Methamphetamine use has spread in many European countries and the United States. The current review provides a summary and critical analysis of research on cognitive deficits associated with methamphetamine, also known as "crystal meth." The literature search performed for this review led us to the hypothesis that methamphetamine use is associated with persistent changes in brain metabolism that result in various impairments, such as deficits in memory, attention, and concentration. The dopaminergic system in particular seems to be affected...

BACKGROUND: Dual substance dependence and psychiatric and psychological morbidities are overrepresented in prison populations and associated with reoffending. In the context of an increasing prison population in Australia, investigating the needs of vulnerable people in prison with a dual diagnosis can help inform in-prison screening and treatment and improve prison and community service integration and continuation of care. In this study we quantified psychiatric well-being in a sample of people in prison with a history of injecting drug use in Victoria, Australia, and identified factors associated with this outcome...

In this contribution, completely different from traditional probes based on molecular host-guest interaction, crystal level interaction was proposed as an ultrasensitive design strategy for molecule detection. In such strategy, crystal-guest interaction triggered rapid crystal disaggregation to gain great signal change, far more efficient than molecule scale coupling. Highly ordered pyrene methanol (PM) crystal was self-assembled with hydrogen bond chain and π-π stacking force. Its {011} surface can be destabilized by methamphetamine hydrochlorate (MA, heavily used illicit drug) selectively and efficiently...

Methods to quickly purify methamphetamine hydrochloride from the cutting agent dimethyl sulfone for subsequent identification of confiscated crystalline samples using infrared absorption spectroscopy were compared and evaluated. Although sequential solvation and reprecipitation methods were simple, spectral contamination from dimethyl sulfone was inevitable and might affect the interpretation of the spectra. In addition, methamphetamine hydrochloride and dimethyl sulfone could form a solid solution because of solvation of both crystals into a single solution layer...

Methamphetamine hydrochloride, colloquially referred to as "crystal meth," is a potent psychoactive amphetamine derivate. Methamphetamine produces stimulant effects in the user including increased energy and alertness as well as inducing intense euphoric symptoms and suppressing appetite through its dopaminergic, serotonergic, and adrenergic actions. Use of methamphetamine can adversely affect cardiovascular, neurological, and gastrointestinal physiology leading to significant morbidity. We present a rare case of paralytic ileus secondary to methamphetamine abuse which has only once before been described in the literature...

Despite high rates of smoking (70-90%) and the severely negative impact of smoking on physical and mental health, only 12% of individuals receiving stimulant-use disorder treatment also receive smoking-cessation treatment. The aim of this investigation was to examine the effect of a contingency management (CM) intervention targeting methamphetamine (MA) use on cigarette smoking. Sixty-one adults with MA-use disorders who were smokers were assigned to CM or standard psychosocial treatment. Rates of smoking-negative breath samples (carbon monoxide <3 ppm) were compared between the two groups while controlling for baseline carbon monoxide level, marijuana use, MA use, and time...

The crystalline form of methamphetamine, commonly known as crystal meth (crystal methamphetamine) or ICE, is a highly-addictive and powerful stimulant. Users of crystal meth often require emergency care, and are associated with a substantial burden of care by emergency care providers. The aim of the present qualitative study was to explore health professionals' experiences of providing care for patients affected by ICE who presented to the emergency department (ED). Nine semistructured interviews were conducted...

Ecstasy (MDMA) has regained popularity in powder and crystalline form, known as Molly. However, it is unknown whether all Molly users are aware that Molly is ecstasy. A total of 1045 nightclub/festival-attending adults in New York City were surveyed about ecstasy/MDMA/Molly use in 2016. Users were asked if they agreed that "Molly is (or is supposed to be) ecstasy/MDMA." Of the 43.5% reporting lifetime use, 84.6% agreed that Molly is ecstasy, 9.5% disagreed, and 5.9% reported not knowing that Molly is ecstasy...

Human immunodeficiency (HIV) infection results in neurocognitive deficits in about one half of infected individuals. Despite systemic effectiveness, restricted antiretroviral penetration across the blood-brain barrier (BBB) is a major limitation in fighting CNS-localized infection. Drug abuse exacerbates HIV-induced cognitive and pathologic CNS changes. This study's purpose was to investigate the effects of the HIV-1 protein, Tat, and methamphetamine on factors affecting drug penetration across an in vitro BBB model...

PURPOSE: Injection drug use is prevalent among street-involved youth, but patterns of cessation are poorly described. We identified drug use patterns preceding injection cessation among street-involved youth. METHODS: From September 2005 to May 2015, we collected data from the At-Risk Youth Study, a prospective cohort of street-involved youth in Vancouver, Canada, and limited the sample to actively injecting youth. The primary outcome was cessation of injecting self-reported at semiannual follow-up visits...

Recreational drug use (RDU) has been reported to be disproportionately higher in men who have sex with men (MSM) when compared to their heterosexual counterparts. To identify RDU, links to risky sexual practices and infections for MSM attending three sexual health clinics across Manchester, United Kingdom, a retrospective case note review was conducted using a random powered sample of service users attending three sites during 2014. Three hundred and fifty-seven case notes were reviewed across three sites. Eighteen per cent of service users reported any type of RDU...

Methamphetamine (also known as meth and crystal meth) is a highly psychoactive synthetic amphetamine type stimulant, which falls under the German Federal Narcotics Law. The substance is similar to other stimulants but has distinct features with respect to psychoactive effects, clinical symptoms, user characteristics and short and long-term consequences including substance-induced problems and comorbidities. The consumption and misuse of crystal meth is still limited to certain regions in Germany; however, the substance causes significant clinical and public health concerns in the affected regions and beyond due to the associated high potential for misuse and dependence, neurotoxic and neurodegenerative effects as well as many other severe health risks...

BACKGROUND: Supervised injection services (SIS) have been shown to reduce the public- and individual-level harms associated with injection drug use. While SIS feasibility research has been conducted in large urban centres, little is known about the acceptability of these services among people who inject drugs (PWID) in mid-sized cities. We assessed the prevalence and correlates of willingness to use SIS as well as design and operational preferences among PWID in London, Canada. METHODS: Between March and April 2016, peer research associates administered a cross-sectional survey to PWID in London...

We measured the affinity of five molecular container compounds (calabadions 1 and 2, CB[7], sulfocalix[4]arene, and HP-β-CD) toward seven drugs of abuse in homogenous aqueous solution at physiological pH by various methods ((1) H NMR, UV/Vis, isothermal titration calorimetry [ITC]) and found binding constants (Ka values) spanning from <10(2) to >10(8)  m(-1) . We also report X-ray crystal structures of CB[7]⋅methamphetamine and 1⋅methamphetamine. We found that 2, but not CB[7], was able to ameliorate the hyperlocomotive activity of rats treated with methamphetamine...

Over the past several years, the number of first-time users of methamphetamine considerably increased within the Free State of Saxony. This number also, and especially, includes women of child-bearing age and young mothers. A supportive intervention aimed at reducing the effects of drug abuse should begin in a timely way - during pregnancy at latest, but better before it. To develop an optimal care protocol for both the mother and her child, more knowledge regarding the personal conditions of the women as well as the specific features of later child development after prenatal methamphetamine exposure (PME) is vital...

Crystal methamphetamine (MA) is a potent psycho-stimulant that is increasingly used worldwide. It is highly addictive, is often made in clandestine laboratories, and can cause serious health issues in adults. Health professionals caring for women in the perinatal period must counsel women about the health risks to infants if they are exposed to MA in breast milk. Most guidelines recommend that women who have current or recent MA use do not breastfeed. This article explores approaches to breastfeeding advice in the context of MA use...
