Fwiw, have been messing with vaping the 'pure white' for awhile now -- maybe a little more fun than other methods, but still pretty similar effects.
Not to mention, there's a feeling of being on the borderline of "OD'ing" with it all the time.
The last time I messed with "pure white", I messed with it for like 3 days straight, never really enjoying it, and in the end found myself wandering around the house talking to the walls and asking them "are you it? Is she it? Is he it? What's it? am I it? Are they it? Explain it. Reveal it. Define it"....
Fun, fun, fun... not.
Thinking of trying the 'salts' again that I mentioned in an earlier posting -- if they're again much better, it may be time for peeps to look into that brand name, despite the stigma of media attention & cheesy selling techniques.
There was something very different about it from the 'pure white' -- in particular, the licorice-y odor. The 'pure white' is basically odorless until insufflated.
Could also be, of course, that the 'salts' contain something in addition to MDPV, but it felt very much like peevee to me.
