Massive opioid fent OD followed by hemlock poisoning?

[heyismeman]

I was considering 3g of fent boofed immediately followed by hemlock tea? Hemlock is supposed to paralize breathing, and so is fent so I figured with fent I'll be unconscious followed by hemlock

Hemlock is not in the news that much, so probsbly not a "Top 10" method.
