Smoking bans are the most preferred and implemented measures taken up in order to combat the epidemic of smoking addiction. The smoking bans found easy implementation following the fact that smoking is an evil that also has characteristics like passive smoking and contaminating the environment at large. In most of the developed countries smoking has been banned indoors. Even in the places like pubs and restaurants where smoking was a common sight and a trend the ban has been implemented. In many of the countries the concerned authorities have also gone a step further and passed smoking bans in the outdoors like the parking lots, roads, schools vicinity etc. People are also found to be warmly welcoming the acts for the greater good of the society and the smokers have no other choice but to accept the rules. They can definitely go against the laws but at the risk of paying huge penalties. So it is natural that people decide otherwise.

However, banning of smoking is not all that easy as it seems to be. The governments or the concerned authorities have to take many related issues into account. Various financial, political, and social issues have to be addressed in order to take steps like banning of one of the most pervasive and revenue generating addictions.

US have one of the largest smoking addicted populations. It is nothing short of an epidemic in this country, in fact in US huge expenses are incurred in treating the smoking related illnesses. The human resource that it was losing was another matter of grave concern and hence the need of smoking bans. There was however, a very major hurdle towards achieving this goal. The US constitution prevents the implementation of any form of smoking ban in the country by the United States Congress under the federal law. This rule is laid down in Article One of the constitution. But as they say, where there is a will there is a way. Different states of USA came up with smoking bans in their respective states as according to the Tenth Amendment of the Constitution the power to enact smoking bans were vested with the states. Thus, the purpose was solved without making the extreme move of violating the Constitution of the country.

This is a lesson to learn from for India which is also a country where smoking is extremely widespread. India also has a large number of people addicted to chewing tobacco. Still India has not experienced any effective smoking bans as of now. In India the Amendment of the Constitution also becomes a very thorny subject primarily because of the innumerable number of parties existing in this country. But where the matter of public welfare comes in, all the other differences should be kept aside and a way out should be sought amicably. It is indeed sad when the Constitution which is for the welfare of the people, comes in the way of its very purpose.

Today, giving up the addiction of smoking has become easier with the help of the quit smoking drugs. Pfizer chantix is a popular quit smoking pill. The drug is easily available in the online pharmacies from where you can buy chantix online. The chantix side effects can be dangerous at times hence the prescription is mandatory. The good news is that the drug is marketed online and no constitution objects to buying or selling of quit smoking drugs.

Determine Whether Vitamin A Enhances Immune Response

Several approaches have been taken in an attempt to determine whether Vitamin A supplementation enhances immune response and resistance or recovery from infection. In some investigations, researchers have attempted to correlate plasma concentrations of beta-carotene or retinol with immune response or susceptibility to infection. One limitation of this approach is related to the fact that plasma concentrations may have depressed plasma retinol levels as a result of disease. Therefore, it is not possible to establish whether low plasma retinol levels resulted in suppressed immune response or if plasma retinol levels decreased in response to disease or infection. Another approach used is to supplement the diet with retinol precursors and examine immune response at a later time point. This approach may be useful in examining the particular aspects of immunity that may be altered by supplementation, but additional studies are necessary to determine whether these effects have clinical significance in terms of disease outcome. Vitamin A has been fairly well studied in terms of its immunomodulatory effects, and we will review the evidence from randomized controlled trials as well as potential mechanisms of action. Vitamin A supplementation may afford some protection from infection in malnourished individuals, but the potential benefits of supplementation in normal wellnourished individuals remain to be established. There is evidence from several studies that suggests that vitamin A deficiency is associated with depressed immune function and an impaired response to influenza infection. Supplementation of vitamin A is associated with a reduction of mortality and morbidity among certain populations. It appears that populations suffering from malnutrition may benefit from adequate or additional vitamin A supplementation. However, it is less clear if normal, healthy, well-nourished individuals will benefit from additional supplementation with respect to enhanced immunity. The results from several studies involving beta-carotene supplementation in the diet of healthy individuals suggest that certain aspects of innate immunity, such as NK cytotoxicity and monocyte production of the cytokine TNFcx, are enhanced. It appears that lymphocyte subsets or the lymphocyte response to mitogens are not altered. In addition, one study of healthy older individuals found that vitamin A supplementation was associated with a reduction in the number of T lymphocytes. Whether these observed changes of immune function in response to supplementation actually result in reduced susceptibility to infection in healthy individuals is not well established. The results from one study demonstrated no association between vitamin A supplementation and incidence of bacterial infection. we are not aware of any long-term, randomized clinical trials that have evaluated the incidence of viral infection in response to supplementation with vitamin A alone. However, several studies have examined the possibility that supplementation with several multivitamins and or trace elements such as zinc, may alter susceptibility to infection. In general, the findings from these studies show no protection from infection in association with vitamin intake, but a slight decrease in the incidence of infection in those individuals consuming supplemental trace elements such as zinc and selenium. At this time, the potential benefits of vitamin A supplementation for healthy well-nourished individuals regarding susceptibility to infection remain to be established. A high beta-carotene intake has also been associated with a reduced risk of cancer. Earlier epidemiological studies suggested a high natural (fruits and vegetables) intake of beta-carotene was associated with reduced risk of cancer. However, more recent studies have not observed any benefit of beta-carotene intake on incidence of cancer and two studies actually observed an increased incidence of lung cancer in those participants consuming beta-carotene supplements. The presence of other carotenoids in fruits and vegetables has been suggested to be the protective factor in regards to cancer incidence in the early epidemiological studies based on the findings from these recent studies, dietary supplementation with high doses of synthetic beta-carotene may be contraindicated for smokers. As a reminder, it has been known for some time that a high intake of vitamin A results in adverse effects (neurologic, dermatologic, musculoskeletal, gastrointestinal, birth defects) and the results from the most recent studies suggest a potential risk of high doses of synthetic beta-carotene in certain populations. At this time it is probably safest to follow the National Cancer Institute recommendations that suggest five or more servings of fruits and vegetables per day. Immune Effects and Exercise We are currently aware of only one study that has examined whether vitamin A supplementation is associated with a reduced incidence of infection in athletes. Several studies have shown that the risk of upper respiratory infection is increased following competition in marathons or ultramarathons However, vitamin A supplementation before marathon competition did not reduce the incidence of infection in the postrace period. Therefore, to our knowledge, vitamin A supplementation has not been associated with enhanced resistance to infection in healthy athletes.

Today it is highly recommended that certain individuals obtain the flu vaccine in order to avoid contracting this virus, which can be highly dangerous for the elderly and persons with weakened immune systems. Despite this advice by medical professionals; however, many year innumerable people continue to ignore this advice due to concerns regarding the safety of the flu vaccine. As a result, more than 20,000 people continue to die in the United States as a result of flu related complications.

The flu vaccine is manufactured using an inactivated or killed viral vaccine. During the manufacturing process, the flu viruses are actually grown inside chicken eggs and then are later harvested. A chemical process is used to kill the live flu virus. After purification and testing for safety, the vaccine is ready to be used in order to vaccinate humans.

There are actually many different varieties of the flu. Researchers and scientists determine which strains will be most predominant during the upcoming flu seasons and use these strains in the manufacturing process of the flu vaccines for that upcoming season.

Of course, no vaccine is 100% effective; however, the flu vaccine has proven to be quite effective in preventing the contraction of the flu. This depends; however, on the selection of the flu strains to be used in the production of the vaccine. If researchers and scientists inaccurately predict which strains will be most predominant during the coming flu season, then the vaccine will not be as effective. Generally, when the right strains are chosen and matched for the vaccine production, it is anticipated that the vaccine can be up to 90% effective. This percentage only relates to healthy adults; however, and does not take into consideration the very young or the elderly. The percentage of effectiveness will be lower in these populations. In fact, research estimates that the percentage of effectiveness in these populations may be as low as 30%. Despite these low percentages in person who are considered to be frail; however, the flu vaccine has shown to be capable of protecting against some of the most severe complications of the flu; including pneumonia; which can lead to hospitalization and death.

Usually, most flu vaccine campaigns are begun in October and conducted throughout November due to the fact that most outbreaks of the flu tend to occur in the winter. The vaccine is administered using a needle in a shot given to the arm. The liquid vaccine then penetrates to the muscle. Persons who have had the vaccine previously will only require one shot; however, persons who have not previously had the vaccine will need two shots, spaced one month apart.

Each year flu vaccine recommendations are issued based on a variety of factors. Usually it is recommended that all persons who are aged 50 are older should obtain the flu vaccine, as well as residents of nursing homes, persons with chronic heart and lung diseases, children with asthma, persons with diabetes and hemoglobin disorders, persons with weakened immune systems such as transplant and cancer patients, persons with HIV and anyone receiving chemotherapy or radiation therapy. In addition, all health care workers, persons caring for people in high-risk groups, children ages 6 months to 18 years who are at risk for developing Reye Syndrome and women in the second and third trimester of pregnancy during the flu season.

The flu vaccine is considered to be safe for almost everyone; although, there are some situations in which you should not get the vaccine. These situations include persons who are allergic to eggs and acute illness with fever.
