Is the literature comparing alcohol and heroine with actual data? Along what metric(s) is alcohol worse than heroine?
If this is actually true, the real takeway is that heroine is not nearly as bad as we've been led to believe and we should all go experiment this weekend.
There are some drug harm rankings, yes, but I haven't studied it so can't say what's the actual consensus of the field experts. I think I just saw this "alcohol is more harmful from alcohol" a few times in the articles.
