Salvia divinorium for the win. Try it, before legislation passes and it becomes illegal.
Salvia has a reverse tolerance. Meaning, you might take a hit and trip today. Three days later, you take a smaller hit, and you trip harder than you did initially. Furthermore, it has no possibility to retain addiction based on its' physical properties. In fact, you may have Salvia, and not WANT to do it. I've had two grams of salvia for the last year or so. While I find the trip intense, and aweing, there's no drive pushing me to do it. It's like as if there's no time, or place good enough to experience it.
The trip itself is only a few minutes long, and it's come-down effects are almost non-existant. Meaning, 10 minutes of smoking Salvia, you retain the same well being you had before smoking it. Except now, you've got something deep, and metaphysical to ponder.
I do stress, it is NOT a social experience. Salvia is something you do camping, or in some other beautiful sceneic place, where you are neither influenced by the sounds of society, or other people speaking, because these things can incorporate themselves into the short experience.
One last thing about Salvia. Everybody, including myself, that's tried it, swears that there's a seperate, invisible female presence during the short trip. You might even end up having a conversation with her. I've definetly had trips where I've interacted with a presence that wasn't there.
A very powerful psychedelic, and dissociative.
