It doesn't matter. Look further up the discussion thread and you'll see that was my original point: Some people may mix weed with other drugs but that's irrelevant for the linked story.
Look further up. I wasn't the one who mentioned it. I was the one who replied and said it wasn't relevant.
Then someone said I was wrong because people don't actually mix drugs like that, and I contradicted them based on personal knowledge of it happening.
Then you asked me why it matters, perhaps not realizing that I had already said it does not, further up the thread. Now you're saying it's not worth mentioning. I agree, which is why I made my original comment way up the thread, so this has become a bit circular.
