Study: Cannabis Inhalation Not Associated With COPD, Other Tobacco-Related Harms

UNITED KINGDOM: Cannabis smoke exposure, even long-term, is not positively associated with chronic obstructive pulmonary disease (COPD), lung cancer, or irreversible airway damage, according to a literature review published in the journal Breathe.

Study: Cannabis Smoke Exposure Doesn’t Significantly Impact Lung Health

CALIFORNIA: Cannabis smoke exposure is not particularly detrimental to lung health and is not associated with the onset of lung cancer, emphysema, or COPD, according to data published in the journal Chest.

Donald Tashkin of UCLA’s David Geffen School of Medicine reviewed dozens of studies assessing cannabis smoke exposure and lung health, involving thousands of subjects.

He reports: “Although regular smoking of marijuana is associated with an increased risk of symptoms of chronic bronchitis and evidence of inflammation and injury involving the larger airways, lung function findings, although mixed, do not provide compelling evidence that habitual marijuana smoking in the manner and amount that it is generally smoked increases the risk of COPD, at least at the population level. Despite the presence of carcinogens in marijuana smoke in concentrations comparable with those that are found in tobacco smoke, the weight of evidence from well-designed epidemiologic studies does not support the concept that habitual marijuana use in the manner and quantity in which it is customarily smoked, when adjusted for tobacco, is a significant risk factor for the development of lung cancer.”

Studies also fail to show a relationship between cannabis smoking and decrements in lung function, and “argue against an association of marijuana with clinically significant emphysema.”

Tashkin’s findings are similar to those of past reviews finding that cannabis smoke exposure fails to possess the same sort of significant adverse pulmonary effects as does tobacco.

New Study: Marijuana Smoke Exposure Not Linked To Poor Lung Health

COLORADO:  Long-term exposure to cannabis smoke is not associated with significant adverse effects on pulmonary function, according to clinical data published in the journal Chronic Obstructive Pulmonary Diseases.

A team of investigators led by researchers at the Colorado School of Public Health assessed the relationship between marijuana use and respiratory function in a cohort of 2,300 subjects ages 40 to 80, many of whom also smoked tobacco.

Authors reported, “Neither current nor former marijuana use was associated with increased risk of cough, wheeze, or chronic bronchitis when compared to never marijuana users. … Current and former marijuana smokers had significantly higher FEV1 (forced expiratory volume) … when compared to never users. … Both current and former marijuana use was associated with significantly less quantitative emphysema … when compared to never users, even after adjusting for age, … current tobacco smoking pack years, and BMI. … In agreement with other published studies, we also did not find that marijuana use was associated with more obstructive lung disease.”

Researchers also reported that the long-term combined use of tobacco and cannabis was not associated with any additive adverse effects on the lungs. They concluded, “Among older adults with a history of tobacco use, marijuana use does not appear to increase risk for adverse lung function. … There may be no to little increased risk of marijuana use for a further increase in respiratory symptoms or adverse effects … among those with a history of concomitant tobacco use.”

Prior longitudinal studies assessing the effects of long-term cannabis smoke exposure on lung function have similarly reported that subjects’ marijuana use history is not positively associated with increased incidences of chronic obstructive pulmonary disease (COPD), lung cancer, or with other significant detrimental effects on pulmonary function.

Tilray Receives License to Produce Medical Cannabis In The European Union

Company Announces €20 Million Investment to Build EU Campus and Begin Operations this Year

PORTUGAL: Tilray has announced plans today to invest up to €20 million in a European Union Campus after receiving licenses from the Government of Portugal to import cannabis genetics and to cultivate cannabis for medical purposes.

“Tilray’s EU Campus is another strategic milestone as we aim to build the world’s most trusted and admired medical cannabis brand,” said Brendan Kennedy, Chief Executive Officer of Tilray. “For the past two years we’ve been working hard to find the right location for cultivation, processing, and research facilities to serve rapidly growing demand for high-quality medical cannabis products in Europe. Portugal has the ideal climate to cultivate cannabis, a highly-skilled health care workforce, and a vibrant research community. It’s more environmentally-friendly and cost-effective to supply European patients from Portugal than from northern climates.”

State-of-the-Art EU Campus Will Begin Operations This Year

To establish the EU Campus, Tilray will invest up to €20 million through its affiliate, Tilray Portugal Unipessoal Lda., in multiple facilities located in and around the BIOCANT Research Park in Cantanhede, Portugal. The EU Campus will include indoor, outdoor, and greenhouse cultivation sites, as well as facilities to process, package, and distribute medical cannabis and cannabinoid-derived medical products. As a part of the BIOCANT biotechnology and life sciences research park, the EU Campus will serve as a hub supporting Tilray’s clinical research and product development efforts across Europe.

Tilray is currently leasing laboratory and indoor cultivation space within BIOCANT. This month, Tilray will begin construction on a greenhouse and a processing facility on property purchased by the company. Phase one of the project, which is expected to be complete by spring of 2018, includes an indoor laboratory and genetics bank, outdoor cultivation sites, a 10,000 m2 greenhouse, and a 1,500 m2 processing facility. Subsequent phases, which are expected to be completed by 2020, will add 15,000 m2 of greenhouse cultivation space and another 1,500 m2 for processing. Over the next three years, the project is expected to create 100 direct jobs, including highly-skilled positions.

EU Campus Accelerates Tilray’s Global Expansion Strategy

In response to considerable unmet need for high-quality medical cannabis, Tilray is investing aggressively to expand its operations around the world. In addition to Tilray Portugal Unipessoal Lda., Tilray has wholly-owned subsidiaries in Germany (Tilray Deutschland GmbH), Canada (Tilray Canada Ltd.), and Australia and New Zealand (Tilray Australia and New Zealand Pty. Ltd.).

Tilray has a proven track record as a global pioneer in the medical cannabis industry:

  • In 2014, Tilray was one of the first companies to be federally-licensed to cultivate, process and distribute medical cannabis in Canada.
  • In December 2016, Tilray became the first medical cannabis licensed producer in North America to be GMP-certified in accordance with the European Medicines Agency’s (EMA) Good Manufacturing Practice (GMP) standards. GMP certification is the most rigorous standard that manufacturers of medical products must meet in their production processes. In countries new to medical cannabis, GMP certification provides regulators and health care providers with certainty that Tilray products are a safe and smart choice.
  • In 2016 and 2017, Tilray launched clinical research partnerships with world-leading hospitals and universities to study the safety and efficacy of medical cannabis for a diverse range of conditions, including post-traumatic stress disorder (PTSD), chronic obstructive pulmonary disorder (COPD), pediatric epilepsy, and chemotherapy-induced nausea and vomiting (CINV).
  • Throughout the last year, Tilray became the first company to legally export medical cannabis products from North America to the European Union, Australia, New Zealand, and South America. Tilray products are currently available in six countries spanning four continents.

By the end of 2017, Tilray expects to export medical cannabis products to five more countries. The company also anticipates announcing federal licenses from additional countries, as well as research partnerships in Portugal, Germany, and other countries around the world.

Tilray Announces Support For Clinical Trial Examining Cannabis And Chronic Lung Disease

CANADA: Tilray, a global leader in medical cannabis research and production, today announced a partnership with the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal, one of the world’s premier public academic and research institutions, to study the effects of vaporized cannabis on symptoms associated with chronic obstructive pulmonary disease (COPD).

The Phase II trial will study the efficacy of medical cannabis on breathlessness, and exercise tolerance in symptomatic patients with advanced COPD. Patients with COPD suffer from chronic, progressive lung diseases that obstruct airflow and can cause irreversible lung damage without intervention. The pathophysiological hallmarks of COPD include expiratory flow limitation; pulmonary gas trapping and lung hyperinflation; gas exchange abnormalities; and mucus hypersecretion. These pathophysiological hallmarks are linked to breathlessness, loss of autonomy, and a diminished quality of life. Patients with COPD also often avoid exercise, leading to psychological co-morbidities, such as anxiety and depression, and a decrease in overall health.

COPD is a leading cause of morbidity, mortality, and socioeconomic burden in Canada and around the world. Estimates suggest that approximately 17% of Canadian adults over the age of 40 suffer from COPD. Symptom management is critical for COPD patients to ensure that their condition remains stable and their quality of life is maintained. Nonetheless, an estimated 45-90% of adults with advanced COPD suffer from chronic and disabling physical activity-related breathlessness, despite optimal treatment of their underlying lung disease with existing and approved pharmacotherapies (e.g., bronchodilators, corticosteroids). There is a critical need to develop more effective therapies for COPD.

The research team led by Drs. Dennis Jensen and Jean Bourbeau will conduct the trial at the McConnell Centre for Innovative Medicine of the RI-MUHC. “Adjunct therapies targeted to relieve breathlessness and improved exercise tolerance are needed to enhance health outcomes for adults with advanced COPD, and medical cannabis is a potential therapy of interest,” said Dr. Jensen. Patient recruitment for the trial, which will involve 20 participants, is already underway, and the trial is expected to conclude later this year.

“Tilray is proud to support this important research,” said Dr. Catherine Jacobson, Director of Clinical Research at Tilray. “If we find that vaporized cannabis is safe, well-tolerated, and effective, we can conduct further research to help people with COPD and other medical conditions manage their symptoms effectively.”

Tilray is committed to advancing the science and safety of medical cannabis products by supporting clinical research. The COPD trial is one of several research efforts underway. In Canada, Tilray supports additional clinical trials focused on pediatric epilepsy at SickKids Hospital and post-traumatic stress disorder at the University of British Columbia. In Australia, Tilray has partnered with the University of Sydney and New South Wales Government to study medical cannabis as a treatment for symptoms of chemotherapy-induced nausea and vomiting.
