how long has your plant been flowering? did you pick it early? you can try drying by placing the bud in a paper bag and shaking it lightly dayly and opening it up to air out for a minute. if you try to dry too fast (with foil under light) the potency will diminish as the thc can evaporate away.

but please let us know what level of growing you are at as that can tell you if that is why it is a short buzz.
