Tobacco use is the cause of about 22% of cancer deaths.[2] Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol.[2][9][10] Other factors include certain infections, exposure to ionizing radiation and environmental pollutants.[3] In the developing world, 15% of cancers are due to infections such as Helicobacter pylori, hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV).[2] These factors act, at least partly, by changing the genes of a cell.[11] Typically, many genetic changes are required before cancer develops.[11] Approximately 5–10% of cancers are due to inherited genetic defects from a person's parents.[12] Cancer can be detected by certain signs and symptoms or screening tests.[2] It is then typically further investigated by medical imaging and confirmed by biopsy.[13]
The most common type of arthritis, osteoarthritis involves wear-and-tear damage to your joint's cartilage — the hard, slick coating on the ends of bones. Enough damage can result in bone grinding directly on bone, which causes pain and restricted movement. This wear and tear can occur over many years, or it can be hastened by a joint injury or infection.

Osteoarthritis affects more than 3.8% of people while rheumatoid arthritis affects about 0.24% of people.[9] Gout affects about 1–2% of the Western population at some point in their lives.[10] In Australia about 15% of people are affected,[11] while in the United States more than 20% have a type of arthritis.[8][12] Overall the disease becomes more common with age.[8] Arthritis is a common reason that people miss work and can result in a decreased quality of life.[7] The term is derived from arthr- (meaning joint) and -itis (meaning inflammation).[13][14]
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
Diabetes mellitus occurs throughout the world but is more common (especially type 2) in more developed countries. The greatest increase in rates has however been seen in low- and middle-income countries,[101] where more than 80% of diabetic deaths occur.[105] The fastest prevalence increase is expected to occur in Asia and Africa, where most people with diabetes will probably live in 2030.[106] The increase in rates in developing countries follows the trend of urbanization and lifestyle changes, including increasingly sedentary lifestyles, less physically demanding work and the global nutrition transition, marked by increased intake of foods that are high energy-dense but nutrient-poor (often high in sugar and saturated fats, sometimes referred to as the "Western-style" diet).[101][106] The global number of diabetes cases might increase by 48% between 2017 and 2045.[8]
There are many ways a person can find more information about cancer, but if they have any immediate concerns about having cancer, their first source of information should be their doctor. In addition to the references listed at the end of this article, the following is a list of information sources that are well recognized as authorities for cancer information by most clinicians:

CA 125 is a protein, and a tumor marker or biomarker. CA 125 is present in greater concentration in ovarian cancer cells than in other cells. CA stands for cancer antigen. Increases in CA 125 can also occur with malignant tumors of the Fallopian tubes, lining of the uterus, lung, breast, and gastrointestinal track. Benign conditions such as infections of the abdomen, chest, menstruation, endometriosis, benign tumors of the ovaries, and liver disease can also raise CA 125.
Some treatments can interfere with the mother's ability to give birth vaginally or to breastfeed.[219] Cervical cancer may require birth by Caesarean section. Radiation to the breast reduces the ability of that breast to produce milk and increases the risk of mastitis. Also, when chemotherapy is given after birth, many of the drugs appear in breast milk, which could harm the baby.[219]
There is no known preventive measure for type 1 diabetes.[2] Type 2 diabetes—which accounts for 85–90% of all cases worldwide—can often be prevented or delayed by maintaining a normal body weight, engaging in physical activity, and eating a healthy diet.[2] Higher levels of physical activity (more than 90 minutes per day) reduce the risk of diabetes by 28%.[71] Dietary changes known to be effective in helping to prevent diabetes include maintaining a diet rich in whole grains and fiber, and choosing good fats, such as the polyunsaturated fats found in nuts, vegetable oils, and fish.[72] Limiting sugary beverages and eating less red meat and other sources of saturated fat can also help prevent diabetes.[72] Tobacco smoking is also associated with an increased risk of diabetes and its complications, so smoking cessation can be an important preventive measure as well.[73]

Palliative therapy (medical care or treatment used to reduce disease symptoms but unable to cure the patient) utilizes the same treatments described above. It is done with the intent to extend and improve the quality of life of the terminally ill cancer patient. There are many other palliative treatments to reduce symptoms such as pain medications and antinausea medications.

Hash oil, also known as honey oil or cannabis oil, is an oleoresin obtained by the extraction of cannabis or hashish. It is a concentrated form of the plant containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. There are various extraction methods, most involving a solvent, such as butane or ethanol. Hash oil is usually consumed by smoking, vaporizing or eating. Hash oil may be sold in cartridges used with pen vaporizers. Preparations of hash oil may be solid or colloidal depending on both production method and temperature and are usually identified by their appearance or characteristics. Range of color, most commonly golden to light brown, can vary from transparent to yellow, to tan or black, this mainly depends on the method of preparation and solvent, if the solvent also reacts with plant material and chlorophyll, the oil procured would not yellow coloured, it would be green instead.. Cannabis retailers in California have reported about 40% of their sales are from cannabis oils.[1]
Low blood sugar (hypoglycemia) is common in people with type 1 and type 2 DM. Most cases are mild and are not considered medical emergencies. Effects can range from feelings of unease, sweating, trembling, and increased appetite in mild cases to more serious effects such as confusion, changes in behavior such as aggressiveness, seizures, unconsciousness, and (rarely) permanent brain damage or death in severe cases.[23][24] Moderately low blood sugar may easily be mistaken for drunkenness;[25] rapid breathing and sweating, cold, pale skin are characteristic of low blood sugar but not definitive.[26] Mild to moderate cases are self-treated by eating or drinking something high in sugar. Severe cases can lead to unconsciousness and must be treated with intravenous glucose or injections with glucagon.[27]
Metformin is generally recommended as a first line treatment for type 2 diabetes, as there is good evidence that it decreases mortality.[6] It works by decreasing the liver's production of glucose.[87] Several other groups of drugs, mostly given by mouth, may also decrease blood sugar in type II DM. These include agents that increase insulin release, agents that decrease absorption of sugar from the intestines, and agents that make the body more sensitive to insulin.[87] When insulin is used in type 2 diabetes, a long-acting formulation is usually added initially, while continuing oral medications.[6] Doses of insulin are then increased to effect.[6][88]

As of November 2016, 33 states and the District of Columbia legally allow cannabis for personal medical use. Rules surrounding the use of medical cannabis (medical marijuana) vary by state. The first state in the union to legalize the medical use of marijuana was California in 1996. States that allow medical marijuana include: Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nevada, New Hampshire, New Jersey, New Mexico, North Dakota, New York, Ohio, Oregon, Pennsylvania, Rhode Island, Utah, Vermont, Washington, and the District of Columbia. It is important to recognize that these state marijuana laws do not change the fact that using marijuana continues to be an offense under Federal law.
It's a little more uniform when the product is absorbed by smoking or vaping the oil, Ward said. But, "there are obvious concerns about smoking something." A 2007 review published in the journal JAMA Internal Medicine found that smoking marijuana resulted in similar declines in respiratory system health as smoking tobacco. A similar review published in 2014 in The American Journal of Cardiology found that marijuana smoke inhalation can increase the chances of heart attack or stroke. Neither review analyzed the effects of vaping cannabis oil alone, so it's unclear if it has the same health risks as smoking other marijuana products.
