Help IV in the context of suicide.

[nottinghams]

IV has a broad medical use so I'm wanting to know how specifically to set it up for suicide so I do it correctly.
The drug this IV suicide will be specific to is fentanyl or a nitazene, maybe heroin.

Does the IV have to be ongoing or would it be just a quick injection? Am I just flushing my entire fatal dose? Should I use a catheter/butterfly needle? How can I avoid doing it 'too fast' so that I don't pass out before my death?
Please tell this moron how to use iv properly for suicide with an opioid.
