Not exactly a new grower, these guys grow a lot here in Prague, Czech Republic, they're not dealers per se but my friend told me they were growing about a 100 plants in their apartment, so that's highly illegal, there's something interesting about what you said about vaporizing vapor with weed flavor since it perhaps was too fresh and it's that it felt like aspiring pollen, it caused some sort of allergic reaction.?What? I haven't been getting high all these years? Man I am an idiot as well.
If your using a vaporizer the moisture content can interfere with the vaporizing of the cannabis.
I would not buy weed from that guy who likely is a new grower and needed cash, so you can certainly blame him for your low quality product, and you should be honest with him about it. If it were anything else you would return it.
You can cure the rest but before you do read up on the process because if you cure weed the wrong way you can cause the bud to rot.
Good luck and vet all the information you get here.
Only way to know for sure is to smoke it, which I will this week.
