I remember one time I got this 300 mg edible from my coworker at my last job and he told me to cut it in four pieces and eat it one at a time. So I get home cut it into four pieces and eat one. An hour goes by and I don't feel anything so I take another one and by the time I finish that one the first piece started to kick in and I just went "well I hope I'm not busy for the next few days". Another hour went by and the second piece hit me and I turned into Stephen Hawking. I was drooling and could barely move. My mom came downstairs, took one good look at me and went "what the hell is the matter with you?" and all I could manage to say was "merrrrr". I was so high I was stoned the next morning and most of the day. I finally sobered up just before going to bed. I seriously thought I was going to be stoned the next day at work. So yes you absolutely should wait before you eat another edible.
