Resin stronger than weed?

I've been smoking some real choice bud lately. Purps, L.A. Confidential, bubble kush, etc. I just scrapped out a bee-bee sized ball of resin and smoked like a quarter of it. I am super high/stoned and it totally rocks! Has anyone else experienced this? Could the resin mixing from the different strains explain this?

Resin will get you high as hell. But from my experience it doesn't last long at all, and gives me a headache if i smoke more than a bowl or so. Plus the taste is damn disgusting.
