Fördelar vs nackdelar med snus?

Even people without any diagnosed disorder might benefit from nicotine. Psychologist Jennifer Rusted of the University of Sussex in Britain calls the drug “the most reliable cognitive enhancer that we currently have.” In addition to improving visual attention and working memory, nicotine has been shown by Rusted to increase prospective memory: the ability to remember and implement a prior intention. (When your mother asks you to pick up a jar of pickles at the grocery store on the way home, she’s saddling you with a prospective memory challenge.)

“It’s a small effect, maybe a 15 percent improvement,” Rusted says. “It’s not something that’s going to have a massive impact in a healthy young individual. But we think it’s doing it by allowing you to redeploy your attention more rapidly.” In short, the drug seems to work by helping users shut out irrelevant stimuli so that important information can come to the fore.
