National Institute on Alcohol Abuse and Alcoholism provides leadership in the national effort to reduce alcohol-related problems by conducting and supporting research in a wide range of scientific areas, including genetics, neuroscience, epidemiology, health risks and benefits of alcohol consumption, prevention and treatment; coordinating and collaborating with other research institutes and Federal programs on alcohol-related issues; collaborating with international, national, State and local institutions, organizations, agencies and programs engaged in alcohol-related work; and translating and disseminating research findings to health care providers, researchers, policymakers and the public.

Ketamine

At lower doses, ketamine acts a weak stimulant. When dosage increases, ketamine hits users as an intense psychedelic. As a dissociative drug, ketamine causes users to feel painlessness by impeding messages between the brain and body. Ketamine distorts perception and users often experience an effect known as "the K-hole" at high doses, where the reality of a user involves abstracted thought and pseudo-spiritual experiences. In fact, many ketamine users report depersonalization and de-realization, causing out-of-body or near death experiences. While some ketamine users find these dissociative effects pleasant, others experience them as a deep sense of loneliness or emptiness. Hallucinations, both visual and auditory, can also take place during a ketamine trip. Ketamine trips do not tend to lend themselves to social interaction at high doses, but are introspective experiences as users withdraw into themselves. Within 10 to 20 minutes, the effects of ketamine become discernable for users. Muscle paralysis sets in, making it difficult to move. Ketamine users often fall into a "trance" state, finding themselves encountering difficulty speaking and cognitively processing. Ketamine trips are short lived, lasting between 45 minutes and an hour and a half, depending on tolerance. Users often feel drained and exhausted after a ketamine trip and muscle aches often tend to set in as users come down from a ketamine high. Ketamine users experience temporary paralysis of the muscles, loss of physical coordination and become prone to accidental falls and injuries. Research studies indicate that ketamine addiction can lead to brain damage, particularly the formation of vacuoles, also known as "Olney’s lesions." Ketamine use does not usually result in overdoses from self-administered use, largely because unconsciousness sets in before the body reaches the level of overdose. However, if ketamine a user intakes ketamine from a third party, overdose can occur if dosage continues after loss of consciousness.

Vitiligo

Vitiligo or leukoderma is a chronic skin disease that causes loss of pigment, resulting in irregular pale patches of skin. The precise cause of vitiligo is complex and not fully understood. There is some evidence that suggests a combination of autoimmune, genetic and environmental factors causes vitiligo. The incidence of vitiligo worldwide is between one and two percent. According to the Diseases Database, the disorder appears in of areas of macular depigmentation, commonly on extensor aspects of extremities, on the face or neck, and in skin folds. The age of onset is often in young adulthood and the condition tends to progress gradually with lesions enlarging and extending until a quiescent state is reached. Half of the people living with vitiligo develop patches of de-pigmented skin appearing on extremities before their 20s. The patches may grow, shrink or remain constant in size. Patches often occur symmetrically across both sides on the body. Occasionally small areas may re-pigment as they are recolonised by melanocytes. The location of vitiligo affected skin changes over time, with some patches re-pigmenting and de-pigmenting.

Advanced Skin Products

The most advanced skin products penetrate deeper where skin problems start. They can alleviate spider veins, loose skin, skin firming on the eyes, neck, face and body, stretch marks on thighs and the breasts and more! Under-eye puffiness is usually only a temporary cosmetic concern and rarely a sign of a serious underlying medical condition. Some tips for reducing mild under-eye puffiness are: Raise the height of the head while in bed at night. This helps prevent fluids from accumulating around the eyes during sleep. While sitting up, apply a cool tap water compress to the skin under the eyes for a few minutes. Chilled cucumber slices, a refrigerated gel mask or chilled, damp tea bags also work well. Sunscreen agents prevent sunburn. Limiting exposure to the sun and using sun block and sunscreen when in the sun may help prevent early wrinkling and skin cancer. There are two kinds of sunscreen agents: chemical and physical. Chemical sunscreen agents protect the skin from the sun by absorbing the ultraviolet (UV) and visible sunrays, while physical sunscreen agents reflect, scatter, absorb or block these rays.
