Oh man, what a great topic...the first time I IV-ed coke (was actually the first time I ever tried it, and coincidentally was also the first time I tried smack which I IV-ed as well). I did the h IV-ed and then snorted the remaining portion (it was a dime bag), anyways about 3 hours later I did the coke IV.
It was probably one of the top drug experiences I've ever had. The rush is indescribable. The audio effects that you get and hear are unreal. My first time doing it the audio effects lasted a couple minutes, but since then I've done it where they lasted a solid 5 minutes at least. Those are the best times. For those who don't know, the audio effects are similar to that of nitrous. The only way I can come semi-close to explaining is to say it sounds like everything has a "vibrating, tin can, echo" to it. I've also had some pretty strong ones where after I did it, not only did I get the audio effects but then a large portion of my body went numb (well not numb, but that pins and needles feeling), all the way down my arms and legs and my face too. That was probably the most intense coke IV.
How can the coke IV get any better...add some H to it. Before people rant about how dangerous a speedball is, do a little (or a lot) of research before trying it or bashing it. I absolutely love speedballs. I don't do them all that often at all anymore, but when I do, man pure bliss really. Now this is a truley indescribable feeling. One of the best feelings in the world I would have to say, they are always at the top of my drug experiences list. If you enjoy coke and H in general, do your research and then try banging them both (please be extremely careful and ask away with questions before you do it, and make sure someone is there with you, like you should do anyways). You won't be dissapointed with a coke/H speedball.
**Please don't let ace of spades thread turn into a speedball thread, i did not intend to do that, leave it as a coke IV thread, we've seen plenty of speedball threads anyways**
