NT, I've heard/read good things about personally. I've tried it at doses (I think I should have went ^ in dosage) that made me catch somewhat of a high. I was pretty sociable around people, I did have some body tingles, and as of last night, and previously it was also relaxing/sedative)
I don't know if it was the 30mg of diazepam or the decent quality coke I sniffed that may have dampened the experience somewhat? It is light tan-goldish in color, with a somewhat crystally consistency. My buddy and I tried it was starting to feel a little something, smoked a strong high-grade strain called "Ice Cream", and then both felt extremely tired. I woke up in my clothes the next morning haha. It wasn't like a benzo blackout though.
