last night i got home and before i gave the kids dinner i said let me try the gravity bong again but with some chronic.i filled up the bottle and inhaled it.i was right.i packed the same size bowl as i did of schwag and it didnt get me as high.i will never waste bud like this again.if i would have smoked the chronic in a regular pipe i would have gotten way more high.for the best results use cheap weed in a gravity.
