Hypothetically you would die. Or hypothetically nothing. Or hypothetically cough like you just swallowed a liftetime of cigarette smoke. Then hypothetically the gear would pass out of your system as a waste.
Hypothetically, it must be the question every one must asks at sometime. Just like the recent post about the panic attack he encountered after his first Injection.
if you injected where you nicked a vein? not much would happen.
if you tied on a tournaqet and shit it directly into the vein you would eithr become very very very sick what we in the medical field call sepsis and could possibly die. Or possibly you formed sme type of emboli and it goes straight to the heart and die. either way you would fuck yourself.
