Human behavior refers to the range of behaviors exhibited by humans and which are influenced by culture, attitudes, emotions, values, ethics, authority, rapport, hypnosis, persuasion, coercion and/or genetics.
The behavior of people (and other organisms or even mechanisms) falls within a range with some behavior being common, some unusual, some acceptable, and some outside acceptable limits. In sociology, behavior in general is characterised as having no meaning, being not directed at other people, and thus is the most basic human action. Behavior in this general sense should not be mistaken with social behavior, which is a more advanced action, as social behavior is behavior specifically directed at other people. The acceptability of behavior depends heavily upon social norms and is regulated by various means of social control. Human behavior is studied by the specialised academic disciplines of psychiatry, psychology, social work, sociology, economics, and anthropology.
Medicinal plants have been identified and used throughout human history. Toxic plants even have use in pharmaceutical development. Angiosperms (flowering plants) were the original source of most plant medicines. Some herbs and spices come from flowering plants.
Topics concerning medicinal plants include:
Medical cannabis refers to the parts of the herb cannabis used as a form of medicine or herbal therapy, or to synthetic forms of specific cannabinoids such as THC (delta-9-tetrahydrocannabinol) as a form of medicine. The plantCannabis has been used as a medicine over an extensive period of time. Cannabis is one of the 50 "fundamental" herbs of traditional Chinese medicine, and is prescribed for a broad range of indications.
However, organizations such as the American Society of Addiction Medicine dismiss the concept of medical cannabis because the plant in question fails to meet its standard requirements for approved medicines, as well as those of the United States (US)' Food and Drug Administration (FDA); that is, cannabis is associated with numerous harmful health effects, and significant aspects such as content, production, and supply are not regulated.
The effects of cannabis are caused by chemical compounds in cannabis, including cannabinoids such as tetrahydrocannabinol (THC). Cannabis has both psychological and physiological effects on the human body. Five European countries, Canada, and twenty US states have legalized medical cannabis if prescribed for nausea, pain or the alleviation of symptoms surrounding chronic illness.]citation needed[
In large enough doses, THC can induce auditory and visual hallucination. Acute effects while under the influence can include both euphoria and anxiety. Concerns have been raised about the potential for long-term cannabis consumption to increase risk for schizophrenia, depersonalization disorder, bipolar disorders, and major depression, however studies are inconclusive and the ultimate conclusions on these factors are disputed. The evidence of long-term effects on memory is preliminary and hindered by confounding factors. For thousands of years people have believed that cannabis has religious and spiritual effects.
Cannabis has been used in a religious and spiritual context in India since the Vedic period dating back to approximately 1500BCE but perhaps as far back as 2000BCE. There are several references in Greek mythology to a powerful drug that eliminated anguish and sorrow. Herodotus wrote about early ceremonial practices by the Scythians, thought to have occurred from the 5th to 2nd century BCE. Itinerant Hindu saints have used it in India for centuries.
In modern culture the spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use it for its natural consciousness exalting properties for their sacramental and sanctifying rites; according to what they know as belonging to the truthful and faithful prophetic way of life "livity" of the ancient mystics whose history is described in the sacred scriptures.
Cannabis smoking is the inhalation of smoke or vapors released by heating the flowers, leaves, or extracts of cannabis. Smoking releases the main psychoactive chemical in cannabis, Δ9-tetrahydrocannabinol (THC), which is absorbed into the bloodstream via the lungs.
Cannabis can be smoked, vaporized, consumed orally or applied to the skin; the bioavailability characteristics and effects of smoking and vaporizing cannabis differ from other consumption methods in having a more rapid and predictable onset of effect.
