I'm new to the forums and didn't want to start a new thread on a subject that's already being discussed. I'm going to write about my experience on K2 Summit as I tried it for the first time recently due to circumstances that disallow me from smoking my 1st choice, marijuana.
It was last night, about 11:00PM, was outside with 4 friends and I was excited to try this new "weed imitator" that my friends had told me about. It was 3 grams for 32$... which I figured was not terribly expensive if it was potent.
So me and the 4 others went for a little walk into the woods and lit up bowl number 1 of the Summit. I must say I was skeptical at first, and hadn't done any research on it yet. Nothing noticeable happened for the first few minutes, and I was ready to call it weak and not worth it. But after about the 3rd bowl of it, and we were each getting about 2 good hits from each bowl, the effects were noticed. There was a strange mixture of euphoria and agitation, we would all give each other a hard time, but in a half joking way. We talked for what must have been 30 minutes, although time was definitely distorted. We were laughing and always getting louder than we should have been in the neighborhood at that time, but continuously forgetting to be quiet. It seemed to have slightly different effects on each of us though. For me and two others it was very similar to marijuana, and we still were very coherent and just vibing with it, with slight discomfort from a faster pulse, tighter chest, slight difficulty swallowing, etc., but that's happened from lot's of weed to me before also so I was not alarmed. The two others were a little less experienced with drugs in general, and were a little more far-out and almost stereotypically goofy and paranoid.
We must have smoked 5 bowls of the K2, along with some regular marijuana before we went inside to watch some TV and relax for a while. Up to this point it was hard to put my finger on how this K2 stuff was different from marijuana, I guess it seemed more intense and shorter, a little edgier, and a little harder on the body.
Much later, probably 2AM about, we were getting some food and ready to pass out upstairs when one of my friends was seeming to have a rough time, he seemed a little freaked out, which I tried to jest and put aside as paranoia and anxiety, until he actually had to sit down. Then he kind of rolled backwards onto his back and was just looking at me, but couldn't move for a second. He got up after a few seconds and said he lost control over his body for a few seconds and was having a "freak out". With my experience though, this was most likely something he talked himself into. The mind is a powerful thing, so I'm not certain that was the K2, or if he just smoked too much and it was all psychosomatic.
I didn't have any real adverse effects besides some slight motor dysfunction (didn't feel balanced correctly when walking) and pulse increase, tightness of throat, and slight paranoia, (brought on by my friend falling over, seeing things like that never helps).
Sorry this was so long, I'll try to make a short list here of the effects as experienced by me, although the marijuana in the mix will make it not a true test of the K2.
GOOD:
-Euphoria
-More social
-The "cartoon" effect as I call it, or more vibrant colors and outlines.
-My eyes were not nearly as agitated as with marijuana.
-No sluggish "couch-locked" feeling.
INDIFFERENT:
-Time distortion
-Fleeting thoughts
-Forgetfullness
BAD:
-Pulse increase
-Slight paranoia
-Slight motor dysfunction
-Tightness of throat along with dry mouth
-Slight agitation, made me a little more "on edge"
Forgot to mention just after the one friend's little falling over episode as I was walking to get into bed my ankles became very weak, the feeling you get in your hands when you've just woken up and you try to grip something really hard. I almost fell over but it was just for a second. In bed I felt a little dizzy and unbalanced, but my bet is that was also psychosomatic from seeing my friend lose control.
Again, sorry for such a long post, but I figure more detail can only help us share our experiences with this seemingly uncontrolled and mysterious blend.
