Why didn't she get high?

So check this out...

I bought a baggie of some good shit and split it with my best friend . Now, she's telling me if shwag was a 1 on the 1-10 scale, the shit I got her was a 2.

How is that even possible? I would have scored it a solid 7.5. It wasn't the best but it was far from the worst. It was like mid grade kind bud.

I've been smoking for over 10 years, most of that daily. So, I have a very high tolerance. I'm not the kind of person that gets stoned off shwag.

Has anybody had any experience with not getting stoned off kind bud?
