臺灣籍旅美老師今天交給我們的句子是：

Due to its safer nature, marijuana is often suggested as an alternative to alcohol. However, heavy use can be harmful. Since pot smoke is chemically very similar to tobacco smoke, heavy pot smokers are at risk for some of the same health effects as cigarette smokers, like bronchitis and other respiratory illnesses.
由于大麻本質上比酒精飲料安全，因此通常會建議拿它來取代酒，但吸食過多可能會對身體有害。因為吸大麻與抽煙從化學效應上來說非常類似，所以重度的大麻吸食者很有可能會遭遇某些與吸煙者相同的健康問題，像支氣管炎和其他呼吸道的疾病。
