Mr.Happy may not be as potent as some of the other products from same company, but it sure gets the job done none the less. I find that with other products by the end of the first or second week I’m using more than generous amounts to get the same desired effect as the first couple of days. MR Happy doesn’t follow this rule at all. I’ve been using it for about 2 weeks and still find that I only need the tiniest pinch to get the full experience. I expect my 4 gram order to last me through the month. Effects last for anywhere from 30 minutes to an hour and are mildly stimulating but very relaxing when burned.
