Background: Recent studies have suggested that opium use may increase mortality from pulmonary diseases. However, there are limited comprehensive studies regarding the prevalence of Asthma and Chronic Obstructive Pulmonary Disease (COPD) among tobacco and opium users has been published. We aimed to determine the prevalence of respiratory disease among tobacco and opium users.
Methods: This cross-sectional study of tobacco and opium users and matched controls was conducted in the Kharameh Cohort, Fars, Iran. The prevalence of COPD and asthma, along with the participants demographical and spirometry data were examined.
Results: The average age of participants was 57 ± 8 years. Never smokers had a significant higher BMI (26.6 vs. 24.8), FEV1 (91% vs. 82%) and FVC (96% vs. 88%) values compared to participants with a positive smoking status. There was a statistical difference in the prevalence of COPD, asthma, and asthma COPD overlap (ACO) based on the participants smoking status, with the highest prevalence among opium and cigarette smokers, followed by opium users alone. Based on multivariate analysis, higher age, lower BMI, lower education than under diploma, cigarette smoking and opium use were significantly correlated with higher COPD prevalence; while lower age, cigarette smoking and opium use were significantly correlated with higher asthma prevalence. Illiterate participants had a significantly higher prevalence of COPD (23.6%), asthma (22%), and ACO (7.9%) among the educational groups. Regarding the prevalence of asthma, the higher socio-economic group had the lowest prevalence.
Conclusions: Opium and tobacco users had a significantly higher prevalence of respiratory diseases, along with lower lung function tests based on spirometry evaluation.

Introduction: Opium and cigarette smoking have been identified as significant cancer risk factors. Recently, the International Agency for Research on Cancer (IARC) classified opium as a Group 1 carcinogen in 2020.
Method: Using data from a multicenter case-control study in Iran called IROPICAN, involving 717 cases of bladder cancer and 3477 controls, we assessed the interactions on the causal additive scale between opium use and cigarette smoking and their attributing effects to evaluate public health relevance and test for different mechanistic interaction forms to provide new insights for developing of bladder cancer.
The association between the Glutathione S-transferase polymorphisms and addiction to opioids and methamphetamine in the Iranian population.

Introduction: Glutathione S-transferase (GST) has the ability to detoxify the cellular environment of xenobiotic compounds and by-products of oxidative stress. The expression levels of GST genes and their polymorphisms are associated with various human diseases. Methamphetamine and opiate addiction also account for a significant proportion of SUDs in Iran.

Objectives: Recent studies have suggested a potential link between opium consumption and microvascular dysfunction in coronary arteries, which may contribute to the development of coronary slow-flow syndrome. This study aims to investigate the relationship between opium use and coronary slow-flow syndrome.
Design And Setting: This retrospective study analysed medical records of patients who underwent coronary angiography at the Tehran Heart Center from 2006 to 2020.
Hypoxic brain damage in Methadone misuse: insights from MRI imaging and comparative study.

Radiology Technology Department, School of Allied Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Article Synopsis
- The study explored brain disorders, specifically hypoxia, among methadone users compared to opium users and a control group using MRI scans.
- Significant hypoxia was found in 16.7% of methadone users, while no hypoxia was detected in the other groups; MRI revealed abnormal brain imaging patterns within this subset.
- The researchers recommend routine MRI monitoring for methadone users, stricter regulations on non-prescription methadone, and better public health education to address misuse risks.
Dietary total antioxidant capacity and odds of lung cancer: a large case-control study.
BMC Cancer

Cancer Research Center, Cancer Institute, Tehran University of Medical Science, Tehran, Islamic Republic of Iran.
Article Synopsis
- The study investigates the link between dietary total antioxidant capacity (dTAC) and the risk of lung cancer (LC) in an Iranian population.
- Researchers conducted interviews and dietary assessments with over 600 lung cancer patients and 3,400 healthy controls across 10 provinces in Iran.
- Results show that higher dTAC, measured by FRAP and TRAP scores, correlates with a lower risk of lung cancer, with consistent findings across different demographic and lifestyle groups.
