High Lion ,
Is there something wrong with the taste of what you are smoking ??? If it tastes crappy maybe you could wash it in cold water and filter it through a coffee filter , dry it (quickly before it starts to taste like compost ) and then try smoking it . Suger in a joint tastes crappy , like burnt caramel and i think it makes it burn faster . Putting oils in it would make you cough your guts up . Knaster if its the same knaster that you can get in Germany are just mixtures of herbs and will only weaken the joints . What about skins with tastes in them ? I`ve seen them in shops with licorich , banana , strawberry and other tastes .
