OH HEY! Thanks for bumping this thread. Rush, I spoke with Dad yesterday. He's only trained in x-ray, CATS, mammograms (one of his specialties) and GI imaging, not MRI, fMRI or the like. But, this is what he said, and I'm gonna paraphrase: What? Dat's BULLSHIT. The doctor is bullshitting them, there is now way you can get a chemical signature from magnetic resonance imaging, they're fucking with this guy's mother, someone's not telling the truth.
There is NO WAY a doctor can tell you that there is THC in the lungs. Outside of a biopsy, the only thing they can do is test blood, hair and urine, and those things will *only* tell the doctor that there is THC in the patient's system.
End of story.
