Reddit mentions of Utopiates: The Ultimate Bet with the Mind

I haven't read it yet, but I've been meaning to try out Utopiates written by Josh Finney, which sounds like a BTL focused Shadowrun setting.

In the future, science has formulated a way to distill human personalities into a drug-form. On the street, they are called Utopiates and allow the user to swap personalities with the mental imprints of other people... for a short while. Within these pages you will follow the interconnected lives of individuals who inject the souls of others. Each is a user for their own reasons, but all learn the cost of soul swapping is extremely high.

Sounds like a good time to me, I hope to get to it sometime later this year. Click the Amazon image and it gives you the first few pages of preview, and some of it almost feels like a 2e sourcebook.
