What is it?
Amphetamines are very addictive stimulants that accelerate functions in the brain and body. They come in pills or tablets. Prescription diet pills also fall into this category of drugs.
Speed is an off-white or pinkish powder and can sometimes look like small crystals. However, there are other types of speed:
it ia also Known as whizz, sulph, base, speed, uppers, dexies, bennies, hearts, and truck drivers.
It is categorised as a stimulant.
How it's taken
Amphetamines are swallowed, smoked, snorted, or injected.
Speed is either dabbed onto the gums, or is snorted in lines (like cocaine powder). Sometimes it's rolled up in a cigarette paper and swallowed, this is called a 'speedbomb'. It can also be injected or mixed into drinks.
The effects of speed kick in within half an hour of swallowing. If you snort or inject speed it will kick in quicker - the effects can last for up to six hours.
For 3 to 4 hours users feel animated, over-confident, and full of energy. Appetite and ability to sleep are adversely affected. Speed use can lead to agitation, panics or even a psychotic episode.
No matter how a person takes amphetamines, these drugs hit with a fast high, making the user feel powerful, alert, and energized.
These "uppers" pump up heart rate, breathing, and blood pressure, and can also cause sweating, shaking, headaches, sleeplessness, and blurred vision.
Prolonged use may cause hallucinations and intense paranoia.
Even after users stop taking amphetamines, they may still have problems such as aggression, anxiety, and strong cravings for the drugs.
Short term: Some users may feel tense and anxious while using and afterwards many feel very tired and depressed. Depending on how much you've taken, it can be difficult to relax or sleep. The 'comedown', which can last a number of days, can make users feel really lethargic and down, and you can develop difficulty concentrating and with learning. The drug can cause sudden death from heart attack or stroke.
Long term: Frequent high doses can cause panic, hallucination and weight loss. Heavy long-term use places strain on the heart and can cause mental illness. Amphetamines are addictive. Mixing speed with anti-depressants or alcohol has been known to kill. Injecting 'speed', and sharing injecting equipment, runs the risk of the injector catching or spreading a virus such as HIV or hepatitis C. There is also the risk that veins may be damaged and that an abscess or a blood clot will develop.
Amphetamines are a Class B drug meaning it's illegal to have, give away or sell. Possession of amphetamines can get you up to five years in jail or an unlimited fine or both. Supplying amphetamines to someone else, including friends, can get you up to 14 years in prison or an unlimited fine or both.
When amphetamines are prepared for injection they become a Class A and can get you tougher sentencing if you're caught possessing or selling. Possession of a Class A can get you up to seven years in jail or an unlimited fine or both. Supplying a Class A to someone else, including your friends, could lead to life imprisonment or an unlimited fine or both.

The first national study of drug use through analysis of sewage has found that, while Australians are big users of illegal stimulants compared with Europeans, their alcohol intake is "relatively low".

The book, The Total Rush, reveals the astonishing and largely untold story of the Third Reich's relationship with drugs, including cocaine, heroin, morphine and, above all, methamphetamines (aka crystal meth), and of their effect not only on Hitler's final days - the Fuhrer, by Ohler's account, was an absolute junkie with ruined veins by the time he retreated to the last of his bunkers - but on the Wehrmacht's successful invasion of France in 1940.
If you thought Ritalin was invented in the early 00s - when every hyperactive American kid popped a few mills with his Cap'n Crunch and zipped off to 4th grade homeroom - you wouldn't be alone. But methylphenidate has been around as a treatment for hyperactivity since at least the 60s. Then, as now, doctors were quick to give kids this legal meth when deeper emotional issues were desperately seeking diagnosis.
Amber was out of control. She knew she should stop. But her intense lows made her feel like she was being slowly crushed by a truck. And the promise of her highs was so great that it didn't matter how many times she'd told herself she was done for good. Sitting at her dorm-room desk yet again, she placed three round pills on a fresh piece of white computer paper. She used the flat bottom of a lighter to smash them into a candy-blue powder.
Turkish authorities this weekend seized 11 million Captagon pills - the amphetamine drug that is used in huge amounts by Isis fighters to keep them alert and full of energy.

Fading fast at 11 p.m., Elizabeth texted her dealer and waited just 30 minutes for him to reach her New York apartment. She handed him a wad of twenties and fifties, received a tattered envelope of pills, and returned to her computer.

"I love working. Amphetamine use is about working harder and keeping the tempo up", a painter explained. Several of his colleagues also used the drug. They snorted amphetamine in the morning before work and during their lunch break at noon, to be effective and work as quickly as possible.
Most of my life I've been in some sort of addiction. From twelve, I used to steal money from my mother. I left school, got involved in crime, started sniffing glue, and then doing amphetamines. I stopped doing amphetamines for a while, settled down with a girlfriend, had my first child with her at 21. My girlfriend became pregnant again a year-and-a-half later, by then I'd started doing amphetamines again; slowly my relationship was breaking down, it came to an end and I just started hitting the clubs and drinking.
Sheri is a junior in college. In the mornings, she has class, and in the afternoons, she has work. Sheri has ADD, and without her medication, has a hard time getting out of bed. Her medication is Adderall, but Sheri doesn't have health insurance and can't afford the $300 a month for the prescription. But Sheri is lucky, because she knows Dan, who sells Adderall to college students for $5 to $15. Dan does good business, as Adderall is America's favourite amphetamine, especially among college students trying to maintain focus.
As Syria sinks ever deeper into civil war, evidence is starting to emerge that a brutal and bloody conflict is now also being fuelled by both the export and consumption of rapidly increasing quantities of illegal drugs.
Separate investigations have found that the growing trade in Syrian-made Captagon - an amphetamine widely consumed in the Middle East but almost unknown elsewhere - generated revenues of millions of dollars.
John Hunt, the leader of the 1953 British Mount Everest expedition, was an exceptional strategist. When the Swiss attempts to climb Everest in 1952 failed, he used their experience to design a new plan for the British team.
One key change was the route to the top; while the Swiss climbed the Geneva Spur, the British headed for the Lhotse Face. A longer climb overall, the Lhotse route is stepped, so intermediate camps can be established.

It was there that her son, Richard, visited a doctor and received prescriptions for Adderall, an amphetamine-based medication for attention deficit hyperactivity disorder. It was in the parking lot that she insisted that he did not have ADHD, and that he was getting dangerously addicted to the medication.
The death of Claire Squires, a fit and healthy 30-year-old, 1 mile from the end of the London marathon last year, caught the country's imagination.
On Wednesday a coroner ruled that the most likely cause off her death was a single dose of Jack3d, a performance-enhancing supplement that at the time was legal to buy, possess and use. That supplement, with its amphetamine-type effects, was to be banned four months later by the Regulatory Agency.
He steered into the high school parking lot, and clicked off the ignition. On the passenger seat, a rumpled SAT practice book whose owner had been told since fourth grade he was headed to the Ivy League. Pencils up in 20 minutes.
The boy exhaled. Before opening the car door, he recalled recently, he twisted open a capsule of orange powder and arranged it in a neat line on the armrest. He leaned over, closed one nostril and snorted it.
Amphetamine didn't cure anything, but it did make you feel better. Chemist Gordon Alles faced this paradox after patenting his discovery in 1932.
Alles was trying to improve on the blockbuster asthma treatment ephedrine. He didn't know his drug had been first synthesized in 1887 by Romanian Lazar Edeleanu. For 40 years chemists considered it valueless, but Alles was to prove them wrong, discovering the first psychoactive prescription drug.
