Take his advice. Just burn a small amount before smoking it.

Some weed has natural smells of what you described. Maybe not a strong smell of it, but I have come accross weed that reeked of Cat Piss, very similair to ammonia. Further research showed that there are strains out there known as, simply, "Cat Piss," that is a very strong Sativa that came from the Orange County, if I remeber right.

But yeah, test some first to make sure it doesn't explode or something.

If it's not good, make some hash or oil with it.
