Two explanations have been proposed for this paradoxical finding. One posits that \u03949-tetrahydrocannabinol (THC) in cannabis desensitizes adipose CB1 cannabinoid receptors, stopping their stimulating effects on lipogenesis and adipogenesis. Another explanation is that THC exposure in adolescence, when habitual cannabis use typically starts, produces lasting changes in the developing adipose organ, which impacts adult systemic energy use. Here, we consider these possibilities in the light of a study which showed that daily THC administration in adolescent mice produces an adult metabolic phenotype characterized by reduced fat mass, partial resistance to obesity and dyslipidemia, and impaired thermogenesis and lipolysis. The phenotype, whose development requires activation of CB1 receptors in differentiated adipocytes, is associated with overexpression of myocyte proteins in the adipose organ with unchanged CB1 expression. We propose that adolescent exposure to THC causes lasting adipocyte dysfunction and the consequent emergence of a metabolic state that only superficially resembles healthy leanness. A corollary of this hypothesis, which should be addressed in future studies, is that CB1 receptors and their endocannabinoid ligands may contribute to the maintenance of adipocyte differentiation during adolescence.<\/jats:p>","DOI":"10.3390\/cells13050461","type":"journal-article","created":{"date-parts":[[2024,3,6]],"date-time":"2024-03-06T04:03:50Z","timestamp":1709697830000},"page":"461","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Overactivation of the Endocannabinoid System in Adolescence Disrupts Adult Adipose Organ Function in Mice"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4096-6953","authenticated-orcid":false,"given":"Kwang-Mook","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Anatomy and Neurobiology, University of California, Irvine, CA 92697, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Neurobiology, University of California, Irvine, CA 92697, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniele","family":"Piomelli","sequence":"additional","affiliation":[{"name":"Department of Anatomy and Neurobiology, University of California, Irvine, CA 92697, USA"},{"name":"Department of Biological Chemistry, University of California, Irvine, CA 92697, USA"},{"name":"Department of Pharmaceutical Sciences, University of California, Irvine, CA 92697, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1002\/osp4.161","article-title":"A narrative review of the construct of hedonic hunger and its measurement by the Power of Food Scale","volume":"4","author":"Muratore","year":"2018","journal-title":"Obes Sci Pract."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1080\/09540260902782810","article-title":"Cannabinoids and appetite: Food craving and food pleasure","volume":"21","author":"Kirkham","year":"2009","journal-title":"Int.
