Like I said previously.... I stopped passing joints a long time ago.... but this would be worth doing for anyone who is about to go to a party soon.
Get some cigarette loads....you know...the gag explosives. Roll not one but two of them into ur weed....one up front and one deeper in the middle. Roll one joint like that and keep it in a separate pocket.
I think ppl will think twice. If you are stingy...
.... you can mix a bit of tobacco to soften the loss.
