**Study Design & Cohort:** This study aimed to investigate whether CBD attenuates RA progression by suppressing synovial angiogenesis and to elucidate the underlying molecular mechanisms. In vitro, cytotoxicity was determined using the CCK-8 assay, followed by evaluations of CBD’s direct effects on the proliferation, migration, invasion, and inflammatory responses of RA fibroblast-like synoviocytes (RA-FLS) were evaluated, alongside Cell Counting Kit-8 (CCK-8) for cytotoxicity screening.

**Primary Findings:** In vitro, non-cytotoxic concentrations of CBD (2.4-4.8 μM) significantly suppressed aberrant RA-FLS proliferation, migration, invasion, and pro-inflammatory cytokine secretion. Mechanistically, CBD abrogated the hypoxia-induced accumulation of hypoxia-inducible factor-1α (HIF-1α) protein in RA-FLS without significantly altering HIF1A mRNA expression. Consequently, CBD dose-dependently decreased the extracellular secretion of vascular endothelial growth factor A (VEGFA) and angiopoietin-2 (ANG-2) from RA-FLS.

**Clinical Relevance:** From a clinical practice standpoint, these findings help physicians and patients contextualize the balance between therapeutic targets and individual tolerance.

**Study Design & Cohort:** Cannabis use is increasing globally, yet the immunological effects of Δ9-tetrahydrocannabinol, the main intoxicating component of cannabis, remain incompletely understood. Given prior evidence that endocannabinoid signaling influences helminth immunity and type 2 inflammation, we investigated how sustained Δ9-tetrahydrocannabinol exposure alters immune responses to the helminth Nippostrongylus brasiliensis, which infects the lung and small intestine of mice.

**Primary Findings:** Δ9-Tetrahydrocannabinol exposure did not significantly alter infection-associated weight loss or helminth burden; however, Δ9-tetrahydrocannabinol selectively restrained infection-induced circulating eosinophils and monocytes while increasing regulatory T cells. T cell activation assays showed reduced TNFα and IFNγ secretion in splenocytes from Δ9-tetrahydrocannabinol-treated infected mice. Bulk RNA sequencing showed that Δ9-tetrahydrocannabinol shifted lung eosinophils and CD11c+ lung macrophage-enriched cells from inflammatory, fibrotic, and costimulatory pathways toward stress and metabolic-adaptive transcriptional programs.

**Clinical Relevance:** From a clinical practice standpoint, these findings help physicians and patients contextualize the balance between therapeutic targets and individual tolerance. Treatment strategies should incorporate verified product composition, precise dosage titration, and structured follow-up rather than relying on unverified claims.
