The increase in prescribed dosages is noted in a recent report on the views of physicians regarding the use of marijuana, adding that this information "surprised" most doctors when they were told during interviews. It said the doctors identified seven "logical" explanations for the trend, including the perception that Health Canada marijuana is "not as potent" as that produced and grown by patients or their suppliers. "Higher doses of Health Canada marijuana for medical purposes may be warranted to achieve the same result obtainable through more potent strains," added the report. Completed by Les Etudes de Marche Createc, the study found physicians were unclear about Health Canada's maximum dosage recommendation, stating that "not one participant was able to guess the maximum level." For most doctors, the report said, overdose or dosage beyond an "optimal" limit was not a concern or even a consideration. The study found unanimous agreement and even "enthusiastic support" among doctors for Health Canada to begin supplying dried marijuana to pharmacists trained to dispense it to patients, although they suggested that the quality be improved and the price be reduced while insuring that medical insurance programs cover the cost. The reporting of the trend follows Health Canada's campaign last summer to keep doses below five grams, which included postings on its website referring to studies that indicated that most medical users need only one to three grams daily. Other explanations for rising dosages offered by the doctors included observations that no guidelines on a common measurement standard -- "puff, joint versus gram" -- forcing them to rely on their patients. - --- MAP posted-by: Derek
