This is a good example of how the past doesn’t go anywhere. Those drugs are still around as much as they ever were, or in even greater numbers. But we all know what they are now and what they do. There’s nothing to talk about so their names drop off the cultural airwaves. They’ve settled into the culture. You don’t hear about them, but that doesn’t mean they’re not around. The past doesn’t go anywhere. The future is just laid on top of it.
