Summary: This study found that cannabis use is associated with higher lung volumes and lower midexpiratory airflow, but does not cause a decrease in the FEV1/FVC ratio, which distinguishes it from tobacco use. Furthermore, the study provides evidence that lifetime cannabis use may impair gas transfer.

Summary: Cannabis use is associated with bronchitis, increased central airway resistance, and higher vital capacity, but not with airflow obstruction or impaired gas transfer. Heavy cannabis users may experience severe lung diseases, but there is currently lacking conclusive evidence linking cannabis to chronic obstructive pulmonary disease or lung cancer.

However, the adjusted odds of symptoms did not significantly differ by device type for asthma exacerbations.

Summary: The shifting landscape in Australia's tobacco and cannabis policies and emerging new products and modes of administration may increase experimentation and the risks of addiction to these drugs. A four-class solution was identified: co-use of tobacco and cannabis, cannabis-only, tobacco-only, and non-user. Mental health issues and poly-substance use were more common among the co-users of cannabis and tobacco. Existing policies need to minimize cannabis and tobacco-related harms.

Summary: A study evaluated compliance of cannabis-licensed firms with the Cannabis Act and analyzed trends in violations regarding promotional material. Widespread violations were observed in online Canadian cannabis promotion, suggesting the need for explicit federal regulation and enforcement to protect public health and safety amid legalization. The impact of policy and enforcement of cannabis promotion in Canada would also have international implications due to the global outreach of online media.

Summary: This study describes a method of spiking nonaqueous matrices with aqueous metals standards to investigate aerosolization and recovery of the metals. It also compares various methods for nonpolar aerosol capture and subsequent analysis of 10 metals in two model cannabis matrices. Results show that not all metals that are present in the concentrate or flower can be fully recovered in the aerosol capture processes at standard voltage settings or combustion temperatures.

Summary: By examining the use of tobacco and tobacco-free blunt products among adolescents, it was found that tobacco-free blunt wraps were highly popular. This highlights the importance of assessing the specific products used to make blunts. Misclassification of blunt use as tobacco-cannabis co-use may occur if tobacco-free blunts are not taken into consideration, potentially leading to inflated estimates of tobacco use.

Summary: Many patients with cardiovascular disease also suffer from chronic obstructive pulmonary disease (COPD), but COPD is often undiagnosed and untreated. It is important for cardiologists to recognize and treat COPD in patients with cardiovascular diseases because optimal COPD treatment can have significant benefits on cardiovascular outcomes. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) publishes annual reports that serve as clinical guidelines for COPD diagnosis and management worldwide, and the recently released 2023 report provides recommendations specifically relevant to cardiologists dealing with CVD patients who may have COPD.

The results showed that both surgical and nonsurgical groups continued to use these substances up to 6 years post-surgery. The use of tobacco products/devices after surgery was associated with lower body mass index and greater weight loss.
