Associations Between Cannabis, Psychosis, and Schizophrenia in Adolescents

The effects of cannabis use on the brain, mind, and body have been studied for decades. The developing brain, particularly the adolescent and young adult brain, undergoes critical development that makes it especially susceptible to the effects of cannabis use. Among the adverse effects of cannabis use in adolescence and young adulthood, psychosis and psychotic disorders (e.g., schizophrenia) have been examined. The association of cannabis use with schizophrenia was first elucidated in a Swedish study of army conscripts. Specifically, conscripts reported their cannabis use exposure and were followed longitudinally to assess the emergence of schizophrenia. The authors found that those who reported persistent cannabis use during adolescence had higher rates of schizophrenia diagnoses. Notwithstanding this correlation, a causal relationship has not yet been established between adolescent cannabis use and schizophrenia. Some believe that in the premorbid phase of schizophrenia, one may self-medicate with cannabis, accounting for the correlational relationship. However, this evidence is not supported by the literature. Prolonged, frequent use of exogenous cannabinoids such as phytocannabinoids and synthetic cannabinoids perturb the endocannabinoid system, particularly during the critical period of adolescence. Many researchers believe this perturbation contributes to psychosis and the pathogenesis of schizophrenia. In this review, I demonstrate how cannabis may contribute to symptoms of psychosis and associated with diagnoses of schizophrenia. PubMed and Google Scholar were used with the following search terms cannabis-induced psychosis AND schizophrenia. These search terms were narrowed by clicking on adolescent. Also, based on the diathesis-stress model, I explored how cannabis may be one of many neurological insults leading to the onset of schizophrenia. In the future, research should be conducted focusing on other drugs as a trigger for schizophrenia

Distributions on unbounded moment spaces and random moment sequences

In this paper we define distributions on moment spaces corresponding to measures on the real line with an unbounded support. We identify these distributions as limiting distributions of random moment vectors defined on compact moment spaces and as distributions corresponding to random spectral measures associated with the Jacobi, Laguerre and Hermite ensemble from random matrix theory. For random vectors on the unbounded moment spaces we prove a central limit theorem where the centering vectors correspond to the moments of the Marchenko-Pastur distribution and Wigner's semi-circle law.Comment: Published in at http://dx.doi.org/10.1214/11-AOP693 the Annals of Probability (http://www.imstat.org/aop/) by the Institute of Mathematical Statistics (http://www.imstat.org

The atomic electric dipole moment induced by the nuclear electric dipole moment; the magnetic moment effect

We have considered a mechanism for inducing a time-reversal violating electric dipole moment (EDM) in atoms through the interaction of a nuclear EDM (d_N) with the hyperfine interaction, the "magnetic moment effect". We have derived the operator for this interaction and presented analytical formulas for the matrix elements between atomic states. Induced EDMs in the diamagnetic atoms 129Xe, 171Yb, 199Hg, 211Rn, and 225Ra have been calculated numerically. From the experimental limits on the atomic EDMs of 129Xe and 199Hg, we have placed the following constraints on the nuclear EDMs, |d_N(129Xe)|< 1.1 * 10^{-21} |e|cm and |d_N(199Hg)|< 2.8 * 10^{-24} |e|cm.Comment: 8 pages 1) Some typos are corrected. 2) A comparison of contributions to the atomic EDM due to the nuclear EDM and the nuclear Schiff moment is adde
