1st hand experience: smoking RESIN WILL FUCK YOU UP, not in a good way either. If you smoke a lot of resin be prepared for the worst lung oysters ever, a NASTY ass taste in your mouth constantly, and very detrimental effects to your lungs. I never have had oysters untill I toked a few bowls of resin, but after hacking up chunky black tarry shit, you'll realize resin is not worth it (for the horrible buzz you get)
