In a recent report, HS-SPME was used for the extraction of amphetamines from human hair (142). Human hair analysis is gaining interest in the analysis of drugs of abuse, since it offers attractive features easy and unlimited sampling, and as the... 

The nucleus accumbens is part of the limbic system. It receives dopaminergic input through the mesolimbic system that originates from cell bodies in the ventral segmental area (A 10 cell group). This mesolimbic dopaminergic pathway is part of the reward pathways. Drugs of abuse (cocaine, amphetamine, opiates or nicotine) have been shown to increase the level of dopamine release in these neurons. 

Uni 1ke other drugs of abuse, the diagnosis of PCP intoxication is often difficult because of the wide spectrum of clinical findings that occurs with this drug. PCP toxicity sometimes can be mistaken for delirium tremens, acute psychiatric illness, sedative/ hypnotic overdosage, amphetamine intoxication, or sedative/ hypnotic withdrawal syndromes.

Dopamine activity can be enhanced in one of four main ways. Medications can stimulate dopaminergic nerve cells to release dopamine into the synapse. This is the way that stimulants such as methylphenidate (Ritalin), dextroamphetamine (Dexe-drine), and dextroamphetamine/amphetamine (Adderall) work. In addition, certain drugs of abuse, notably cocaine and methamphetamine, act in part in this way. Providing more of the raw material that nerve cells use to manufacture dopamine can also increase dopamine activity. This is the approach that neurologists use when they prescribe L-DOPA (Sinemet) to patients with Parkinson s disease. Nerve cells convert L-DOPA into dopamine. L-DOPA otherwise has little place in the treatment of psychiatric disorders. Dopamine activity can also be increased by medications that directly stimulate dopamine receptors. Bromocriptine, another medication used to...

Certain medicines may not be imported under the personal importation provisions, including drugs of abuse, such as narcotics, amphetamines and psychotropic substances, and anabolic substances, androgenic steroids and treatments for alcohol and drug addiction. There are also controls over certain other medicines including erythropoietin, growth hormones and gonadotrophins. 

Drug abuse and dependence Studies in healthy volunteers, subjects with a history of multiple drug abuse, and depressed patients showed some increase in motor activity and agitation/excitement. In individuals experienced with drugs of abuse, a single dose of 400 mg bupropion produced mild amphetamine-like activity as compared with placebo. 

Doping substances include most of the drugs already discussed in the previous sections (e.g., drugs of abuse like amphetamines, cocaine, opiates pharmaceutical drugs like diuretics, beta-blockers, etc.) and, in most cases, the described methods may be extended to doping control applications.
