The paste form once dried becomes a powder. The crystal, the tablet and the beads inside the capsule forms need to be pounded until they become fine powder. Street amphetamines are almost always already in powder from, so no further prep is required. Snorting – Also called insufflation or intranasal administration, this method is never used in therapeutic settings and requires the drug to be in fine powder form.This means that the powder or paste is mixed with liquid or put inside a capsule so it can be swallowed. The powder and/or paste forms of the drug may be taken orally by parachuting. The oral route is also generally the safest. This method takes the longest for the drug to take effect, from 15-60 minutes, because it has to go thru the metabolic process of the body. Oral – This is the only method of administration used in therapeutic settings but is also a common method for recreational purposes and makes use of the drug in its tablet/capsule form.The methods of administration depend upon which form of the drug is being used, as follows: When it dries, it becomes the powder form and can then be rubbed on the gums, snorted or mixed into drinks and taken orally. It is administered by rubbing on the gums. The base/paste form is sometimes called “wet speed” and is popular in Europe. At present, amphetamines are prescribed for the treatment of ADHD, narcolepsy, obesity and depression.Īmphetamines are available in tablet/capsule, base/paste, sheet-like crystal, powder/speed and liquid forms. Stimulants were first used medically to treat respiratory problems like asthma because they act as bronchodilators. It also elevates heart rate, blood pressure and respiration. Stimulants increase a person’s attention, alertness and energy. It is what they call in the streets an “upper”. Some examples of drugs that fall under this class include:Īmphetamine is a stimulant. Drugs under this class are considered dangerous and require a prescription. Screening Cut-Off GC/MS Cut-Off (Confirmatory) Approximate Detection Time Urine Drug Test 1000 ng/ml (AMP) 500 ng/ml (AMP) From 2-5 hrs after use up to 2-4 days (AMP) Blood Test 300 ng/ml (AMP300) 500 ng/ml (AMP300) From 2-5 hrs after use up to 2-4 days (AMP300) Saliva Drug Test 1000 ng/ml (AMP) 500 ng/ml (AMP) From 5-10 min after use up to 1-3 days (AMP) Nail Drug Test 500 pg/mg 200 pg/mg From 3-6 months after use Hair Follicle Drug Test 300-500 pg/mg 200-500 pg/mg From 5-7 days after use up to 90 days6Īmphetamines are classified under Schedule II of the Controlled Substances Act which lists drugs, substances or chemicals that have a high potential for abuse, the usage of which can potentially lead to severe physical and psychological dependence but with accepted medical uses. The gas chromatography mass spectrometry GC/MS confirmatory tests on the other hand look for specific metabolites that identify and quantify a specific drug.
The immunoassay tests done during initial screening are intended to detect a wide range of compounds that are chemically similar and that react with antibodies contained in the reagents. There are also different cut-off levels for screening and gas chromatography mass spectrometry GC/MS confirmatory testing because they use different testing methodologies.ĭifferent testing methods mean different cut-off levels. Just like any drug, screening for amphetamines is guided by clear cut-off levels that vary depending upon the type of sample used.
It does not take very long to develop an addiction to the drug. It provides a quick and intense high but it is considered “low tolerance” which means that more of the drug is needed to achieve the same effect. While helpful when used properly under strict medical supervision, amphetamines are highly addictive and cause many unpleasant side effects including aggressive over confident behavior, agitation and disorientation. Illegally produced amphetamine is sold for its stimulant properties. It is also used to improve brain development.
Today, amphetamines are used legally as a prescription drug for the treatment of narcolepsy, ADHD, obesity, chronic fatigue syndrome and depression. It is a powerful psycho-stimulant that affects key neurotransmitters in the brain (dopamine, norepinephrine and serotonin) giving a person an intense euphoric feeling. Amphetamines are a synthetic, mood-altering drug that was first discovered in the late 1800's and later used medically to treat asthmatic patients.
