So i took a weed...

STORY:
SO hear me out, im a little confused about this.
I was at a party, already had maybe 8 standards so a couple of my mates started rolling a joint, 2 rather fat* joints, and just handed it around in a group of 4. Now these guys smoke weed alot, like they have a very high tolerance built up at that point, and I was taking fat* puffs as they said and keeping pace with them. Like we were there for a while took 3 puffs from one handed it on, but at that point the other joint was already passed to you.
I personally didn't feel that *high* but my mates did, they didn't drink as much as me but still had a few, i felt sober really.
And i mean really sober, straight after i went to a club, on now ~10 to 12 standards and supposedly high, and i got in with out a doubt...

TLDR: Smoked alot of weed on ~8 standards, felt sober rather than high.

Q: Is that normal? or do i have a naturally high tolerance to weed?

* Asked them after that night and they said it was a large joint + on the night they said i was taking big hits.
