lol like one person even tried to answer your questions....

to be honest i dunno, i don't mess with KB much.... mostly mids for me... so i coudln't tell you... as for the smell sticking on you and hair and all that, i doubt it....

probably your head playing games

no, i'm pretty sure it provides a longer lasting stronger 'stone'...

there are diffrent strains and two main types, sativa, and indica (there is a third, ruderalis i bleive, but you don't hear about it much and i'm not even really sure of what it does if anything, if i'm not mistaken it's usually reserved for hemp products) anyways sativa is a heady, energetic high, indica is the strong, couch lock high.... strains these days are usually a hybrid of the two (i think the usual percentage is like 20% of one, 80% of the other, depending on the strain it could have diffrent effects on you)
