3 days
It depends on a lot of things like your age, metabolism, weight, height.. but yea, you have a good chance of passing if you haven't smoked for about a month.
1 month
if you are just worried about how long that will stay in your system then you have some problems. I'd worry about the actual crack smoking part! Why would you even smoke crack?
Not before the month's up with that much weed in you. I would NOT risk it.
Tuesday or Thursday? I'm pretty sure it would take about the same amount of time as if it was smoked on either day. 3 days for a standard urine test, 1 month for a blood test, or as long as you have hair for a hair test. That being said, crack is a terrible drug with side effects that just make it not worth it. Just don't smoke it and you don't need to worry about passing a blood test. :)
yes
If you smoked marijuana for a month - then no, you cannot test clean in two days no matter what you try to do.
No.
A maximum of a month.
I don't know how much you smoked before you stopped, but with a 30-day no-weed window I'd say you're safe.
no sir. you are straight.
