Roll A Few Spliffs
Spliffs are a great way to make the most out of your bag. Rolling dirty will keep you riding dirty all day. You'll need some tobacco and some papers. Here's a tip, hit up a coffee shop and bum a cigarette from anyone dressed in black sitting outside, you might have to sit through a conversation about capitalism or the government but it's worth it for a couple of free smokes. 1 cig = 3 to 5 spliffs.
Bring Your Own Supplies
If you're going to part take in any of the 420 festivities bring any supplies you have. You may be short on cash or nugs, but you can still contribute a lighter or rolling papers. Nobody really wants to take a hit out of your old raggedy pipe. Papers will run you a couple bucks. Check your couch for some loose change.
Nothing relieves cottonmouth like a nice crisp beer. Head to your local grocery store and pick up some of that good ol' bottom shelf brew. Beer can be used as currency. Pro tip, look in your local newspaper for coupons, or hit up Rite Aid or Walgreens for deals.
Find A Pack of Stoners
If you really don't have any supplies, find a group of stoners and make some new friends. Pro tip, Rasta colors and dreadlocks are a dead indicator of such folk. If none are in sight, just follow your nose.
If you come up on a burn circle and don't have anything to contribute, just offer some good vibes and wait your turn. Beggars can't be choosers, so just wait your turn.
There's no bigger bust than getting the munchies when you're away from home and your wallet is dusty. Food at any resort is going to cost you some serious bucks. Bring a couple of snacks to hold you over for the day. And forget the granola bars, those will just make you thirsty.
