BBC紀錄片《大麻 罪惡之種》 第05期：大麻與人類相遇
Because of this similarity, these new signals came to be known as cannabinoids.
由于這種相似性，這些化學物質后來被稱作大麻素。
On this buoy here, you can see quite a lot of them.
在這個浮標上，你能看到很多的海鞘。
Oh, yes.
是啊。
And, what's been found is that these compounds, the cannabinoid type compounds, they affect the time it takes for the siphon to close in response to touch.
我們發(fā)現這種化合物，也就是大麻素，影響了虹吸管被觸碰時關閉所用的時間。
And, it in fact takes longer for the siphon to close when they've been exposed to these cannabinoid compounds.
事實上，由于大麻素的影響虹，管要花更多的時間才能關閉。
Once the cannabinoid receptor evolved in the sea-squirt,
在大麻素受體從海鞘身上進化出來后，
then it was inherited by every other vertebrate animal, which followed including us humans.
它就被所有的脊椎動物所繼承，包括我們人類。
It was only a matter of time before one of these creatures would encounter the cannabis plant,
而這些動物遲早都會遇上大麻，
so that THC and the cannabinoid receptor would meet.
然后四氫大麻酚就會和大麻素受體接觸。
Since it was here in Central Asia that cannabis first proliferated, it was probably here that that first meeting took place.
由于大麻是由中亞開始繁衍的，那么初次接觸應當也是在這里。
It's not really difficult to imagine how it happened.
并不難想象他們是怎么相遇的。
I mean, no-one knows for sure when THC and the cannabinoid receptor first came together, but it has to have been here inthese mountains.
盡管沒人確切知道四氫大麻酚和大麻素受體第一次碰撞的時間，但一定發(fā)生在這些山間。
And whether it was an animal who, hungry, overcame the unpleasant taste and had a good munch on a cannabis bush.
可能是一只饑腸轆轆的動物，克服了它討厭的味道然后大快朵頤。
Or it was a bird flying around, or a rodent.
或是一只飛過的鳥兒，甚至是老鼠。
The first stoned animal is lost to history.
總之，第一個被麻醉的動物已經在歷史長河里消失無蹤。
In that very first stoned animal, THC from the cannabis plant flowed from its gut into its bloodstream and was carried to its brain.
在那第一個被麻醉的動物體內，大麻中的四氫大麻酚經其內臟進入血液，并最終到達腦部。
There, it met the cannabinoid receptor evolved so many millions of years earlier in the humble sea-squirt.
在那里，它遇到了百萬年前，由小小海鞘進化出來的大麻素受體。
And it just so happened to fit, like a key in a lock.
雙方是如此的契合，好似一把鑰匙開一把鎖。
It was inevitable that eventually cannabis would meet its perfect partner...Us.
這樣，大麻最終與它的最佳搭檔——我們人類——相遇的日子也就不久了。
It's not known exactly when humans started consuming cannabis.
人類何時開始使用大麻已無從考證。
But there's evidence that it's been used in this region for nearly three thousand years.
但有證據顯示，這個地區(qū)的人使用大麻，已經有近3000年的歷史了。
