People who smoke weed please look at this?

So I've been smokin' a while but I was talkin with my friends bout times we got high and like what it felt like and I think i might not even be gettin' high when I smoke. I think i might just be gettin like light headed because I can function normally and i usually have a pretty good sense of what's goin on and I never do stupid **** like take my clothes off and run down the street or anything like that so can u guys tell me if i am getting high or what u feel like when u get high? Also i usually have about half of a blunt that has about 1g in it.
