Like everyone else, I'd be delighted to take it off your hands. But since that's highly improbable, I say smoke it! If you don't wanna smoke it, cook with it. THC is supposed to be a bronchial dilator (from what I've heard). So it shouldn't be what causes the shortness of breath. Maybe you're just hitting it too hard and deep. Maybe you're not relaxing. The smoke is way harsher than a cig and will cause more lung irritation if inhaled too deeply. Maybe try different methods: bong with ice, vaporizer, etc. Whatever you do with it, don't flush it.
