The way I see it there is no way in hell you are going to get 30 doses out of only an 1/8 ounce of good herb. For edibles the dose is at least a grams worth of extraction or cannabutter for me and pretty much everyone else I've ever heard of in my entire life, At least... You can go 2 if your looking to get really stoned or smoke a lot. So you'll get like 2 or 3 or maybe 4 doses out of an eigth of herb. Not a cold shot in hell that your getting even 15 let alone twice that much. Unless master wu has special powers. Lol.

You could probably get 30 good doses out of a full ounce.
