I have to be smoking weed wrong

Okay so, I have been attempting to smoke weed for over a year now. The thing is every time I hit my vape I feel NOTHING. I've tried four different vapes, I have one that is 97% THC. The thing is I feel edibles and I can only take 5mg, but do better with 2.5mg. I literally greened when I accidentally took 10mg once. Am I smoking wrong?

I inhale, hold for 3-5 seconds, exhale.
