Background: Amphetamine and methamphetamine are popular drugs of abuse worldwide and are important components of drug monitoring programs. Windows of detection for amphetamine and methamphetamine in oral fluid after high doses have not been investigated. Repeated high-dose ingestions are likely to cause positive samples for extended periods. Common routes of administration of amphetamine/methamphetamine in Norway are oral intake or injection. The aim of this study was to investigate windows of detection for amphetamine and methamphetamine in oral fluid from drug addicts under sustained abstinence during detoxification.
Methods: Twenty-five patients admitted to a closed detoxification unit were included in this study. Oral fluid samples were collected daily in the morning and evening, and urine every morning for 10 days. A blood sample was drawn during the first 5 days after admission if the patient consented. Oral fluid results were compared with urine results to determine whether a new ingestion occurred. Oral fluid was collected with the Intercept oral fluid collection device. In-house cutoff concentrations for amphetamine and methamphetamine were 6.8 and 7.5 mcg/L, respectively, in oral fluid, and 135 and 149 mcg/L, respectively, in urine.
Results: Amphetamines were detected in 11 oral fluid, 5 urine, and 2 blood specimens from 25 patients. Patients self-reported amphetamines intake of up to 0.5-2 g daily. Windows of detection for amphetamine and methamphetamine in oral fluid were up to 8 days, longer than in urine at the applied cutoff values.
Conclusions: These data confirm that oral fluid is a viable alternative to urine for monitoring amphetamine abuse, and that these substances might be detected in oral fluid for at least 1 week after ingestion of high doses. Such long detection times were, as far as we are aware, never reported previously for oral fluid amphetamines.
Aim: To describe health service contact in the two years prior to a first hospital admission with amphetamine-related psychosis, and to identify possible opportunities for early intervention.
Method: Routine health data collections were used to identify 6130 persons aged 16-65 who had a first hospital admission with amphetamine-related psychosis in New South Wales (NSW), Australia, between 2005 and 2016. Health service contacts in the two years prior to first admission were identified, using public hospital, emergency department and community mental health data. Prior care was compared to 41,444 people with first psychosis admissions without amphetamine diagnoses.
Results: Two thirds of people with amphetamine-related psychosis had health service contact in the two years prior to their first psychosis admission. Of these, 45% had ED contacts and 30% had prior general hospital admissions. The likelihood of contact escalated throughout the two years prior to admission. Prior substance-related conditions, infectious diseases, injuries and accidents were common. Compared to other first psychosis admissions, people with amphetamine-related psychoses were less likely to have prior specialised mental health care (OR 0.84, 95% CI 0.78, 0.89) and more likely to have prior general health care (OR 1.40, 95% CI 1.29, 1.51).
Conclusion: Emergency departments and units treating people with infectious diseases or injuries should consider strategies to detect amphetamine and other substance use. Early detection and referral to specialist mental health or drug and alcohol care may prevent some amphetamine-related psychoses.
In the Auckland Region, wastewater analysis indicates more methamphetamine is consumed than MDMA [4]. The plasma amphetamines analysis uses mass spectrometry to detect three drugs in plasma: Amphetamine, Methamphetamine and MDMA. This plasma amphetamine assay is not intended to detect novel psychoactive substances (e.g. cathinone) or other amphetamines such as MDEA, MDA, PMA, ephedrine and phentermine.
I am running windows 11 on a laptop. There is an option in control panel to make the computer go to sleep when the lid/display is closed. This also makes the computer wake from sleep when opening the lid. However, I want my laptop to not go to sleep when the lid is shut, but wake if it is currently sleeping and the laptop lid is opened. Is this possible? If so, how would I do this?
Methamphetamine is a stimulant drug. A form of the drug known as methamphetamine hydrochloride, marketed as Desoxyn, is a Food and Drug Administration (FDA)-controlled substance used to treat attention deficit hyperactivity disorder (ADHD) and obesity.
Users often smoke or snort crystal meth. Smoking the drug can quickly elevate levels of methamphetamine in the brain. This gives users a rapid, intense high, making crystal meth both more addictive and potentially more harmful than other forms of methamphetamine.
Use of crystal meth in the United States exploded in the early 1990s. Between 1994 and 2004, methamphetamine use rose from just under two percent of the U.S. adult population to approximately five percent.
While Adderall and Ritalin have some chemical properties in common with methamphetamine, they are generally considered safer when taken at prescribed doses and under the supervision of a medical practitioner. Misuse of the drugs, however, can lead to addiction.
"Doping" is as old as sporting events themselves and can be defined as the attempted use of a prohibited substance or prohibited method with the intent of improving athletic performance. As early as 800 B.C., ancient Greek athletes and Roman gladiators ingested a combination of herbs, plants, and mushrooms to gain a competitive edge and mask pain (1). With the debut of the modern Olympic Games in 1896, the practice of doping rapidly spread and different classes of compounds were used depending on the sporting event. For instance, athletes took stimulants (cocaine and amphetamines) to improve performance in speed and endurance sports, whereas they used anabolic steroids to promote muscle mass in sports requiring strength and power.
GC-MS detects target compounds by comparing the retention time and relative intensities of ion fragments in unknown samples to those obtained for reference compounds. The collected data are reduced to dedicated windows consisting of selected time slices and mass-to-charge (m/z) ions corresponding to the expected retention times and mass spectral fragments for each target compound. Interfering peaks and background noise can complicate GC-MS data reading because screening methods are designed to detect entire classes of compounds and are not optimized for individual compounds. Furthermore, a single ion fragment may not be unique and might be shared by compounds. These issues limit the use of automated software programs for GC-MS data reading and require that experienced data readers carefully evaluate all data. In contrast, LC-MS/MS and GC-MS/MS measure the relative abundance of precursor/product ion pairs (transitions). Because the likelihood of a target compound and an interfering substance having the same precursor/product ion pairs is relatively small, the data usually are easier to interpret compared to GC-MS data and can be more easily evaluated by computer software.
GC-MS screening data for six stimulants are shown in Figure 2. The retention times of reference compounds are indicated in each window by a vertical line and the relative abundance of each ion is displayed on the y-axis. Although some of the windows have considerable background signals, the urine sample appears negative for all of the stimulants except amphetamine. A peak appears at the appropriate retention time for all three m/z ions in the amphetamine windows, so this sample would be considered screen positive and would undergo confirmation testing.
For confirmation testing an additional aliquot of urine from the 'A' bottle would be analyzed separately using a testing method optimized to detect amphetamine. Ion chromatograms and mass spectra of the trifluoroacetyl derivative of amphetamine are shown in Figure 3. The negative urine (panel A) does not contain ions at the retention time of the positive urine (panel B). In contrast, the screen positive sample (panel C) contains a peak for each of the m/z ions at the same retention time as the positive control in panel B. Relative abundance of diagnostic ions in the screen positive sample (m/z 118 and 91 as a percentage of m/z 140) match those obtained for the positive urine sample and all diagnostic ions with a relative abundance of >10% that are present in the positive control are also present in the screen positive sample based on full scan mass spectra data (right panels), confirming the presence of amphetamine. The confirmation data would be reviewed by two certifying scientists before being reported as an adverse analytical finding for amphetamine and must also fulfill all identification criteria in the WADA technical document (7). If the client requests 'B' bottle testing for the substance identified in the 'A' bottle, the athlete and/or his or her representative has the right to observe the entire testing process.
Understanding how detection windows vary and factor into the specimen type is crucial. The amount of substance consumed, absorption into the blood stream, distribution to organs and tissues, metabolism to inactive compounds, and elimination from the body are all functions of detection window. While blood, breath and oral fluid can often detect new substance use within minutes of consumption, sweat may require multiple days of use, and hair can take up to two weeks before substance use is detectable. For example:
I want to make it clear to you that if your work requires heavy use of something "very-windows-dependent", like SQL Server - or old MSMQ - you might have a harder time to completely switch over to MacOS for obvious reasons. There's simply no good tools for it yet for MacOS (or Linux for that matter). And on the other hand - the switch might be easier if you use tools like Azure, ElasticSearch, Redis etc that either requires heavy use of just a web browser as the primary client to interact with, or cross-platform CLI tools, or anything that runs just fine in docker.
