(WASHINGTON, Reuters)The risk of a heart attack jumps nearly fivefold during the first hour after smoking marijuana.

(路透社華盛頓電)開始抽大麻的一個小時之內(nèi)，心臟病發(fā)作的危險性幾乎會激增五倍。

this poses a particular threat to middle-aged users of the drug, especially those over age 45.

這種危險性對于中年的大麻吸食者特別嚴重，尤其是超過四十五歲的人。

The increased risk from marijuana was more dangerous than sexual intercourse for a sedentary person.

對于久坐的人而言，抽大麻所增加的危險性比性行為還高。
