24 hours till your drug test? There are only 2 options left to you now:
The first is to listen to an experienced stoner like this guy tell you how he managed to beat a surprise drug test he wasn't expecting 24 hours after he had smoked copious amounts of ganja:
The second option is to pray to God. Pray really hard like you mean it that you will never inhale a drug again and that you repent and will never harm your body in this way ever again, and then maybe God will forgive you and have faith in you and make it happen for you that the drug test will get cancelled or some other miracle will occur to help you overcome this drug test that you face.
This method will only work if you are a Christian and you truly seek forgiveness for your sin. If you are doing this as a quick fix to pass the drug test then light up an ounce of marijuana in celebration of passing the drug test in the first place then you should stick to listening to the drug addict in the YouTube video mumbling on.
