This does not require rationality at all, not in the sense you mean. If a few tweakers and crackheads accidentally fall into this pattern of behavior then they will get more drugs. Other tweakers and crackheads (and junkies too!) will notice, and wonder how this other jackass gets to get high more than them. They will start to imitate them cargo cult style... but, cargo-culting actually works when you accidentally imitate the mechanisms that cause you to get the result that you want. And more will imitate still.

And not a single crackhead, junkie, or tweaker will have rationally worked through the process to getting high more often. That part was unnecessary all along. Smart people often misunderstand the raw power of stupidity... if it worked so poorly, then why are there billions of idiots?
