Clear public health message on cannabis needed
Smoking cannabis, like smoking tobacco, can be a major public health hazard but, at present, there is no clear public health message about cannabis, argue researchers in this week's BMJ. (2003-05-01)

Cannabis smoking could be responsible for up to 30,000 deaths in the UK, estimate doctors from Imperial College London and St Mary's Hospital. (2003-05-01)

What future for cannabis?
The potential therapeutic effects of cannabis are outlined in a review in the May issue of The Lancet Neurology. The review is published in anticipation of results from randomised trials expected later this year investigating possible benefits of the drug for people with multiple sclerosis. The first cannabis-based medicines are currently being considered for license. (2003-04-16)

Sobering data on student DWI habits
Dr. Edward Adlaf and colleagues present data from the 2001 Ontario Student Drug Use Survey, which indicate that 31.9% of 1846 Ontario students surveyed admitted to being a passenger in a car driven by a drunk driver in 2001. (2003-03-03)

Early marijuana use increases risk of drug and alcohol problems later in life
A study of Australian twins has found that the age a person begins to smoke marijuana has a significant influence on whether they will develop drug and alcohol problems later in life. (2003-01-21)

Cannabis increases risk of depression and schizophrenia
Frequent cannabis use increases the risk of developing depression and schizophrenia in later life, according to three studies in this week's BMJ. (2002-11-21)

How the body copes with fear
Using the model of fear conditioning in mice, researchers from the Max Planck Institute of Psychiatry together with colleagues from Naples demonstrate that the cannabinoid receptor is important in erasing fear behavior. In mouse mutants lacking the cannabinoid receptor CB1, erasure of fear behavior evoked by an aversive acoustic sound was considerably lessened compared to normal control mice. Possible applications in the treatments of phobias, posttraumatic stress disorders, and certain forms of chronic pain. (2002-08-01)

The Lancet Oncology (TLO) and the Lancet Infectious Diseases (TLID)
This month's Oncology Leading Edge editorial discusses the difference between perception of risk and the actual risk by drawing upon two recent examples: breast cancer and the pill, and cannabis smoking and cancer risk. (2002-07-31)

Marijuana receptor gene abnormality in schizophrenia
Researchers from Japan show that the gene encoding the marijuana (also known as cannabinoid) receptor have triplet repeats that are different in schizophrenic patients when compared to healthy controls. This was particularly evident in a subtype of the disorder called hebephrenic schizophrenia. These data support the concept that a disruption of the body's own cannabinoid system (which is activated by marijuana) can be involved in schizophrenia. (2002-07-01)

Jury's still out on use of marijuana derivative for MS
Anecdotal claims of the benefits of marijuana for people with multiple sclerosis (MS) have been around for years, but the few studies on the topic have been small and inconclusive. A new study suggests that marijuana derivatives do not improve MS symptoms, but researchers say more studies need to be done before conclusions can be reached. (2002-05-13)

Marijuana use linked to hallucinogen use
Young marijuana smokers are substantially more likely than non-smokers to be presented with the opportunity to try hallucinogens. Once the opportunity for hallucinogen use occurs, marijuana smokers are more likely than non-smokers to actually try it. (2002-04-10)

DEA approves UC center for medicinal cannabis studies
The UC's Center for Medicinal Cannabis Research,(CMCR),has received DEA approval to begin two clinical studies on the possible efficacy of cannabis in the treatment of two severe medical disorders. (2001-11-30)

Cannabis on trial
The potential benefits of smoked cannabis as a pain-reliever are about to be examined by researchers at the McGill Pain Centre. Based at the McGill University Health Centre, the study will be the world's first peer-reviewed clinical trial examining the effects of smoked cannabis in a non-HIV population and is being supported by the Canadian Institutes for Health Research (CIHR) and Health Canada. (2001-07-26)

Cannabinoids give no more pain relief than codeine tablets
Cannabinoids (the active substances in cannabis) are no more effective than conventional analgesics in controlling pain and have undesirable side effects, concludes a study in this week's BMJ. Their introduction into mainstream clinical practice for pain management is therefore undesirable, report the authors. (2001-07-06)

Cannabinoids may prevent chemotherapy related sickness
Cannabinoids (the active substances in cannabis) are more effective than conventional drugs at preventing nausea and vomiting in patients undergoing chemotherapy, and patients prefer them, finds a study in this week's BMJ. However, potentially serious side effects, even when taken short term, are likely to limit their widespread use, conclude the authors. (2001-07-06)

First medicinal cannabis studies approved by research center
The Center for Medicinal Cannabis Research (CMCR), a University of California-based center funded by the State of California, announces the approval of its first proposals for the study of cannabis as a treatment for specific medical conditions. (2001-02-21)

Drug study: price is more effective than punishment
New research at Adelaide University in Australia has found that the cost of marijuana -- not the legal punishment for marijuana offences -- is the real key to reducing the amount of the drug used. (2000-11-12)

Center for Medicinal Cannabis Research established at University of California
A statewide, state-funded initiative to rigorously study the safety and efficacy of medicinal cannabis to treat certain diseases is being established at the University of California. The Center for Medicinal Cannabis Research (CMCR), headquartered at UCSD,will be a collaboration between UCSD and UCSF, two of the UC system's leading biomedical research campuses. (2000-08-28)

Marijuana Not A Factor In Driving Accidents
The safety hazards of smoking marijuana and driving are overrated, says University of Toronto researcher Alison Smiley.
