I have these friends who, whenever I go over to their house, we smoke a ton of marijuana. I would like to return their hospitality, but I've never invited them to hang out at my place because I'm worried it would be awkward due to a lack of drugs on my part. I guess I could buy some just for the occasion, but I don't even really know how to go about doing so (when I used to smoke every day, my boyfriend dealt with the dealer) and ... I just don't want to! Can I ask my friends to bring their own drugs, which I will then smoke?

Thanks,
