Methamphetamine, also known as meth, crystal meth, or ice, is the second most abused illicit drug in the world (cannabis is first), with 15-16 million regular users. The United States saw a rapid growth in methamphetamine addiction in the early 2000s. It was during that epidemic that PROMETAT burst onto the public scene through an aggressive marketing campaign.
Since its introduction, the PROMETAT protocol has been widely used in specialized private clinics in the U.S. as a treatment for methamphetamine addiction without going through the normal drug approval process. Normally, introducing a new medication requires approval by the U.S. Food and Drug Administration, including tests of product safety and a clinical trial to make sure the treatment produces the predicted effects. A loophole in this regulatory system allows a combination of previously approved medications to be marketed without review, whether or not the individual medications were originally approved as a treatment for the condition the new protocol targets. The manufacturer of PROMETAT, Hythiam, was therefore able to market and sell the new protocol with no federal review or clinical trial evidence.
Private patients reportedly pay $12,000 to $15,000 for one month of treatment.
Hythiam used some of its profits to fund the clinical trials long called for by the scientific community, including this one, designed and led by Dr. Walter Ling, a respected U.S. scientist and expert on methamphetamine addiction. Ling and his fellow researchers found that the group of participants given the PROMETAT treatment did not have better outcomes than those given placebo in terms of reducing methamphetamine use, retention in treatment, or reducing methamphetamine cravings.

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
