Seems like leaves usually smoke nicer if you let them air-dry over a few days. Cut them up with scissors to make them dry faster. Or you can dry them with a bit of heat, but the more you accelerate the drying, the nastier the taste in my experience. When I was a teenager in a similar circumstance to yours I would put a sheet of paper or thin cardboard over the top of an electric lampshade and set the leaves on top of it to catch the heat from the lightbulb. That would dry out enough to smoke in an hour or two, and it was usually no worse than smoking leaves that had air-dried without heat.
Another thing you might want to try: If you have a drip coffee maker, put some trim in the basket with a filter and run hot water through it like you're making cannabis coffee. Throw out the "coffee" you get and then dry out the trim. Sometimes I run two pots of water through it. After it dries, it should smoke a little less nasty, but you'll still get the THC effects if there are any. It also makes the trim a little better tasting for extracts and edibles, IMHO.
