Er was eens een plant… een papaverplant om precies te zijn. Uit die papaver kon opium worden gewonnen en dat spul bleek wel een hele bijzondere werking te hebben: het nam je pijn weg. De opium werd gebruikt om allerlei pijnstillers te maken: die pijnstillers noemen we opioïden en die zijn niet meer weg te denken binnen de geneeskunde. Helaas zijn ze niet zonder gevaar, want opioïden kunnen enorm verslavend zijn en dat hebben we geweten. In Amerika is er een opioïden epidemie los gebarsten met meer dan een half miljoen doden. Daar zijn de afgelopen jaren talloze boeken en documentaires ...

Il premio Nobel è uno dei più prestigiosi riconoscimenti culturali che possa essere tributato a una persona. Ma è ben lungi dall’essere un vaccino contro le cantonate... fisici, chimici, medici e letterati, tutti premi Nobel, ne sono stati vittime. Il libro racconta in modo brillante e divertente le bizzarre teorie e i clamorosi errori di alcuni premi Nobel. Questo significa che il prestigioso premio svedese è una cosa poco seria? No! Dimostra soltanto che il principio di autorità nella scienza non ha alcun valore: più che l’ipse dixit, contano i fatti!
