Circulating Anandamide and Alcohol Craving Were Not Linked the Same Way in Both Groups
A circulating-anandamide finding in controls did not appear the same way in recently abstinent alcohol-dependent participants. A review describes this group difference without establishing an individual craving biomarker.
The comparison was population-specific
Pava and Woodward summarize a study in which recently abstinent alcohol-dependent participants did not show the increase in circulating anandamide correlated with alcohol craving in controls. Both the abstinence context and the comparison group define the observation.
Circulation is not a direct brain recording
A peripheral measurement should not be relabeled as endocannabinoid release at a particular brain synapse. Likewise, an association with reported craving does not prove that the circulating molecule caused the subjective experience.
A group difference does not create a personal cutoff
To use a measurement clinically, research would need to establish what it predicts and how reliably it does so in the intended population. The historical report does not provide that validation or a diagnostic threshold. It instead supports asking whether a proposed biomarker relationship depends on dependence status and recent exposure history. The result concerns an endogenous cannabinoid, rather than a direct measurement of THC use or impairment.
