Heroin leaves your system very quickly. On the safe side I'd say a week, but some reports state that 12 hours is enough to test negative for opioids since discontinuation of use.
4 to 6 days. This can very due to strenght of substance, how much and how often you use and body weight/mass/fat %.
it usually last 3-5 days after ingesting
the drug would stay in your system for 10 days.
Drug use is life abuse!
Three days, same as snorted or smoked cocaine.
That would depend on many factors - how much you smoked, your metabolism, body weight, activity level, etc. See the Drug Detection Times link.
it needs15 days
How long has it been since you smoked before Wednesday?
how long will one hit of herion stay in the blood
28 days
If you been smoking for 10 years but you stop for about 30 days it will clear out. it doesnt matter how long you've done just how long you have until your drug test to clear out the marijuana
You should be clean. THC stays in the system about 30 days average - and it only goes down with ppl who have less body fat.
If you smoked a joint once, it will take a few hours and after that you will be fine.
For a month. The amount you smoked doesn't change the fact it is there.
