I loved acid as a late-teen. I took a lot. I didn't take the view that it should be legalized; I was OK with it, but it wasn't hard to imagine someone getting seriously screwed-up by it. Two of my friends were hospitalized for psychiatric disorders after taking it, but I suspect they were both latent schizophrenics.
So I'd talk about it enthusistically (like any acid-head!), but I'd never recommend itto anyone.
I used to share this attitude, but seeing a close friend have a complete break and lose his life over some recreational partying changed my view.
