I just want to say that i have seen only a few reports of vaporizing 2c-p, and wanted to give my opinion.
Vaporizing 2c-p is my absolute favorite route of ingestion. it has a really fast 2 minute come up, and levels off into a nice 6-8 hour trip. The 3 hour come up time is just a real turn-off for me, and snorting it just burns so fucking bad. when i smoke it, i usually smoke 2 milligrams at a time, and repeat until i'm at my desired level of psychedelia. 2c-p is the first 2c-x that I've tried, and i do have to say that while i love it, it has yet to blow my mind anymore than high doses of LSD or any of the stronger tryptamines(IMO strong ones like 4-AcO-DMT are far more mind bending than 2c-p). My highest doses were 13 milligrams orally and about 10 milligrams smoked over the course of two hours(that was a pretty intense time). all in all, i really do love this compound and plan to keep it in my collection for a long time. it really does become almost like the perfect psychedelic for me, especially when smoked; its not to ego shattering to me, and it has spectacular open and closed eye visuals.
