I asked a question after reading a part of the study.

The study has less to do with using a vaporizer and more to do with using equal amounts THC and CBD.

What they don't mention that I find interesting is whether it was administered in a concentrated vaporizer oil format or, buds put in an old school vaporizer. They also don't mention if participants were new or familiar to vaporizing. I think this could be cause for dispute of the results.

There's a potential that participants that had the combo were more used to vaporizing vs others that just had the thc vs the control.

"Results Both THC and THC/CBD significantly increased self-rated state anxiety compared to placebo. State anxiety after THC/CBD was significantly lower than after THC alone. THC-induced anxiety was independent of anxiety at baseline. When baseline anxiety was low, CBD completely counteracted THC-induced anxiety; however, when baseline anxiety was high, CBD did not counteract THC-induced anxiety. There were no effects of any treatment condition on the EST."

So if you're naturally anxious either way you will still be anxious?

Exactly. Your OP is ignoring the fact that for ~40 years computers weren't considered to have a application or use in the life of an average person by tons of people, yet here we are. It may take 100 years but eventually the average person will have something more powerful than this particular quantum computer in their pocket everyday.
