I assume you know that you can't go into a medical marijuana dispensary if your out of state? That being said...

Cheeba Chews is probably the most powerful edible around that has exact dosing. By that, I mean each dose will be exactly the same as the last. They are little tootsie roll tasting candies that I eat half of.

I recommend the 70m Indica. Eat half and it will hit you between 45 minutes and an hour.
