Extended‐release buprenorphine in adults with opioid use disorder involving poppy seed tea: An 18‐month retrospective case series

The American Journal on Addictions, Volume 35, Issue 5, Page 638-642, September 2026.
Abstract Background and Objectives Poppy seed tea (PST) contains unpredictable opioid concentrations, destabilising tolerance and increasing overdose risk. Extended‐release buprenorphine (BUP‐XR) provides sustained coverage without daily dosing. Methods Eighteen‐month follow‐up of adults (N = 3) with opioid use disorder (OUD) involving PST in Australia.

Microbiome‐Phytochemical Crosstalk Along the Gut‐Brain Axis in Alzheimer and Parkinson's Disease

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Phytochemicals remodel the gut microbiota by enriching beneficial bacteria and microbial metabolites while suppressing dysbiosis and inflammation. Through modulation of the gut–brain axis, they restore intestinal barrier integrity, regulate neuroimmune and neuroprotective signaling pathways, reduce amyloid‐β, tau, and α‐synuclein pathology, and ...

Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

The Chemical Record, Volume 26, Issue 3, March 2026.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...
