I think you are missing my point; tetrahydracanniboids (THC) stay in the body for up to 30 days longer than it effects your brain chemistry.
Or, to put this in simpler, more familiar terms... it would be like setting up a road block to check for DWIs if the test that they used only showed if you had used alcohol in the past 30 days.
I’m not sure who told you that cannabis causes you to feel “invincible” but that’s just not true.
The facts in this case seem to be open and shut, it looks to be a very clear case of self-defense. The fact that the kid had smoked pot within the past 30 days has absolutely nothing to do with Trayvon assaulting Zimmerman and ending up shot dead.
Had the toxicology report showed meth or PCP, which *do* cause aggression and feelings of invinciblility, I would wholeheartedly agree with your conclusion.
You are obviously unaware that the world does not revolve around you. Drugs affect different people differently, and it is not defined by how it has affected YOU.

I have heard the opposite from people who acknowledge that their present mental impairments resulted from prolonged marijuana use. Including delusions, paranoia, mood swings etc.
