I just talked to my girlfriend (and wife) Amy. She's been an RN for 20 some years.
Here's the straight poop:
Hypokalemia (low potassium levels) are caused by deficient dietary intake, deficient IV intake. GI disorders, diuretics, Hyperaldosteronism (what ever that is), Cushing's syndrome, Renal tubular acidosis, and last but not least: Licorice ingestion!
You can easily pass out if your K+ level drops, many people die from it. Eat a couple of bananas and everything is just fine, fortified orange juice and dark leafy greens like spinach do the trick too.
Now, if the person smoked reefer, got the munchies and ate licorice they may
have something there.
I can see it now: The Licorice Defense! POIFECT.
Hard to believe that cannabis could have any effect since K+ levels are regulated through your urine. Cannabis only effects your gray matter and can (over a long period of use) cause d
amage and acute paranoia.
I have no first hand knowledge of this and wish that Grif would quit listening in on my phone calls.
