You can just take the DNA code from marijuana or poppies or coca leaves and cut and past that gene and put it into yeast, and you can take those yeast and make them make the cocaine for you, or the marijuana, or any other drug.
你们可以仅仅从大麻或者罂粟或者古柯叶里 提取DNA编码， 接着剪切并复制那段基因， 继而将它放入酵母中， 然后你可以取出那些酵母 并且用它们来为你们制造可卡因， 或者大麻，或者其他任何毒品。
