I don't think so. Why that is, is because ancient-time cannabis was totally different. As I just mentioned, in the 1960s cannabis was different. The hippies who did this drug could not necessarily do the same thing here. Also, since the Chinese government took over 50 or 60 years ago, all of the substances have been strictly banned. Now, it's a very strict penalty, so that's why there's almost zero research and zero exposure to marijuana. It's very difficult to get that.
The second one is, even for Chinese traditional medicine, the standard is different from the western medicine here. I do not think they're practising advanced medicine either.
