Question

How long does heroin take to get out of you system

Answer 1

It depends why you're asking and also on what you've been using, how much and for how long.  More info please!

Up to 4 days for a clean urine test to be sure (if you are addicted withdrawals start earlier than that and it can take about a week to start feeling better physically, sometimes earlier. Psychological issues are something else entirely.)

(that last one in case you you need it.)

Answer 2

After IV injection, 10-40 minutes.

Answer 3

You didn't specify anything, so I'll be assuming you're talking about one-time use.

It takes 4 hours for the effects to completely wear off, if that's what you mean.

But all of the drug should be completely out of your system and undetectable in urine by the time this question closes. Assuming you didn't do anymore after you asked it.
