El cannabis no sirve para aliviar el dolor pero s\u00ed lo hace m\u00e1s tolerable para algunas personas, seg\u00fan indica un estudio de la universidad inglesa de Oxford \u00a0en el Reino Unido. Los autores del estudio, que publica en su \u00faltimo n\u00famero la revista Pain, descubrieron, mediante un experimento en el que utilizaron esc\u00e1neres cerebrales, que la sustancia psicoactiva del cannabis reduc\u00eda la actividad en partes del cerebro asociadas a la parte emocional del dolor. En cambio, esos cambios no se registraron en la parte del cerebro asociada directamente a la sensaci\u00f3n de dolor, que es la que se activa con otro tipo de f\u00e1rmacos. Los expertos se\u00f1alan que el cannabis puede hacer m\u00e1s tolerable el dolor, aunque no en todos los casos, ya que algunas personas no son sensibles a sus efectos o estos no les benefician. El equipo de investigadores del centro de resonancias magn\u00e9ticas del cerebro de la universidad de Oxford, dirigido por Michael Lee, bas\u00f3 sus conclusiones en un peque\u00f1o experimento con doce personas sanas. El experimento llevado a cabo a estas personas se les hizo un seguimiento de la actividad cerebral despu\u00e9s de administrarles una pastilla de 15 mg de THC, la sustancia psicoactiva del cannabis que causa la sensaci\u00f3n de subid\u00f3n, y de provocarles dolor unt\u00e1ndoles en la pierna una crema con el componente que da el picor a las guindillas.<\/p>\n

Tambi\u00e9n se les hizo ese seguimiento administr\u00e1ndoles un placebo en lugar de las sustancias anteriores. En general, los investigadores observaron que, con el THC, los voluntarios valoraban que el dolor \u2014con la misma intensidad\u2014 era m\u00e1s tolerable. Adem\u00e1s, notaron que se activaba la regi\u00f3n del cerebro que determina \u00abla reacci\u00f3n emocional al dolor\u00bb, y no la que codifica \u00abla sensaci\u00f3n\u00bb de dolor, se\u00f1ala el doctor Lee. Tambi\u00e9n detectaron ciertos cambios en la actividad cerebral de las personas a quienes el cannabis hizo m\u00e1s efecto, lo que indica que en el futuro se podr\u00eda llegar a predecir qu\u00e9 personas pueden beneficiarse m\u00e1s de su consumo, apunta el experto. De todas formas, Lee subraya en el art\u00edculo que, para corroborar estas conclusiones, har\u00eda falta un estudio m\u00e1s amplio con personas con dolor cr\u00f3nico y por un plazo m\u00e1s largo de tiempo. El cannabis no sirve para aliviar el dolor pero s\u00ed lo hace m\u00e1s tolerable para algunas personas, seg\u00fan indica […]<\/p>\n","protected":false},"author":1,"featured_media":1748,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_uf_show_specific_survey":0,"_uf_disable_surveys":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[14],"tags":[86,10,217,11,218,35,1206,472,886,1207,1202,549,1208,1188,1209,476,1210],"class_list":["post-1747","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cannabis-medicinal","tag-abono-cannabis","tag-abono-ecologico","tag-abono-foliar","tag-abonos-ecologicos","tag-abonos-foliares","tag-abonos-marihuana","tag-alivio-del-dolor-con-marihuana","tag-cannabis-medicinal-2","tag-cannabis-terapeutico","tag-fertilizante-eco","tag-fertilizante-organico","tag-fertilizantes-ecologicos","tag-fertilizantes-marihuana","tag-fertilizantes-organicos","tag-fetilizante-ecologico","tag-marihuana-medicinal","tag-marihuana-terapeutoca"],"_links":{"self":[{"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/posts\/1747","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/comments?post=1747"}],"version-history":[{"count":0,"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/posts\/1747\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/media\/1748"}],"wp:attachment":[{"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/media?parent=1747"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/categories?post=1747"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/agrobeta.com\/agrobetablog\/wp-json\/wp\/v2\/tags?post=1747"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
