OK, after having read this entire thread, and having had three experiences with diphenidine on separate occasions, I feel I am finally qualified to post here

. My experience with other dissos is limited to N
2O and K so I can't really compare it to PCP or its derivatives.
First I would like to summarise some "facts" that I've been gathering about this substance:
1)
It is very important to use accurate scales and start with a low dose like I did (50mg) even if you think you have tollerance on dissos. I am very glad I was cautious as 50mg almost sent me to space the first time. Another day I had 100mg which was even more insane and surreal, and another time I had 100mg with a redose of 50mg a few hours later. I had a good time but I don't think I would go further than that as there's no point. This stuff is super strong and can some times feel overwhelming. Generally it hits you at about T+1h, lasts about two hours and after effects last for several hours, during which it might be hard to sleep. Could it be that it does indeed activate the dopamine system, but slower and to a less degree than, say, ketamine? I would be interested to see scientific data on the binding profile.
2)
It has been well established by others again and again that this substance is NOT meant to be snorted so I'm not even gonna try that. If you're a diph virgin, and you're determined to try it, just eat it and don't go above 50mg the first time. You can always do more later, but give it an hour or two first.
3)
There is the potential of some amnesia, although in my experience it's nothing as extreme as benzos. The fact that in the beginning of this thread almost everyone who tried it was combining it with etizolam seems crazy to me. I find it worthwhile to write down notes while on diph.
4)
It is still not clear if it is a good combo with any other drugs in low doses. I remember when I was high thinking "boy, this would go really well with psychedelics, especially the ones that have minimal body load. And indeed others have had success with it. Remember when doing combos to always take MUCH less of each substance than you'd take separately. I tried combining it with N
2O whippets and the effects just added up, with no detectable synergy. Same thing with weed. I can see how it could be disastrous to mix it with downers, especially respiratory depressants, as it could possibly potentiate them, but this is only a theory not based on any evidence.
5)
It can induce both euphoria and dysphoria. My experience personally was one of depersonalisation and distance from emotions, almost as if the reptilian and mamalian brains had finally shut the fuck up and the primate brain was left to roam free of all instincts and emotions. (By the way this was exactly my experience with ketamine, too.) I believe that this is the source of some peoples' dysphoria, but personally I enjoy living like a sociopath for a short while. I think it is valuable (from a psychoanalytic perspective) to get a view of your life while free from emotion, because then you know which of your choices are rational and which are emotionally founded. Some people might feel uncomfortable with such an "unhuman" experience. YMMV. Because the logical part of my brain felt free, at the time I thought I could solve all my problems by just sitting down and thinking about them till I found a solution. I had the feeling that anything is possible, you can be anyone or do anything, YOLO, and all that positive crap! Unfortunately I didn't come up with actual solutions

. I'm not kidding myself, the goal here is not psychoanalysis or personal growth, but recreation; i.e. to have a good time. If you gain some insights that's an added bonus but take any "truths" you gain with a grain of salt as I feel like this substance can also lie to you, if you get what I mean.
6)
It can lower inhibitions, much the same way alcohol or benzos do. You might do things that you normally would avoid and therefore you need to be extra careful and aware of this. A lot of people have already mentioned that you should abstain from facebook because there's the danger of posting things you might later regret. It's not a particularly social drug, although I think in low doses ~50mg it could be fun to do with friends who are also drug-savvy. I had a conversation with a good friend while on 50mg and he said later that I did look a little confused and was talking all the time but unless I had told him he wouldn't be able to tell I was high. There are no visual cues such as dilated pupils or too much perspiration. Still, avoid social settings at least until you're very experienced with this substance.
7)
It is important to keep some drinking water near you and to make sure that your body does not overheat. This is not as important as with, say, amphetamines, but in my experience it is an issue you need to be careful about if you want a smooth ride.
8)
Yes, a moderator here on bluelight died shortly (2 days) after taking diphenidine. The idea that he died
from diphenidine has evolved throughout this thread from a theory to a fact, despite no new information coming in about the incident. In fact this entire thread is a wonderful example of how drug myths get started. We don't know if what he took was actually diphenidine as he thought it was, we don't know why he died two days later, and we don't know what dose he took or if he took something else with it. The fact is that we just don't know.
Mind you, I'm not saying diphenidine is harmless, and yes, sure, it's better to err on the safe side, but all I'm saying is that we just don't know. I feel like diphenidine is reasonably safe since I don't feel much body load during or after the experience and the next day there's little to no hangover. Also I monitored my BP and HR throughout one of my 50mg experiences and they seemed unchanged. But we just don't know.
9)
Don't expect to fall into a "D-hole". From my experience, diph does share similarities with K and others have reported that the experience is even more similar to 5-MeO-PCP but it's not really the same. Generally on high doses you're much more likely to put yourself into a depersonalised, fugue state where you might run off and do stupid things, rather than lie on the floor trying to find the reason why the universe exists as you'd normally do in a K-hole.
10)
Some people have tried IV and smoking. After
15 years of continuous poly-drug abuse I'm still scared of needles, but I'd very much like to know more about smoking it.
Long story short, diph is a fun drug but you do need to know these 10 things I mentioned before you can try it with relative safety.
All in all this is a fun drug to have lying around, I've up to now not felt any hints of addiction and I think I might leave this in my drug collection to be available for whenever I feel like doing it. I noticed a lot of people have hated it, and at first when I read their posts I thought I had wasted good money for a shitty drug, but then I read on and decided to try it, which I'm glad I did. I think a lot of people's distaste of this drug is about the fact that it needs to be treated with a little bit of respect, not unlike salvia, and most druggies are not that organised. I know people who have taken LSD and hate it, while we all know LSD is a wonderful drug that everyone should love. But usually it's people who were like, "yeah, let's do some acid and go watch a movie at the cinemas", then it's the same people freaking out and blaming inanimate substances for their poor life choices.
Crook, I think you mentioned something about
smoking it. You're the defacto leader, president, and moderator of this thread, so please enlighten us! After how long do you get effects? What's the duration like? How do you know if you need to redose? Also, someone please tell us, is it possible that it would be more readily smokable (or snortable) in a salt form? How would one go about converting it? Is the smoked dosage smaller than oral? Does smoking it change the subjective experience compared to oral? As I have purchased 2 grams of the stuff I would be willing to be a guinnea pig and find out what's the best way to smoke it but please share any info that already exists so I don't have to start from scratch.
