I was wondering the same from a plant I have. I plucked a small bud and broke it open to check the trichomes under a scope and found something in it that looks just like the one in your pic (was 6 weeks into flower) Unfortunately I'm thinking it couldn't be anything else.
Your post is about a year old so I'm interested in what happened. Was the whole plant full of seeds? Was the smoke it yielded ok? Please let me know
