[Sorry for the megapost - stims. I know this post probably isn't that helpful, but it if you can be arsed to read it, it provides a pretty thorough brainstorm of all the suggestions I came up with for your question without giving a definitive answer lol]
Without looking up sources, I am 95% certain I read somewhere that there has been an ancient pipe/smoking device found with DMT residue. So yes, there are psychedelics in Egypt.... just perhaps not in the present day. Not that this is helpful to you, but it isn't very often I can get that factoid out!
An educated guess: I'd be highly surprised if psychedelics didn't exist at all in Egypt, but it sounds as though there isn't much of an active community. Thus, there is probably a relatively small supply for a small collective of enthusiasts, but they are basically inaccessible to those who don't happen to have personal relations with this small group. In the UK access to psyches is pretty widespread, as is knowledge of common psychedelics (I learned about them in primary school during a lesson where we were provided info on all the common drugs and their effects - they thoroughly failed to make a single one of them sound unappealing, and here I am). I think most people here order online these days, or perhaps get an occasional hook up for acid/dmt through a small time weed or MDMA dealer. However, I've never met a real life big time dealer that sells bulk psychedelics in the UK.
However, there are certain "scenes" where knowledge and supply of these types of drugs can be found. I was introduced to a psychedelic scene in the UK through meeting folk at parties.... went along to a psytrance event, ended up at an after-party, and from that point on it became clear that a lot of the people I met that night formed a collective of friends that I frequently met at similar events and parties (some of these people were directly involved in organising psytrance events, basically all of them were well experienced with psychedelics). If you are able to find a group like this, then you will have little trouble sourcing/trading psyches. I imagine this sort of thing exists in some scale in Cairo, but perhaps the lack of awareness of the populace regarding psyches means I'm wrong...
Obviously this depends a lot on laws in Egypt (which I know nothing about), but it might be worth doing some research into growing shrooms or extracting DMT. I can't emphasise enough how important it is to know the legality of what you're buying, where it's coming from, and what the consequences will be if you get caught - these are all vital aspects to making an informed decision.
EDIT: Forgot to add, it probably isn't worth taking any unnecessary legal risks with growing/extracting (until you have researched every aspect thoroughly, including the legal consequences, and the ease(or difficulty) in obtaining precursors/materials). If you are really struggling to find anything psychedelic in your area and are dead set on trying, why not take a trip to a psychedelic oriented event/festival? This can take a number of forms, psytrance events would be an obvious starting point for your research, but really anything with a strong association with psychedelic culture would probably do. This won't just tick trying psychedelics off your bucket list - it will likely provide an unforgettable experience in an environment where you are surrounded by plenty of experienced users that can guide you through your first experiences and help to demonstrate the true value of these substances. After all, the quality of the experience is down to set and setting - if it's a choice between secretly tripping on some blotter paper sold as acid in a city that has little understanding or respect for the user, or getting the opportunity to be guided by and bond with a crowd of likeminded people out to spread good vibes - I know what I'd choose. Not everyone is able to find friends willing to join them on such a venture, but the atmosphere of these events is one of social acceptance and most people are more than happy to befriend a stranger once conversation has been initiated.
Obviously, this option isn't affordable for everyone and might involve travelling abroad if there truely is no visible psychedelic scene in Egypt. Also, some people might not go for the festival/party atmosphere, but I reckon you'd be better off waiting till the time is right and saving up for an appropriate event rather than risking legal repercussions by growing/extracting. At the end of the day, what's the rush?
Plus, if you do go to a psychedelic oriented event, you might find yourself making friends with someone who can help rectify your swirly drought!
