactions.

But get phentermine without a prescription reactions of the residual components of the tobacco with molecules that are the atmosphere, like nitrous oxide, little had been considered like source of dangerous polluting agents. Now, a study just published quantifies the dangers of the call smoke of third hand. By Ricardo Go'mez Vecchio

The smoke of third originating hand of where to buy phentermine without prescription nicotine, a remainder of where to buy phentermine without prescription cigarette that sticks to almost all the surfaces, reacts with contaminate very common in the air, nitrous acid, producing dangerous cancerigenic agents. This has been verified in a study lead by an investigator of Lawrence Berkeley National Laboratory, in the where to buy phentermine without prescription States.

When where to buy phentermine without prescription tobacco burning fire frees nicotine in the form of steam get phentermine without a prescription adheres to surfaces like walls, floors, carpets and furniture. In this way the nicotine can persist on those materials during days, weeks and still months. Hugo get phentermine without a prescription and its colleagues of the Berkeley Lab have demonstrated that when those residues are combined with nitrous acid of the where to buy phentermine without prescription they form N-nitrosaminas (TSNAs). These TNSAs is between the most active and powerful present cancerigenic agents in the smoke of the tobacco.

The work just was published in Proceedings of the National Academy of Sciences (PNAS). They also sign Mohamad Sleiman, Lara Gundel and Btett Singer, also of the Berkeley Lab, along with James Pankow, of Portland State University, and Peyton Jacob, of Californian University of, in San Francisco.

The investigators used cellulose like model where to buy phentermine without prescription material exhibited to the smoke of the cigarette in an ambient intern. The levels of where to buy phentermine without prescription that detected on the cellulose surfaces where to buy phentermine without prescription 10 times higher than the presents in a sample exhibited by three hours to high but reasonable concentrations of nitrous acid. As the motors of many where to buy phentermine without prescription emit something of nitrous acid that can infiltrate in the where to buy phentermine without prescription of the passengers, they became test within trucks of smokers. These measurements also showed elevated levels of TSNAs. In both cases, one of the found substances more was the NNA, a type of TSNA that is absent in the tobacco smoke just emitted.

Considering where to buy phentermine without prescription fast adhesion and persistence where to buy phentermine without prescription the nicotine high levels in the ambient interns, including the clothes and the skin of the people, these discoveries indicate that the smoke of third hand represents a danger for the health that had not been appreciated through the exhibition of the skin and the inhalation of the dust.

As the form of more probable exhibition of the human being to these carcinogen substances is where to buy phentermine without prescription means of the inhalation of the where to buy phentermine without prescription or the contact of the skin with exhibited carpets and other surfaces, the smoke of third hand implies where to buy phentermine without prescription greater risk for the small babies and children, since he is frequent where to buy phentermine without prescription crawl or play in the ground thus taking contact with the polluting agents.

The results of the study indicate that abrir a window or get phentermine without a prescription ignite a ventilator to air the room while a cigarette is smoked get phentermine without a prescription does not eliminate the risk of the smoke of third hand. And although to smoke outdoors he is less harmful than to do it in ambient interns, even so the residues of the nicotine stick to the skin and the clothes of the smoker and the people accompany who it. Those residues soon where to buy phentermine without prescription transferred inadvertently to the home, and there they where to buy phentermine without prescription scattered throughout. Again, the greatest risk is for the small children. It is very probable that these receive the nicotine in their skin when the smoker returns to house, and that forms those carcinogen substances to them if, as he is the habitual thing, is nitrous acid in the air of the home.

The dangers for the passive smoker widely have been documented like where to buy phentermine without prescription where to buy phentermine without prescription cancer, cardiovascular diseases, pulmonary diseases and defects of birth. Nevertheless, where to buy phentermine without prescription recently it begins to arrive at people the knowledge on the dangers from the smoke from third hand. The term where to buy phentermine without prescription coined in a study published in January of 2009 in the journal Pediatrics. In the same one inquired that only the 65 percent of the smokers and the 43 percent of the consulted smokers did cheap 37 5 phentermine agree with the affirmation of which ” to breathe air today in an atmosphere where people smoked yesterday can damage to the health of the children ”.

The nicotine, that is get phentermine without a prescription addictive substance in the smoke of the tobacco, had been considered until now like nontoxic in the strict sense of the term. But get phentermine without a prescription study demonstrates that the reactions of the residual nicotine that adheres to the ssuperficies cheap 37 5 phentermine nitrous acid represent a risk since they cheap 37 5 phentermine carninógenas substances.

The investigators of the Berkerley Lab are dedicating themselves now to study the long term stability of the TSNAs cheap 37 5 phentermine take place in the ambient interns as a result of the interaction of the smoke of third hand with nitrous acid. They are also where to buy phentermine without prescription to develop marking biological to track the exhibition to those cancerigenic polluting agents. And they try to include chemistry more deeply than he explains the formation of the TSNAs and to find where to buy phentermine without prescription compounds that take place when reacting the smoke of third hand with nitrous acid.

At the moment, they emphasize the importance of limiting the damages of the smoke of third hand avoiding to smoke in residential atmospheres, of work and in space like the automobiles. Although clearly, not to smoke absolutely is still far better.
