The State of Florida vs George Zimmerman: The Trial

We still don't know how the jurors have decided this case - thus far. The odds of 5/7 sounds pretty reasonable at this juncture; nobody really knows.

It was a trace amount. Also the doctor first said it shouldn't have affected him that night, then changed his mind because he consulted someone else. We don't know the information he had that made him change his mind, so I don't give a lot of credence to any of it.

Actually I don't think the jury heard any of it. Pretty sure they were out of the room.

How does Zimmerman overcome all the lies that's been confirmed in court?

Limitations of Drug Tests

Because marijuana stays in the bloodstream for a short time, blood tests for marijuana are usually not used, except in the case of automobile accidents and some roadside sobriety check points. Blood or saliva tests can show current intoxication. However, unlike blood alcohol concentration tests, they do not indicate a level of intoxication or impairment.
On the other hand, urine tests for marijuana metabolites can only show recent marijuana use, not intoxication or impairment, because of the time required between smoking and the metabolites being eliminated in the urine. However, because many employers have a zero tolerance for drug use, most workplaces use urine tests for any recent use of drugs.

How Long Can Marijuana Be Detected?

Some THC metabolites have an elimination half-life of 20 hours. However, some are stored in body fat and have a elimination half-life of 10 to 13 days. Most researchers agree that urine tests for marijuana can detect the presence of the drug in the body for up to 13 days.
However, there is anecdotal evidence that the length of time that marijuana remains in the body is affected by how often the person smokes, how much he smokes and how long he has been smoking. Regular smokers have reported positive drug test results after 45 days since last use and heavy smokers have reported positive tests 90 days after quitting.

Well, maybe, but the reason he changed his mind, seems to be not clear enough to be able to take what says with any credibility. We don't know why he changed his mind,

So it has not been established Trayvon Martin smoked the night in question.

How Long Does Marijuana Stay In Your System?

The effects of cannabis may fade quickly after ingestion, but its active ingredient, tetrahydrocannabinol, can remain and be detected in the body for weeks, and maybe even longer. This shall depend on how the substance is metabolized.

Some tetrahydrocannabinol metabolites have an elimination half life of 20 hours, while others are stored in body fat and have elimination half lives of 10 to 13 days. Half lives may be influenced by how heavy the person weighs, how often he uses the drug, how much he consumes, and how long has he used it. [18]

Retention time of orally ingested marijuana ranges from 1 to 5 days. [19] Occasional smokers can take cannabis out of their system within just a few days. For regular heavy smokers, it will take 2 weeks to a month before drug levels reach nil. Those chronic users, who smoke weed on a daily basis, may still have it in their bodies even 2 to 3 months after their last consumption. [20]

Martin's mother is on the witness stand...

. . . and she is absolutely, positively certain that the yelling on the 911 tape came from her son. The trouble is, Zimmerman's mother and Zimmerman's uncle both stated the same thing just 30 minutes ago. All three are absolutely certain, but at least one of them is wrong. Talk about reasonable doubt!

Why was Trayvon Martin suspicious?

he was black...

I believe Zimmerman said in his 911 call that Martin appeared to be on drugs. And indeed, the doctor who did the autopsy testified today that Martin had THC in his blood. (THC is the active ingredient in Cannabis.)

I must have turned my eyes at the wrong time, did the judge rule of the defenses motion to acquit? I figured she must have as the defense has now started their case and they are now recessed.

As just an aside, that medical guy who did the autopsy was a hoot, not a very good witness for either side or even the court in general. However, Trayvon Martin's mother was a strong witness.

I'm not sure who posted these odds earlier in this thread. Just repeating what I read.

That's not the point. The point is that this was one of Zimmerman's stated reasons for suspecting Martin. The actual presence of THC in Martin's blood affirms this argument of Zimmerman's up to a point. It remains a reasonable hypothesis about Zimmerman's motives other than a depraved mind. And to get Zimmerman's acquitted, a reasonable hypothesis is all that it needs to be.
