i have smoked my entire male, cept for the roots, its not the same high and i have never gotten a headache, u get pretty high off 1 or 2 bowls, not like really stoned but its good if u dont ahve enuff bud to make a joint or say ur having a ncie session and u need more joints and more weed, mix in some leaves with ur bud (make sure uve dried them) , its a good filler, still gets u that thc but mostly it just packs ur bowls or joints better if u dont got enuff kb
