Go to your local drugee area and just stand by the station and offer it to people. If you don't want to do that, sell it to a dealer. EG in London its camden, within 2 mins of leaving the station I've normally been offered draw 4 ot 5 times.

But if I were you I'd just save it for a rainy day when your bored. Or if you'r in London you could always give it to me!
