Conclusion: Unintentional cannabis ingestion by children is a serious public health concern and is well-documented in numerous studies and case reports. Clinicians should consider cannabis toxicity in any child with sudden onset of lethargy or ataxia.
PubMed 28888560 ↗Conclusion: Positivity mainly arises from the product content (e.g., undeclared or excessive THC, mislabeling, and contamination), the matrix, the administration route, and the sensitivity and specificity of the analytical methods.

PubMed 41942676 ↗Conclusion: Overall, CBD-containing hemp extracts show biologically plausible and clinically promising adjunctive potential for mild-to-moderate inflammatory acne, but current evidence remains preliminary. This review highlights the need for methodologically rigorous and transparent clinical studies, standardised formulations, validated outcome measures and the integration of sustainability metrics to strengthen evidence synthesis, clarify clinical relevance and guide responsible cosmeceutical development.
