Passing a drugs test.

Hey,
Just registered to this website and i'd like to firstly say im amazed at the information here on cannabis, down to the point though.
I've got a drugs test in aproximatly 1months time. MGA approved medical examination. I last smoked about 24days ago, it was about 2 spliffs, and the week before I had another 1 spiff, perhaps a bit more. But I am a very paranoid person about things, I've read that exercising, drinking water and being all-round healthy will help with detox.
My questions are, is there any way of knowing my detox time so I can pass this test?
And is there any solid way of carrying it out of your system faster?
I know detox times vary on body mass etc so here is some of my brief details;
approximatly 70pounds / 10.2 stone
approximatly 179CM height / 5foot9
Healthy liver, organs etc.

Thank you in advance to anyone who can help me :D!

There is absolutely no way to know. Its just guess work. Try and pickup some cheap thc test strips and test yourself to see if dillution is an option for you or whether its better to just sub with synthetic urine.

10.2 stone is about 143 pounds, isn't it?

I was worried that you were 5'9" and 70 pounds :) or 5 stone ;)

A light smoker and 24 days abstinence (and more time til test time)? Sounds like you'll pass. But just to be doubly sure... take a home test and find out! Use your first morning urine.
