题目：Snorted substances reach the brain faster than injected substances.
原文：Scientists have found that a smoked substance reaches the brain more quickly than one swallowed, snorted (such as cocaine powder) or even injected.
题目和原文都有比较，比较的关键词是reach the brain faster than，原文中有一个同义词转换结构reaches the brain more quickly than。其中faster和more quickly构成了同义词转换的用法。题目中比较的两方面是snorted substances和injected substances。而原文的比较内容是a smoked substance和swallowed、snorted (such as cocaine powder) or even injected。题目中的比较对象在原文中是并列关系，因此无法进行比较，所以答案判断为Not Given。
