A team led by Dr. Benedikt Fischer, a researcher funded by the Canadian Institutes of Health Research (CIHR) and based at the Centre for Addictions Research (CARBC) at the University of Victoria, published its findings in the November 21, 2006 issue of the Canadian Medical Association Journal.
Opioids are commonly prescribed as pain-killers (analgesics). Prescription opioids that are commonly prescribed in Canada include Oxycontin, morphine, Demerol, Percodan and Tylenol 3 or 4.
"Our study suggests that heroin use has become an increasingly marginal form of drug use among illicit opioid users in Canada, especially outside Vancouver and Montreal," says Dr. Fischer.
Heroin use was substantially prevalent only in Vancouver and Montreal. It was de facto absent in smaller cities like Edmonton, Quebec City or Fredericton. And, in all study sites, there was a significant decline of heroin use among participants between 2001 and 2005.
Dr. Fischer also highlights that in a large number of cases prescription opioids used by street drug users originate from the medical system and not from illicit production and distribution.
The secondary and reduced relevance of heroin compared to prescription opioids among illicit opioid users has implications for drug control policy and treatment programs, which primarily focus on heroin abuse and dependence.
"Our drug control policies ought to be targeting prescription opioid abuse more effectively," says Dr. Fischer. "But we also need to ensure we do not compromise legitimate access to and uses of prescription opioids."
Dr. Rémi Quirion, based in Montreal and Scientific Director of the CIHR Institute of Neurosciences, Mental Health and Addiction says, "although there have been reports on the increased levels of prescription opioid abuse in Canada and other jurisdictions, there has until now not been a systematic documentation of usage patterns among street drug users."
"This study, conducted by Dr. Fischer and his team provides us with the scientific evidence needed to improve public policy and treatment programs. Such research is key to ultimately improving the health of Canadians," adds. Dr. Quirion.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
