Health effects of tobacco
Tobacco use has predominantly negative effects on human health and concern about health effects of tobacco has a long history. Research has focused primarily on cigarette smoking.
Tobacco smoke contains more than 70 chemicals that cause cancer. Tobacco also contains nicotine, which is a highly addictive psychoactive drug. When tobacco is smoked, nicotine causes physical and psychological dependency.
Tobacco use is the single greatest cause of preventable death globally. As many as half of people who use tobacco die from complications of tobacco use.The World Health Organization (WHO) estimates that each year tobacco causes about 6 million deaths (about 10% of all deaths) with 600,000 of these occurring in non-smokers due to second-hand smoke.
Tobacco use most commonly leads to diseases affecting the heart, liver and lungs. Smoking is a major risk factor for infections like pneumonia, heart attacks, strokes, chronic obstructive pulmonary disease and multiple cancers. It also causes peripheral arterial disease and high blood pressure. Starting smoking earlier in life and smoking cigarettes higher in tar increases the risk of these diseases. Also, environmental tobacco smoke, or second-hand smoke, has been shown to cause adverse health effects in people of all ages.

Beverage

A drink (or beverage) is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, coffee, tea, hot chocolate, juice and soft drinks. In addition, alcoholic drinks such as wine, beer, and liquor, which contain the drug ethanol, have been part of human culture for more than 8,000 years.


Non-alcoholic drinks often signify drinks that would normally contain alcohol, such as beer and wine, but are made with less than 5 percent alcohol by volume. The category includes drinks that have undergone an alcohol removal process such as non-alcoholic beers and de-alcoholized wines.


Types of drink


Non-alcoholic drinks
A non-alcoholic drink is one that contains little or no alcohol. This category includes low-alcohol beer, non-alcoholic wine, and apple cider if they contain less than 0.5% alcohol by volume. The term "soft drink" specifies the absence of alcohol in contrast to "hard drink" and "drink". The term "drink" is theoretically neutral, but often is used in a way that suggests alcoholic content. Drinks such as soda pop, sparkling water, iced tea, lemonade, root beer, fruit punch, milk, hot chocolate, tea, coffee, milkshakes, and tap water and energy drinks are all soft drinks.


Water
Water is the world's most consumed drink, however, 97% of water on Earth is non-drinkable salt water. Fresh water is found in rivers, lakes, wetlands, groundwater, and frozen glaciers. Less than 1% of the Earth's fresh water supplies are accessible through surface water and underground sources which are cost effective to retrieve.
In western cultures, water is often drunk cold. In the Chinese culture, it is typically drunk hot.


Milk
Regarded as one of the "original" drinks, milk is the primary source of nutrition for babies. In many cultures of the world, especially the Western world, humans continue to consume dairy milk beyond infancy, using the milk of other animals (especially cattle, goats and sheep) as a drink. Plant milk, a general term for any milk-like product that is derived from a plant source, also has a long history of consumption in various countries and cultures. The most popular varieties internationally are soy milk, almond milk, rice milk and coconut milk.


Soft drinks
Carbonated drinks refer to drinks which have carbon dioxide dissolved into them. This can happen naturally through fermenting and in natural water spas or artificially by the dissolution of carbon dioxide under pressure. The first commercially available artificially carbonated drink is believed to have been produced by Thomas Henry in the late 1770s. Cola, orange, various roots, ginger, and lemon/lime are commonly used to create non-alcoholic carbonated drinks; sugars and preservatives may be added later.
Juice and juice drinks
Fruit juice is a natural product that contains few or no additives. Citrus products such as orange juice and tangerine juice are familiar breakfast drinks, while grapefruit juice, pineapple, apple, grape, lime, and lemon juice are also common. Coconut water is a highly nutritious and refreshing juice. Many kinds of berries are crushed; their juices are mixed with water and sometimes sweetened. Raspberry, blackberry and currants are popular juices drinks but the percentage of water also determines their nutritive value. Grape juice allowed to ferment produces wine.
Fruits are highly perishable so the ability to extract juices and store them was of significant value. Some fruits are highly acidic and mixing them with water and sugars or honey was often necessary to make them palatable. Early storage of fruit juices was labor-intensive, requiring the crushing of the fruits and the mixing of the resulting pure juices with sugars before bottling.
Vegetable juices are usually served warm or cold. Different types of vegetables can be used to make vegetable juice such as carrots, tomatoes, cucumbers, celery and many more. Some vegetable juices are mixed with some fruit juice to make the vegetable juice taste better. Many popular vegetable juices, particularly ones with high tomato content, are high in sodium, and therefore consumption of them for health must be carefully considered. Some vegetable juices provide the same health benefits as whole vegetables in terms of reducing risks of cardiovascular disease and cancer.


Sleep drinks
A nightcap is a drink taken shortly before bedtime to induce sleep. For example, a small alcoholic drink or a cup of warm milk can supposedly promote a good night's sleep. Today, most nightcaps and relaxation drinks are generally non-alcoholic beverages containing calming ingredients. They are considered beverages which serve to relax a person. Unlike other calming beverages, such as tea, warm milk or milk with honey; relaxation drinks almost universally contain more than one active ingredient. Relaxation drinks have been known to contain other natural ingredients and are usually free of caffeine and alcohol.
