Hallucinogenic Drug
Hallucinogens are a large, diverse class of psychoactive drugs that can produce altered states of consciousness characterized by major alterations in thought, mood, and perception as well as other changes. Most hallucinogens can be categorized as either being psychedelics, dissociatives, or deliriants. However, certain hallucinogens such as Fly agaric as well as other gabaergic hallucinogenics are more often considered to technically be hypnotics, therefore indicating another separate subcategory of drugs which can substantially alter visual perception. Etymology The word ''hallucinogen'' is derived from the word ''hallucination''. The term ''hallucinate'' dates back to around 1595–1605, and is derived from the Latin ''hallūcinātus'', the past participle of ''(h)allūcināri'', meaning "to wander in the mind." Characteristics Leo Hollister gave five criteria for classifying a drug as hallucinogenic.Glennon RA. Classical drugs: an introductory overview. In Lin GC and Gle ...

Psychoactive Drug
A psychoactive drug, psychopharmaceutical, psychoactive agent or psychotropic drug is a chemical substance, that changes functions of the nervous system, and results in alterations in perception, mood, consciousness, cognition or behavior. These substances may be used medically, recreationally or spiritually to a. Purposefully improve one’s perceived performance b. Alter one's consciousness (such as with entheogens for ritual, spiritual or shamanic purposes) or c. For research. Some categories of psychoactive drugs - which are believed, by some, to have therapeutic value - may be prescribed by some physicians and other healthcare practitioners. Examples of medication categories that may contain potentially beneficial psychoactive drugs include, but are not limited to: # Anesthetics # Analgesics # Anticonvulsants # Anti-Parkinson’s medications # Medications used to treat Neuropsychiatric Disorders a. Antidepressants b. Anxiolytics c. Antipsychotics d. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salvinorin A
Salvinorin A is the main active psychotropic molecule in ''Salvia divinorum''. Salvinorin A is considered a dissociative hallucinogen. It is structurally distinct from other naturally occurring hallucinogens (such as DMT, psilocybin, and mescaline) because it contains no nitrogen atoms; hence, it is not an alkaloid (and cannot be rendered as a Salt (chemistry), salt), but rather is a terpenoid. It also differs in subjective experience, compared to other hallucinogens, and has been described as dissociative. Salvinorin A can produce psychoactive experiences in humans with a typical duration of action being several minutes to an hour or so, depending on the method of ingestion. Salvinorin A is found with several other structurally related Salvinorin, salvinorins. Salvinorin is a ''trans''-neoclerodane diterpenoid. It acts as a kappa opioid receptor agonist and is the first known compound acting on this receptor (biochemistry), receptor that is not an alkaloid. History Sa ...

Serotonergic
Serotonergic () or serotoninergic () means "pertaining to or affecting serotonin". Serotonin is a neurotransmitter. A synapse In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses are essential to the transmission of nervous impulses fr ... is serotonergic if it uses serotonin as its neurotransmitter. A serotonergic neuron ''produces'' serotonin. A substance is serotonergic if it produces its effects via interactions with the serotonin system, such as by stimulating or blocking neurotransmission. A serotonergic or serotoninergic agent is any chemical that modifies the effects of serotonin in the body. Some different types of serotonergics drugs include the following: * Serotonin receptor agonists and antagonists * Serotonin reuptake inhibitors * Serotonin releasing agents See also References Parasympathetic nervous system Neuroch ...

Dissociative Drug
Dissociatives, colloquially dissos, are a subclass of hallucinogens which distort perception of sight and sound and produce feelings of detachment – dissociation – from the environment and/or self. Although many kinds of drugs are capable of such action, dissociatives are unique in that they do so in such a way that they produce hallucinogenic effects, which may include dissociation, a general decrease in sensory experience, hallucinations, dream-like states or anesthesia. Some of these substances, which are nonselective in action and affect the dopamine and/or opioid systems, may be capable of inducing euphoria or symptoms which are more akin to the effects of certain “hard drugs” or common drugs of abuse. This is likely why dissociatives are considered to be addictive with a fair to moderate potential for abuse, unlike psychedelics. Despite some dissociatives, such as phencyclidine (PCP) possessing stimulating properties, most dissociatives seem to have a general depre ...

Psychedelic Drug
Psychedelics are a subclass of hallucinogenic drugs whose primary effect is to trigger non-ordinary states of consciousness (known as psychedelic experiences or "trips").Pollan, Michael (2018). ''How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence'' Sometimes, they are called classic hallucinogens, serotonergic hallucinogens, or serotonergic psychedelics, and the term ''psychedelics'' is used more broadly to include all hallucinogens; this article uses the narrower definition of ''psychedelics''. Psychedelics cause specific psychological, visual, and auditory changes, and often a substantially altered state of consciousness.Leary, Timothy; Metzner, Ralph (1964). ''The Psychedelic Experience: A Manual Based on The Tibetan Book of the Dead'' Psychedelic states are often compared to meditative, psychodynamic or transcendental types of alterations of mind.

Research Chemical
Research chemicals are chemical substances used by scientists for medical and scientific research purposes. One characteristic of a research chemical is that it is for laboratory research use only; a research chemical is not intended for human or veterinary use. This distinction is required on the labels of research chemicals, and is what exempts them from regulation under parts 100-740 in Title 21 of the Code of Federal Regulations ( 21CFR). Background Pharmacological research chemicals Research chemicals are fundamental in the development of novel pharmacotherapies. Common medical laboratory uses include ''in vivo'' and animal testing to determine therapeutic value, toxicology testing by contract research organizations to determine drug safety, and analysis by drug test and forensic toxicology labs for the purposes of evaluating human exposure. Many pharmacologically active chemicals are sold online under the guise of "research chemicals," when in reality they are unteste ...

25-NB
The 25-NB (25''x''-NB''x'') series, sometimes alternatively referred to as the NBOMe compounds, is a family of serotonergic psychedelics. They are substituted phenethylamines and were derived from the 2C family. They act as selective agonists of the serotonin 5-HT2A receptor. The 25-NB family is unique relative to other classes of psychedelics in that they are, generally speaking, extremely potent and relatively selective for the 5-HT2A receptor. Use of NBOMe series drugs has caused many deaths and hospitalisations since the drugs popularisation in the 2010s. This is primarily due to their high overdose potential and sellers passing off the compounds in the series as LSD. Chemical structure The 25-NB compounds are mostly ''N''-benzylphenethylamines, though in some cases the phenyl ring of the N-benzyl group is replaced by other heterocycles such as thiophene, pyridine, furan, tetrahydrofuran, benzodioxole or naphthalene, among others. Generally speaking, they have methoxy gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2C (psychedelics)
2C (2C-''x'') is a general name for the family of psychedelic phenethylamines containing methoxy groups on the 2 and 5 positions of a benzene ring. Most of these compounds also carry lipophilic substituents at the 4 position, usually resulting in more potent and more metabolically stable and longer acting compounds. Most of the currently known 2C compounds were first synthesized by Alexander Shulgin in the 1970s and 1980s and published in his book '' PiHKAL'' (''Phenethylamines i Have Known And Loved''). Shulgin also coined the term 2C, being an acronym for the 2 carbon atoms between the benzene ring and the amino group. Legality Canada As of October 12, 2016, the 2C-''x'' family of substituted phenethylamines is a controlled substance (Schedule III) in Canada.

Designer Drug
A designer drug is a structural or functional analog of a controlled substance that has been designed to mimic the pharmacological effects of the original drug, while avoiding classification as illegal and/or detection in standard drug tests. Designer drugs include psychoactive substances that have been designated by the European Union as new psychoactive substances (NPS) as well as analogs of performance-enhancing drugs such as designer steroids. Some of these were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects, and shorter duration (and possibly also because it is easier to apply for patents for new molecules) and were later co-opted for recreational use. Other designer drugs were prepared for the first time in clandestine laboratories. Because the efficacy and safety of these substances have not been thoroughly evaluated in animal and human trials, the use of some of these drugs may result i ...

David E
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, Dav ...

Phenomenology (psychology)
Phenomenology within psychology, or phenomenological psychology, is the psychological study of subjective experience. It is an approach to psychological subject matter that attempts to explain experiences from the point of view of the subject via the analysis of their written or spoken word. The approach has its roots in the phenomenological philosophical work of Edmund Husserl. Giorgi, Amedeo. (1970). ''Psychology as a Human Science.'' New York : Harper & Row. History of phenomenology Early phenomenologists such as Husserl, Jean-Paul Sartre, and Maurice Merleau-Ponty conducted philosophical investigations of consciousness in the early 20th century. Their critiques of psychologism and positivism later influenced at least two main fields of contemporary psychology: the phenomenological psychological approach of the Duquesne School (the descriptive phenomenological method in psychology), including Amedeo Giorgi Giorgi, Amedeo.
