So this is why somebody's 2nd hand pot smoke puts me in an aura! I
was walking to the subway last week and some jerk was smoking pot
outside, and I walked through a huge cloud of his smoke and had a
hideous aura after a few minutes. I have had 2 strokes from
prolonged migraine auras, and you can imagine I'm not fond of
them. I ended up in the ER! Because of some stupid creep blowing
his pot smoke all around.
I'm glad it's still illegal. If someone wants to use it in the
privacy of their own home, that's one thing. But to put the rest of
us at possible risk is another.

Here's an article about the study done about pot and bloodflow to
the brain.
