Blood test - pass?

[f12button]

I'll tell you a story about this guy named Jim.

Jim has a drug test in about nine to ten hours, tomorrow morning. He needs to sleep, since he has work all day. The method of testing will be blood, other methods are a possibility but blood is for sure.

In the past couple weeks, Jim has done marijuana, cocaine, and LSA. The LSA was atleast three weeks ago. The marijuana was atleast one to two weeks ago, and the cocaine was about a week ago.

The problem is, yesterday, Jim took a small hit off the very end of a blunt (did not get high), and had a little cocaine left on the razor that he rubbed against his gums (and got dilated eyes).

Is there any way to pass the test? Jim thinks drinking a lot, a lot, a lot of water might help. He needs to pass 100%. In Jim's expression: :\

Thanks

Jim forgot to remind me:

He also took MDMA a couple weeks ago.

Well, tell us!

Surely there was more to it than a blood test. Aren't blood tests mostly limited to determining current impairment? The voices in my head say if it's been 5-6 times as long as the half-life of WackyFunDrug since SWIY indulged in WackyFunDrug, there shouldn't be enough evidence of WFD metabolites left to show on a blood test.

The other voices argue drug metabolism is always individualized. Demographically as an 18-year-old, SWIY should process things through pretty quickly. (Even better if you're a male).

The virility of liver and kidneys are important, too. The voices in my head say these organs do their best work when nourished/hydrated properly and not forced to filter out too much crap. This is a long-term thing, though.

Someone is pretty sure there is nothing short of hari-kiri that can radically alter the status of a blood test short term.
