People who smoke pot and drink are twice as likely to do both at the same time than to do just one, with the combo associated with bad decision-making; and chronic(慢性) pot smokers who had not indulged in(沉湎于) a month were still more likely to have faulty(错误的记忆) memories than were nonsmokers(不抽烟的人).
Marijuana is the drug of choice for people who drink alcohol. And people who use both are twice as likely to do so at the same time than to indulge in(沉湎于) just one or the other.The data came from self-reported answers that more than 8,600 people provided to what’s called the National Alcohol Surveys, done by phone in 2005 and 2010.
People who used pot and alcohol were about twice as likely to drive drunk than those who just drank. And they doubled(两倍) their chances of what are referred to as negative social consequences, such as arrests, fights and job problems.
Meanwhile, another new study finds that if you’re chronically(长期地) stoned(醉酒的), you’re more likely to remember things differently from how they happened, or not at all.
Researchers showed a series of words to people who do not use marijuana(大麻) and to regular pot users who had not partaken in(分享) a month. A few minutes later, all participants were shown the same list of words along with other words. The volunteers were then asked to identify only the original words. The pot smokers thought more of the new words were in the original list than did the nonusers(弃权的人). And brain scans revealed that the regular pot users showed less activity in brain regions associated with memory and cognitive resources than did the nonusers.
Marijuana use is much more acceptable than it used to be, both socially and legally(合法的). But these two studies show that pot, especially when mixed with alcohol, can affect the brain in negative ways, both immediately and in the long run.
