@Lizzie NO. Jin is a recovering junkie and had a big amount of drugs in his system a few days ago. Matthew keeps him drugged making him a junkie again. He is doing the same mistakes Brandon did except sending him to jail. He is not allowed to drug Jin no matter what. He is horrible for doing that. And Jin could easily survived taking down all those gangsters, he did while on drugs not long ago but there's no going back from being a junkie again, he cannot survived that.
