Heroin will stay in the urine for 3-5 days

About 3-7 Days hope this helps
In urine only about 3 days depending on how much heroin was used.
No heroin can not be flushed from one urine, it goes to the brain.
Heroin itself, will come up in a urine test 3 to 4 days after using. The metabolytes of heroin will be there for a long time and can be detected several weeks later.It takes 30 days to get out of your urine, But one year to get out of your blood.
If you mean would bleach remove heroin from a urine sample the short answer is no heroin is a drug not a bacteria or virus if bleach was added to urine it would definitely not take the heroin out of the urine if it were present.
