Weed has one of two effects on me:

a) Nothing, except maybe my lungs feeling a little warm

b) The person I'm talking to is disgusted by me, and anything I do to try to soothe my fears will only deepen their disgust so I have to sit here and not say anything until this shit wears off or I can find an excuse to go home.

I've been told by numerous people I have to just find the sweet spot, but I've tried enough times that it feels like it's either nonexistent or too hard to get just right to be worth it.
