4-FA
4-Fluoroamphetamine (4-FA; 4-FMP; PAL-303; "Flux"), also known as ''para''-fluoroamphetamine (PFA) is a psychoactive research chemical of the phenethylamine and substituted amphetamine chemical classes. It produces stimulant and entactogenic effects. As a recreational drug, 4-FA is sometimes sold along with related compounds such as 2-fluoroamphetamine and 4-fluoromethamphetamine. Usage 4-FA is popular in the Netherlands where it is predominantly used for its specific effects (77% of users) rather than its legal status (18%). 4-FA has become illegal since May 2017. Effects The subjective effects of 4-fluoroamphetamine include euphoria which some find similar to the effects of MDMA and amphetamine, increased energy (stimulation), mood elevation, feelings of warmth and empathy, excessive talking, bruxism, and suppressed appetite (anorexic). The general course of effects involves primarily empathogenic effects for the first few hours, which fades out as increased stimulation d ...

Liebermann Reagent
The Liebermann reagent named after Hungarian chemist Leo Liebermann (1852-1926) is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of potassium nitrite and concentrated sulfuric acid. 1 g of potassium nitrite is used for every 10 mL of sulfuric acid. Potassium nitrite may also be substituted by sodium nitrite. It is used to test for cocaine, morphine, Para-Methoxyamphetamine, PMA and Para-Methoxymethamphetamine, PMMA. The test is performed by scraping off a small amount of the substance and adding a drop of the reagent (which is initially clear and colorless). The results are analyzed by viewing the color of the resulting mixture, and by the time taken for the change in color to become apparent.

4-fluoromethamphetamine
4-Fluoromethamphetamine (4-FMA) is a stimulant drug related to methamphetamine and 4-fluoroamphetamine. It has been reported to be sold as a designer drug, but little is known about its pharmacology or toxicology. It was first detected from legal highs sold in Japan in 2006 and became illegal to sell or to possess for the purpose of distribution (although not to simply possess for personal use) in Japan in 2008. It was initially reported to be contained as an ingredient in some of the range of party pills sold internationally by the Israeli company Neorganics from around 2006 onwards, but this was later shown to be incorrect and this ingredient was eventually identified as the closely related compound 2-fluoromethamphetamine. Pharmacology 4-FMA is a CYP450 inhibitor. It reduces the metabolism of methamphetamine, which has the effect of increasing its potency, duration and systemic toxicity while also reducing its cellular toxicity. Legal status Australia 4-FMA is considered a Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substituted Amphetamine
Substituted amphetamines are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, bupropion, methoxyphenamine, selegiline, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and DOM (STP). Some of amphetamine's substituted derivatives occur in nature, for example in the leaves of ''Ephedra'' and khat plants. Amphetamine was first produced at the end of the 19th century. By the 1930s, amphetamine and some of its derivative compounds found use as decongestants in the symptomatic treatment of colds and also occasionally as psychoac ...

4-methylamphetamine
4-Methylamphetamine (4-MA; PAL-313; Aptrol; p-TAP) is a stimulant and anorectic drug of the phenethylamine and amphetamine chemical classes. In vitro, it acts as a potent and balanced serotonin, norepinephrine, and dopamine releasing agent with Ki affinity values of 53.4nM, 22.2nM, and 44.1nM at the serotonin, norepinephrine, and dopamine transporters, respectively. However, more recent ''in vivo'' studies that involved performing microdialysis on rats showed a different trend. These studies showed that 4-methylamphetamine is much more potent at elevating serotonin (~18 x baseline) relative to dopamine (~5 x baseline). The authors speculated that this is because 5-HT release dampens DA release through some mechanism. For example, it was suggested that a possible cause for this could be activation of 5HT2C receptors since this is known to inhibit DA release. In addition there are alternative explanations such as 5-HT release then going on to encourage GABA release, which has an ...

Reagent Testing
Reagent testing is one of the processes used to identify substances contained within a pill, usually illicit substances. With the increased prevalence of drugs being available in their pure forms, the terms "drug checking" or "pill testing" may also be used, although these terms usually refer to testing with a wider variety of techniques covered by drug checking. Reagent testing notes A test is done by taking a small scraping from a pill and placing it in the reagent testing liquid or dropping the reagent onto the scraping. The liquid will change colour when reacting with different chemicals to indicate the presence of certain substances. Testing with a reagent kit does not indicate the pill is safe. While the testing process does show some particular substances are present, it may not show a harmful substance that is also present and unaccounted for by the testing process. Some substances that cause strong colour changes can also mask the presence of other substances that caus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marquis Reagent
Marquis reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of formaldehyde and concentrated sulfuric acid, which is dripped onto the substance being tested. The United States Department of Justice method for producing the reagent is the addition of 100 mL of concentrated (95–98%) sulfuric acid to 5 mL of 40% formaldehyde. Different compounds produce different color reactions. Methanol may be added to slow down the reaction process to allow better observation of the colour change. It was first discovered in 1896Toxicology. Volume 2 : mechanisms and analytical methods — New York, New York ; San Francisco, California : Academic Press, 1961 — p. 247. and described by the Russian (Estonian) pharmacologist, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oral Administration
Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example. Oral administration can be easier and less painful than other routes, such as injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients willing and able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandelin Reagent
The Mandelin reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of ammonium metavanadate and concentrated sulfuric acid. Its primary use is for the detection of ketamine and PMA Unlike the most common reagent test chemicals, it has a deep red colour that changes to yellow if there is no alkaloid, which occurs within about 48 hours of mixing. The United States Department of Justice method for producing the reagent is the addition of 100 mL of concentrated (95–98%) sulfuric acid to 0.5-1 g of Ammonium metavanadate. This reagent was invented by the German pharmacologist, Karl Friedrich Mandelin (1854–1906) at the University of Dorpat.

Hyperthermia
Hyperthermia, also known simply as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates. When extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death. Almost half a million deaths are recorded every year from hyperthermia. The most common causes include heat stroke and adverse reactions to drugs. Heat stroke is an body temperature, acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system. Malignant hyperthermia is a rare complication of some types of general anesthesia. Hyperthermia can also be caused by a traumatic brain injury. Hyperthermia di ...

Froehde Reagent
The Froehde reagent is used as a simple spot-test to presumptively identify alkaloids, especially opioids, as well as other compounds. It is composed of a mixture of molybdic acid or a molybdate salt dissolved in hot, concentrated sulfuric acid, which is then dripped onto the substance being tested. The United States Department of Justice method for producing the reagent is the addition of 100 ml of hot, concentrated (95–98%) sulfuric acid to 0.5 g of sodium molybdate or molybdic acid. The Virginia Department of Forensic Science method uses 0.5 g ammonium molybdate per 100 ml H2SO4 (conc.) Unheated sulfuric acid can be used to prepare the reagent in a less dangerous manner, but 2–4 hours must be allowed for the molybdate to dissolve.
