In case you are wanting to know which of the numerous designs to choose, I would personally give you advice to purchase the types that will allow the THC to build up within a bag for three large hits. Even so there is also a disadvantage to working with styles that keep vapour within a bag. Similar to a pipe, bong, and so forth, marijuana resin will start to develop within the wall structure within the bags. Even just a small amount of resin is sufficient to lead to trouble in case the bags wall surfaces are allowed to touch together. You know when this happens since the inside walls of your bags cling to themselves, and instead of the bag filling with vapor and air, it is closed shut and you see the vapor coming out of the device itself. If no oxygen or vapor goes into the bag at all, you've just wasted a load of marijuana. I'm willing to offer you a very good suggestion which can help keep the particular resin from developing right off the bat, just leave the top off the bag immediately following use. It's very difficult to suck all the vapor out of the bag, you will have tiny pockets of vapor still in the bag regardless of how metal your lungs happen to be. With time, if you leave the lid off of the bag, this vapor can release from the mouth opening. When you leave the lid on it and there's even the smallest quantity of vapor within, it will layer the interior of your bag and then make it tacky. Before I realized the cap technique, I'd regularly cleaned my bag out just for it to get stuck once more the following day.
