No other drug is so infused in American culture as Marijuana, perhaps because—like alcohol—it's experienced extreme ends of social acceptance and rejection.
沒有其他毒品像大麻一樣如此深入美國文化，也許是因為－－就像酒類一樣－－它已經歷過社會認可和排擠的兩種極端。
Early on, marijuana use was portrayed with highly exaggerated effects. Propaganda films like Reefer Madness helped to spread claims that use of "demon weed" led to promiscuity, rape, and homicide.
在早期，吸食大麻是用高度誇飾的影響被描繪出來。像是《大麻瘋》的宣傳影片幫助散佈使用「惡魔毒草」會導致雜交、強暴、和殺戮的宣言。
Today with a greater understanding of the drug and its effects, public perception has completely changed to the point that 41% of Americans have tried the drug and some states have actually legalized it.
在今天，有了對此藥物和其影響更進一步的認識，大眾的認知已經完全改變，到了有41%的美國人都曾試過那藥物、且有些州確實使其合法化的程度。
So does this mean that marijuana is harmless? Not necessarily. Approximately 10% of people who use another legal substance—alcohol—would become addicted. And while, like alcohol, you might enjoy marijuana without adverse effects, your chances of becoming addicted to it are just as high as your chances of becoming addicted to alcohol.
所以這代表大麻無害嗎？不見得。大約有10%使用另一種合法物質的人－－也就是酒類－－會成癮。而儘管，像是酒類一樣，你也許可以在沒有反作用的狀況之下享受大麻，你對它上癮的機會就跟你對酒精上癮的機會一樣高。
When you smoke marijuana, THC—the active ingredient in marijuana—enters the lungs and travels through the bloodstream to the brain. Once there, THC disrupts your chemical balance, allowing dopamine—the natural chemical in your body that produces feelings of satisfaction and well-being—to flow freely.
當你吸食大麻，四氫大麻酚－－大麻裡的活性成分－－進入肺部，並穿過血流進到腦部。一旦到了那裡，四氫大麻酚擾亂你體內化學物質的平衡，讓多巴胺－－你體內產生滿足和幸福感的天然化學物質－－能夠自由流竄。
Although researchers are still exploring the long-term consequences of marijuana use, some studies show that heavy use can cause cognitive decline and addiction—especially among adolescents.
雖然研究人員仍在持續探索吸食大麻的長期後果，有些研究顯示大量吸食可以導致認知衰退和成癮－－特別是在青少年中。
At first, marijuana use may not seem to be dangerous, yet those nightly smoking sessions may overshadow school or work performance, life goals, and even family relationships. This is addiction.
首先，吸食大麻也許看似不危險，但那些夜間吸食的聚會也許會為學校或是工作上的表現、人生目標、甚至是家庭關係蒙上陰影。這是成癮。
Marijuana addiction does not disappear on its own. If you or a loved one is struggling with marijuana use, seek help today.
大麻癮並不會自己消失。如果你或是深愛的人正在與吸食大麻對抗中，今天就尋求幫助。
