1. no..in some cases it does need to be heated but i eat space yoghurt all the time wich is simply adding weed and eating

2. not reely...i heat weed in the microwave all the time and it only starts to stink when you drying lots ov it at once...iv never worried about the smell when cooking

3.i would say a bit more than you would normally put in a joint or bowl per person

4. it can be alot stronger..depends on what you have consumed in the previous few hours..if you have an empty stomach iv been extreamly high from it
