You smoked very poorly cured weed your first time. Don't make this a habit or you wont like to smoke at all.
When smoking good CURED weed, you wanna find something that is green but not a bright green, maybe even purple. dense weed is always better than fluffy. Wet feeling is a bad sign, sticky feeling is a great sign. And if it smells bad, then it's probably moldy.
I had some kid try and sell ME a bag like that, you should never. For one, it's bad weed. For two, you're not paying for what it REALLY weighs out to be. Wet weed will weigh more because...well it's wet. If you're buying uncured wet weed and it weighs 3.5 (an eighth) most likely it really only weighs .5 - 1.0 ( up to $10 worth) Now if it is cured and weighs 3.5, then you're safe bet is, you're paying for what you are paying for.
