How soon after a person smokes crack will it show up on a home drug test?

Some of those substances can be absorbed into your hair, which is a bummer if you don't actually use the substance.

If you're talking about a urine test, I think that it depends on how direct and concentrated the route of administration it is in your system, in this order: snorting, injecting, smoking.

I'd say that with smoking and injection, not that long, as it goes in and out of your body very quickly. A couple of hours perhaps (max 5 in my opinion) depending if you're a bit user. And then, I think it can show up in urine for the next 48 - 72 hours, depending on if you're a bit user again.

This is say, compared to cannabis, which stays in your system for a long time.

The minute you inhale,it takes about seven seconds or less to enter the brain.Since you are inhaling it,it passes through the lung and the entire body through the bloodstream.so almost instantaneous it can be read on a test.You may get away with it if the test is a simple PH balance test and not very complicated.Cocaine can be found in your system for about 33 days before it starts to recede out of your system.Take it from me(i had tried crack back when it was a new thing and stopped the moment i felt it wanting to grab me)Crack cocaine is a very addictive,and physiological monkey to get off your back.I saw my friends go down that road and a lot of them never recovered.you have about a 20% chance of recovering from it,once addicted.My drugs of choice were weed and meth.I got away with doing it and I had very little consequences for using for 20 years.The day I decided to get sober was where i paid the price and lost everything.I have since been rebuilding my life and have been 2 years sober.All I can say is even though you might cheat death for a cheap thrill,somewhere you'll have to pay a price for what you would consider harmless fun.Dont go down the path I walked,your future depends on it!

1 hour or less, Just say no next time that stuff will kill you! As soon as someone feels the effects of a drug it is in your system. Just as food gets digested and gets in the blood stream, so does drugs but quicker as they are injected or smoked which that makes it even sooner!

RIGHT AWAY!!!!!!!!!!!!!!!!!!!!!!!!! AND FOR THE NEXT 10 DAYS
