How exactly does thc get you high?

I don’t know too much about thc, so I was looking for someone to fill me in on it. What I already know is that it’s similar to opioids in that modulates the release of gaba on dopaminergic neurons, or something similar to that. What I was wondering was what are some of the brain regions/neurotransmitters that are effected and how does that relate to it’s effects.
