ABSTRACT

BACKGROUND: The prevalence and burden of substance and opium use have increased worldwide over the past decades. In light of rapid population changes in Tehran, we aimed to evaluate the prevalence of opium and other substance use among adult residents in Tehran, Iran. METHOD: From March 2016 to March 2019, we utilized data from 8 296 participants in the Tehran Cohort Study recruitment phase (TeCS). We calculated the age-sex-weighted prevalence of substance use and the geographic distribution of substance use in Tehran. We also used logistic regression analysis to determine possible determinants of opium use. RESULT: We analyzed data from 8 259 eligible participants with complete substance use data and the average age of participants was 53.7 ± 12.75 years. The prevalence of substance use was 5.6% (95% confidence interval [CI]: 4.6- 7.1%). Substance use was more common in males than females (Prevalence: 10.5% [95% CI: 8.6- 12.6%] vs. 0.5% [95% CI: 0.2- 1.2%], respectively). The age-sex weighted prevalence of substance use was 5.4% (95% CI: 4.6-7.1%). Moreover, opium was the most frequently used substance by 95.8% of substance users. Additionally, we found that male gender (Odds ratio [OR]: 12.1, P < 0.001), alcohol intake (OR: 1.3, P = 0.016), and smoking (OR: 8.5, P < 0.001) were independently associated with opium use. CONCLUSIONS: We found that the prevalence of substance use in Tehran was 5.6%, and opium was the most frequently used substance. In addition, male gender, lower levels of education, alcohol, and tobacco consumption are the main risk factors for substance use in Tehran. Healthcare providers and policymakers can utilize our results to implement preventive strategies to minimize substance use in Tehran.

ABSTRACT

INTRODUCTION: Tobacco use is a major health concern worldwide, especially in low/middle-income countries. We aimed to assess the prevalence of cigarette smoking, waterpipe, and pipe use in Tehran, Iran. METHODS: We used data from 8272 participants of the Tehran Cohort Study recruitment phase. Tobacco use was defined as a positive answer to using cigarettes, waterpipes, or pipes. Participants who did not report tobacco use during the interview but had a previous smoking history were categorized as former users. Age- and sex-weighted prevalence rates were calculated based on the national census data, and characteristics of current and former tobacco users were analyzed. RESULTS: Age- and sex-weighted prevalence of current tobacco users, cigarette smokers, waterpipe, and pipe users in Tehran was 19.8%, 14.9%, 6.1%, and 0.5%, respectively. Current tobacco use was higher in younger individuals (35-45 years: 23.4% vs. ≥ 75 years: 10.4%, P < 0.001) and men compared to women (32.9% vs. 7.7% P < 0.001). The prevalence of tobacco use increased with more years of education (> 12 years: 19.3% vs. illiterate: 9.7%, P < 0.001), lower body mass index (< 20 kg/m2: 31.3% vs. ≥ 35 kg/m2: 13.8%, P < 0.001), higher physical activity (high: 23.0% vs. low: 16.4%, P < 0.001), opium (user: 66.6% vs. non-user: 16.5%, P < 0.001), and alcohol use (drinker: 57.5% vs. non-drinker: 15.4%, P < 0.001). Waterpipe users were younger (46.1 vs. 53.2 years) and had a narrower gender gap in prevalence than cigarette smokers (male/female ratio in waterpipe users: 2.39 vs. cigarette smokers: 5.47). Opium (OR = 5.557, P < 0.001) and alcohol consumption (OR = 4.737, P < 0.001) were strongly associated with tobacco use. Hypertension was negatively associated with tobacco use (OR = 0.774, P = 0.005). CONCLUSION: The concerning prevalence of tobacco use in Tehran and its large gender gap for cigarette and waterpipe use warrant tailored preventive policies.

ABSTRACT

Although atherosclerotic cardiovascular disease (ASCVD) and cancer are seemingly different types of disease, they have multiple shared underlying mechanisms and lifestyle-related risk factors like smoking, unhealthy diet, excessive alcohol consumption, and inadequate physical activity. Opium abuse is prevalent in developing countries, especially the Middle East region and many Asian countries. Besides recreational purposes, many people use opium based on a traditional belief that opium consumption may confer protection against heart attack and improve the control of the risk factors of ASCVD such as diabetes mellitus, hypertension, and dyslipidemia. However, scientific reports indicate an increased risk of ASCVD and poor control of ASCVD risk factors among opium abusers compared with nonusers. Moreover, there is accumulating evidence that opium consumption exerts potential carcinogenic effects and increases the risk of developing various types of cancer. We conducted a review of the literature to review the current evidence on the relationship between opium consumption and ASCVD as well as various kinds of cancer. In addition, we will discuss the potential shared pathophysiologic mechanisms underlying the association between opium abuse and both ASCVD and cancer.

ABSTRACT

There is a traditional belief among Eastern people that opium may have ameliorating effects on cardiovascular risk factors, especially diabetes; thus, it is widely used among diabetic patients. We attempted to investigate the association of opium consumption with coronary artery disease (CAD) in diabetic patients. A cross-sectional study was conducted on diabetic patients undergoing coronary angiography in our center. Out of 1925 diabetic patients included in the study, 228 were opium users, and the remaining 1697 non-opium users were used as a pool of potential comparators. Propensity scores were used to match the 228 opium consumers with 228 matched comparators for age, sex, and smoking status. The Gensini score and extent score were respectively used to assess the angiographic severity and extent of CAD. The mean Gensini score (86.9 ± 62.7 vs. 59.6 ± 43.4, p < 0.0001) and extent score (7.1 ± 2.9 vs. 5.9 ± 2.9, p < 0.0001) were significantly higher in opium user diabetic patients than in non-opium users. After adjustment for potential confounders, a dose-response relationship was observed between dose of opium and the Gensini score ( ß = 0.27, p = 0.04). There were no significant differences between the routes of opium administration (inhalation vs. oral) regarding the severity and extent of CAD. In conclusion, exposure to opium in diabetic patients may be positively associated with the risk of CAD, and with the angiographically determined severity and extent of the disease. Furthermore, dosage of opium consumption may correlate with severity of CAD.

ABSTRACT

Opioids have the highest rate of illicit drug consumption after cannabis worldwide. Opium, after tobacco, is still the most commonly abused substance in the Middle East. In addition to the ease of availability, one reason for the high consumption of opium in Asian countries might be a traditional belief among Eastern people and even medical staff that opium may have ameliorating effects on cardiovascular diseases (CVDs) as well as diabetes mellitus, hypertension, and dyslipidemia. Over the last decade, many studies have been performed on humans and animals to evaluate the interplay between opium consumption and stable coronary artery disease, acute coronary syndromes, and atherosclerosis. In this review, we conclude that opium consumption should be considered a risk factor for CVDs. Healthy individuals, as well as cardiac and diabetic patients, should be informed and educated about the hazardous effects of opium consumption on cardiovascular and other chronic diseases.

ABSTRACT

BACKGROUND: A wrong traditional belief persists among people that opium consumption beneficially affects cardiovascular disease and its risk factors. However, no evidence exists regarding the effect of opium consumption or cessation on the long-term risk of major adverse cardio-cerebrovascular events after coronary artery bypass grafting. We therefore aimed to evaluate the effect of persistent opium consumption after surgery on the long-term outcomes of coronary artery bypass grafting. METHODS: The study population consisted of 28,691 patients (20,924 men, mean age 60.9 years), who underwent coronary artery bypass grafting between 2007 and 2016 at our centre. The patients were stratified into three groups according to the status of opium consumption: never opium consumers (n = 23,619), persistent postoperative opium consumers (n = 3636) and enduring postoperative opium withdrawal (n = 1436). Study endpoints were 5-year mortality and 5-year major adverse cardio-cerebrovascular events, comprising all-cause mortality, acute coronary syndrome, cerebrovascular accident and revascularisation. RESULTS: After surgery, 3636 patients continued opium consumption, while 1436 patients persistently avoided opium use. The multivariable survival analysis demonstrated that persistent post-coronary artery bypass grafting opium consumption increased 5-year mortality and 5-year major adverse cardio-cerebrovascular events by 28% (hazard ratio (HR) 1.28, 95% confidence interval (CI) 1.06-1.54; P = 0.009) and 25% (HR 1.25, 95% CI 1.13-1.40; P < 0.0001), respectively. It also increased the 5-year risk of acute coronary syndrome by 34% (sub-distribution HR 1.34, 95% CI 1.16-1.55; P < 0.0001). CONCLUSIONS: The present data suggest that persistent post-coronary artery bypass grafting opium consumption may significantly increase mortality, major adverse cardio-cerebrovascular events and acute coronary syndrome in the long term. Future studies are needed to confirm our findings.

ABSTRACT

Opium is the second-most-commonly abused substance (after tobacco) in developing countries of the Middle East region, and in many Asian nations. One of the reasons for the high prevalence of opium abuse in these countries is a traditional belief among Eastern people, even including some medical staff, that opium might have beneficial effects on cardiovascular health and in the control of diabetes mellitus, hypertension, and dyslipidaemia. In this Perspectives article, we summarize the current understanding of the pharmacotoxicology of opium and its specific effects on glycaemic control, blood pressure, lipid profile, and atherosclerosis. On the basis of the available evidence, we believe not only that opium has no ameliorating effect on cardiovascular diseases, but also that the use of this drug might have adverse effects on these conditions. Therefore, people should be educated about the hazardous effects of opium consumption on cardiometabolic diseases.
