Just odd that a light and gradual "G-force" without striking your head (I assume) would trigger such a cascade of neuro symptoms.

I would also have to agree with the other replies. There is a difference in the effects and consequences of habitual vs short term use of THC. I have not reviewed your attached references, but I would wager that these studies involved shorter term use. By the sounds of your original post, my guess is that you are a habitual user. As an aside, a known side effect of habitual THC use is reduced motivation as well as a reduction in an important neuro chemical implicated in mental wellness called serotonin. Sometimes short term relief of certain symptoms is overshadowed by longer term consequences.

Hope this helps
