IVs are different to what you are describing. An IV is a needle used to insert a cannula, the needle is then taken out and a little tube sits in your vein. This is dressed and kept in your vein with tubing attached. A syringe must be attached to the tube to inject any meds into your vein.
Drug users simply use a needle that they guide right into the vein and then immediately withdraw after shooting up with a syringe. It has to be the right kind of syringe that is long enough and the right thickness to entire into the vein.
Insulin needs are subcutaneous needles, meaning they are very short needles that only enter into the subcutaneous tissue, or a fatty layer of tissue very close to the skin. They do not reach muscle nor are they injecting into a vein. Only certain medications (such as insulin or blood thinners) can be given via this route. Giving a non subcutaneous med through this route will cause problems such as pain and swelling, but the medication would not be delivered properly and will likely not have the desired effect. Fentanyl like medications are not meant to be given this way.
IM, or intramuscular injections are given through a longer needle the is going to get to the muscular tissue, deeper than subcutaneous. It does not deliver it into the vein, it delivers it into the muscle. Again, only certain medications can be delivered this way, such as vaccines. Giving a medication that isn't meant to be given this way is going to cause problems but not give you the desired result.
Without proper knowledge about what you are doing this is a method more likely to cause problems than anything. Everything I just mentioned doesn't even get into thinks such as needle gauge size and the likes. Just because it is a needle doesn't mean it is what you are looking for.
I decided to reread your whole comment much more carefully.
I know about needle gouges and sizes. I have gotten blood work done from a vein in my arm multiple times a year for most of my life. my veins have always been very apparent and very visible. As well as also being larger. I know this makes starting an IV easier.
I know I have to use more than just any needle. I know about subcutaneous and IM, and that IM too can actually fail to give me my desired result. This was the Route I used that apparently was half the reason why my ctb failed.
and I know that IV refers to the needle with the cannula as you said. They often use a butterfly needle. 'IV' is just often used to refer to this route.
The only times IV is used regularly on a person that I know of is bloodwork like I had and in-hospital medication and drip bags.
I can promise you I am not referring to a drip bag or continuous IV for my application.
I am just choosing IV because it has a 100% bio availability rate, as well as instantaneous delivery (the most out of most routes such as subq, im, rectal, snort, etc.) Which obviously makes it the most fatal, which we want lol.
I see no difference between drug users 'shooting up' as you described and starting an IV on myself (like with bloodwork) both are IV as they channel directly into the vein. But you let me know if there is.
I was thinking maybe it was better to start a cannula on myself than to shoot straight up because I might not deliver enough medication to die. All that cannula is going to be is the exact same as a blood draw but quickly injecting something instead.
So yes, I think I know a lot of necessary details already and when I google videos intended for nursing students, it seems learnable to me. And I am not trying to safely deliver a medication, of course. It can be rudimentary.
And I'm really tired right now because I'm tired all the time from being continuously sick so maybe im forgetting things, but I have had conversations with users that are drug users and users who say they are in a medical field, Who say they think I can do it.
Perhaps we really just misunderstood each other.
This thread itself was created to see if I could save costs by purchasing a kit intended for students instead. Now I hope I've corrected myself a little, and that you see this message.
don't see how now that IV is not a great choice... So I hope you reply and I hope you agree with that.
Otherwise, idk.
i'm sorry about all that. No hard feelings I hope.
