If you are not familiar with using and you get edibles - seriously do not take a lot - often new people take too much because they don't feel anything right away and it looks harmless and so they take more of it and they green out and feel really really sick. It won't hurt you but it feels bad (a friend of mine ate two cookies of mine not knowing it was pot and I didn't know she was going to go rummaging around in my kitchen to find them so they were not labeled - she physically felt bad and it freaked her out a lot- so much so that she went to the emergency room where they laughed at her)
