Just tell people in such a way that only the kind of people you'd want to have higher status will pay attention.

For example, by posting it on lesswrong!

Well, the more people who know about it, the greater the chance that one of them will tell someone about it who I'd prefer not to have high status. I guess there are decently big taboos against taking drugs in our culture, so it probably wouldn't spread like wildfire. Actually, right now I have the opposite problem: I have friends who I'd like to be higher status and I'm trying to persuade them to try it but they won't.
