Marijuana legalization will eradicate the illegal markets which distribute marijuana that has been cut or weighted with far more harmful compounds than the weed itself. Here is a case of lung damage from marijuana contaminated with silicon dioxide particles which add weight and make low grade cannabis sparkle like high grade product. Talc and ground glass have also been used in this manner. Once again we see how prohibition is far more harmful on all levels than is legalization, unless one is a drug war/treatment industry misery profiteer. Also notice the first line in the abstract report and how it promotes disinformation as accepted fact: "the respiratory toxicity of cannabis is well known today" is a falsehood, in fact the bulk of research on marijuana-only smokers finds that they have superior lung function compared to nonsmokers and a reduction in the likelihood of developing lung cancer, again, compared to nonsmokers! How is this possible? Because the cell-nurturing and protective effects of cannabinoids in marijuana are vastly more beneficial than the by products of combustion are harmful. Cannabinoids reduce inflammation, oxidation and attack and kill cancer cells thereby improving lung health. It is quite amazing.

Electronic address: email@example.com. Abstract: The respiratory toxicity of cannabis is well known today. (Editor note: This assertion is not supported by evidence, it is an unscientific statement of bias not fact) Along with the classic cannabis 'joint', there are other ways of consuming it, which should be known. Smoking cannabis that has been cut with micro-particles of silicon dioxide may cause hemoptysis. We will describe here the case of a young 16-year-old man who was in the hospital because of hemoptic expectoration. The etiologic investigation was negative, in particular a thoracic scan and a bronchial fiberscope. Questioning the patient afterwards allowed us to discover the inhalation of cannabis 2 h before the hemoptysis, cannabis mixed with micro-particles of silicon dioxide. Stopping inhalation stopped the symptoms. Pediatricians should be familiarized with such practices. Silicon dioxide particles cause ENT problems or bronchial ones coughing, spitting, hemoptysis, wheezing. Over the long term, the risk of silicosis cannot be excluded, although a longer and more complete exposure is necessary.Copyright © 2013 Elsevier Masson SAS. All rights reserved.
