Seems to me you're about 50/50 for a good dilution. The water was good, and 3 or more voids is good, and the nicin can't hurt, but I wish you came here earlier. You would be much better off if you were able to prep a bit more ahead of time, but by telling them you smoked a few weeks ago, your best bet may be to just stick to saying "I don't know...It must still be in me from a few weeks ago, I swear". Although it is lying, so is dilution, so run with it. Tell them to give you another in a week or so and prep yourself well first. Follow the dilution sticky, or sub if you have a clean friend. Let us know what happens. Don't just dissapear after all this, cause I'm curious how it ends up for you, bro. Wish you the best! - Fatal
