As your tolerance builds you stop getting high.

I take oil orally and haven't been able to get high period, for a long time. It doesn't matter whether it is the finest bud, hash, or concentrate.

Instead, if I continue to ingest, I lose my short term memory and just get more stupid.

Based on my own experiences with tolerance, I suspect if you laid off for awhile, your tolerance would fall somewhat, though never back down to your original levels.
