Hello, I have never cooked with herb, but I do hear it lasts up to 2-4 hours longer than smoking marijuana. I was wondering the specifics of cooking with marijuana: How many grams (or smaller?) Should I put in one cookie (1 serving), how long it will last, the pros and cons to cooking it, and if you tell whether or not you've cooked it by walking into the kitchen (obvious or not). Also, any tips or tricks you may have to help me with this process.
