alright everyone, thanks for your input. I guess I can call this a learning experience for me so next time I'll be better prepared.
1. 65 is too much for an 1/8
2. Meet in a place where I have time to inspect the weed no matter how hard it is to open the bag
3. smell, denseness, color are all things to take in account
4. white powder can be good or bad or not there at all
5. look for hairs
6. If ripped off, don't call the cops, settle it yourself

Thanks all, I feel like I could smuggle a 100 lb purchase right now
