I just took one sweet last night initially, definitely took at least an hour to feel the effects, would be easy for someone to take too much thinking they weren't working. But then I was definitely stoned for a couple hours, had a great sleep.
Same kind of feeling I get if I smoke a joint (which is rare), slightly sick or 'whitey' feeling. But the feeling lasted much longer.
I read it converts differently when digested as opposed to THC from when cannabis is smoked therefore slightly different effects.
