Marrs et al. show that the serine hydrolase α/β-hydrolase domain 6 (ABHD6) controls the accumulation and efficacy of the endocannabinoid 2-arachidonoylglycerol at cannabinoid receptors. ABHD6 is located post-synaptically and its selective inhibition permits the induction of cannabinoid receptor–dependent long-term depression by otherwise subthreshold stimulations.
