Amphetamine Dependence
Amphetamine dependence refers to a state of psychological dependence on a drug in the amphetamine class. Stimulants such as amphetamines and cocaine do not cause somatic symptoms upon cessation of use but rather neurological-based mental symptoms. Signs of amphetamine intoxication manifest themselves in euphoria, hypersexuality, tachycardia, diaphoresis, and intensifications of the train of thought, speech, and movement. Over time, neurodegenerative changes become apparent in the form of altered behavior, reduced cognitive functions, and signs of neurological damage, such as a decrease in the levels of dopamine transporters (DAT) and serotonin transporters (SERT) in the brain. Amphetamine use within teenagers can have lasting effects on their brain, in particular the prefrontal cortex. Amphetamine use is rising among students due to the ability to easily access prescribed stimulants like Adderall. Also, in case of chronic use, vegetative disorders soon occur such as bouts of swea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anesthetic
An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness. They may be divided into two broad classes: general anesthetics, which result in a reversible loss of consciousness, and local anesthetics, which cause a reversible loss of sensation for a limited region of the body without necessarily affecting consciousness. A wide variety of drugs are used in modern anesthetic practice. Many are rarely used outside anesthesiology, but others are used commonly in various fields of healthcare. Combinations of anesthetics are sometimes used for their synergistic and additive therapeutic effects. Adverse effects, however, may also be increased. Anesthetics are distinct from analgesics, which block only sensation of painful stimuli. Analgesics are typically used in conjunction with anesthetics to control pre-, intra-, and postop ...

The palm is originally native to the Philippines, but was carried widely through the tropics by the Austronesian migrations and trade since at least 1500 BCE due to its use in betel nut chewing. It is widespread in cultivation and is considered naturalized in much of the tropical Pacific (Melanesia and Micronesia), South Asia, Southeast Asia, and parts of east Africa. It is not to be confused with betel (''Piper betle'') leaves that are often used to wrap it. The practice of betel nut chewing, often together with other herbs as a stimulant drug, dates back thousands of years, and continues to the present day in many countries.
