Pituri
Pituri, also known as mingkulpa, is a mixture of leaves and wood ash traditionally chewed as a stimulant (or, after extended use, a depressant) by Aboriginal Australians widely across the continent. Leaves are gathered from any of several species of native tobacco (''Nicotiana'') or from at least one distinct population of the species '' Duboisia hopwoodii''. Various species of ''Acacia'', '' Grevillea'' and ''Eucalyptus'' are burned to produce the ash. The term "pituri" may also refer to the plants from which the leaves are gathered or from which the ash is made. Some authors use the term to refer only to the plant ''Duboisia hopwoodii'' and its leaves and any chewing mixture containing its leaves.Silcock JL, Tischler M, Smith MA"Quantifying the Mulligan River Pituri, ''Duboisia hopwoodii'' ((F.Muell.)

Duboisia Hopwoodii
''Duboisia hopwoodii'' is a shrub native to the arid interior region of Australia. Common names include pituri, pitchuri thornapple or pitcheri. Description The species has an erect habit, usually growing to between 1 and 3 metres in height, with long, narrow leaves. Flowers are white and bell-shaped with violet-striped throats. These appear between June and November in the species' native range followed by purple-black, rounded berries which are 3 to 6 mm in diameter. Like other members of the Solanaceae family such as tobacco, ''D. hopwoodii'' contains nicotine. Pituri Indigenous Australians mix the dried leaves of a small population of ''D. hopwoodii'' growing around the Mulligan River with wood ash to make a variety of pituri, the traditional Aboriginal chewing mixture. ''D. hopwoodii'' plants from this region are high in nicotine and low in nornicotine, whereas those found in some other parts of Australia can have very high levels of nornicotine and are sometimes use ...

Stimulant
Stimulants (also often referred to as psychostimulants or colloquially as uppers) is an overarching term that covers many drugs including those that increase activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription (either legally or illicitly) as performance-enhancing or recreational drugs. Among narcotics, stimulants produce a noticeable crash or '' comedown'' at the end of their effects. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine (Vyvanse), methylphenidate (Ritalin), and amphetamine (Adderall). It was estimated in 2015 that the percentage of the world population that had used cocaine during a year was 0.4%. For the category "amphetamines and prescription stimulants" (with "amphetamines" including amphetamine and methamphetamine) the value was 0.7%, an ...

Nicotine
Nicotine is a natural product, naturally produced alkaloid in the nightshade family of plants (most predominantly in tobacco and ''Duboisia hopwoodii'') and is widely used recreational drug use, recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve drug withdrawal, withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine constitutes approximately 0.6–3.0% of the dry weight of tobacco. Nicotine is also present at Parts-per notation, ppb-concentrations in edible plants in the family Solanaceae, including potatoes, tomatoes, and eggplants, though sources disagree on whether this has any biological significance to human consumers. It functions as an plant defense against herbivory, antiherbivore toxin; consequently, nicotine was widely used as an insectic ...

Nicotiana Rosulata
''Nicotiana rustica'' is a plant in the family Solanaceae, native to Western Australia, South Australia and the Northern Territory. ''N. rosulata'' was first described in 1899 as ''Nicotiana suaveolens'' var.

Nornicotine
Nornicotine is an alkaloid found in various plants including ''Nicotiana'', the tobacco plant. It is chemically similar to nicotine, but does not contain a methyl group. It is a precursor to the carcinogen ''N''-nitrosonornicotine that is produced during the curing and processing of tobacco. Nornicotine can react in human saliva to form N-nitrosonornicotine, a known type 1 carcinogen. Synthesis There are several routes for the synthesis of nornicotine. One route is the demethylation of nicotine, which can be accomplished by reaction with silver oxide. \mathrm Another route is the partial reduction of 3-myosmine, which can be accomplished by standard catalytic hydrogenation conditions using palladium as a catalyst or with sodium borohydride.. This reaction gives the racemic In chemistry, a racemic mixture, or racemate (), is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt.

Alice Springs
Alice Springs ( aer, Mparntwe) is the third-largest town in the Northern Territory of Australia. Known as Stuart until 31 August 1933, the name Alice Springs was given by surveyor William Whitfield Mills after Alice, Lady Todd (''née'' Alice Gillam Bell), wife of the telegraph pioneer Sir Charles Todd. Known colloquially as 'The Alice' or simply 'Alice', the town is situated roughly in Australia's geographic centre. It is nearly equidistant from Adelaide and Darwin. The area is also known locally as Mparntwe to its original inhabitants, the Arrernte, who have lived in the Central Australian desert in and around what is now Alice Springs for tens of thousands of years. Alice Springs had an urban population of 26,534 Estimated resident population, 30 June 2018. in June 2018, having declined an average of 1.16% per year the preceding five years.
