I basically get as high as usual with them despite the filter, prolly because I actually get to smoke it all and not too much important stuff is caught in the filter. I used to throw away my roaches anyway, so I figure it's worth it for health+better taste (in my humble opinion). I was just wondering about making batches, because I've heard that breaking up weed and not smoking for a bit could make it lose power. I was just wondering if this old song and dance had any truth to it in your experiences. I'm afraid what I've been making hasn't lasted long enough for me to check this myself. It's a whole lot more tempting to smoke on the go if its only a match away.
