Background: Observational studies investigating associations between cannabis use and blood pressure (BP)/hypertension are inconsistent.
Methods: Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) were analyzed for five 2-year cycles between 2009 and 2018 representing 9,783 middle-aged adults (35-59 years). Hypertension was defined as systolic BP (SBP) ≥130, diastolic BP (DBP) ≥80, or a BP medication. Sample-weighted multivariable logistic regression models were used to assess associations between cannabis use and BP and hypertension.
Results: One quarter of respondents (n = 2,228) reported a history of monthly cannabis use for more than 1 year, which was consistent over the study period (P for trend = 0.75). Approximately 48% (n = 4,831) met the definition of hypertension. While a significant positive trend was seen over time for mean SBP and DBP (P = <0.01 for both), no significant trend was seen in prevalent hypertension (P for trend = 0.23). In adjusted models, compared with never use, a history of monthly cannabis use for more than 1 year was not associated with increased BP (mean SBP: 124.5 mm Hg (95% confidence interval [CI], 122.4-126.6) vs. 122.6 (95% CI, 120.9-124.2); DBP: 74.7 mm Hg (95% CI, 73.1-76.2) vs. 74.1 (95% CI, 72.8-75.4)), or prevalent hypertension (odds ratio = 0.88 (95% CI, 0.62-1.24)). Results from analyses of duration of monthly use, and recency and frequency of recent use were similar.
Conclusions: A history of monthly cannabis use for more than 1 year was not independently associated with either increased BP or prevalent hypertension in a nationally representative sample of middle-aged US adults.
