cocaine 4 days.

…it takes blood about six weeks to cycle through- if memory serves me well…absorbtion or excretion is likely during that time, but in regards to your question constipation and other variables, i would imagine, could change the outcome…

my answer was assuming he was asking for a drug test.

about a month depending on how heavy of a smoker you are… keep in mind THC is stored in fat cells, if you are planning on using something to help u pass the test you may need a hardier dose if you are a larger person. If you’re not sure if you’ll pass or not, most pharmacies cell at home drug tests. they range from about $13—$20 depending on whether you need the test to test for just herb or additional drugs. Don’t be fooled by people who recommend things like drinking vinegar. It’s true, vinegar can flush your system- but it’s no exact science… you can flush your system too much and deplete the nutrients from your urine, in which case you fail the test because they know the reason your urine is so diluted. Good Luck to you! :)
