True. It takes less weed to get you high, and the high is much more potent. It's like, you don't get that "stuck to the floor" high from smoking from a pipe, you get more of a "jesus, I'm flying" kind of energetic high. The smell is like hay, not MJ, and it tastes like hay too. But, it's worth it.

The only drawback is the price of a unit. But, I have a solution. As a college student, one has to improvise smoking accessories at times due to lack of funds. I wanted to try vaporizing at home (I had done it at parties and such), but i didn't have the $ for a good one (www.vaporgenie.com I highly reccomend getting one of these if you can, or try www.inavap.com). So, I made my own. Here's how:

Take a clear light bulb, hollow out the insides and remove the bottom metal part. Take the top to a water bottle (plastic, Aquafina or Evian, whatever.), just the spout, and duct tape that bad boy onto the bottom of the bulb. Then, screw the cap on the bottle part and punch 2 holes into the cap with a knife or something. In one hole, insert a straw (or a pen, hollowed out, or some tubing from a hooka, or whatever you can find), use the other one as a carb. You grind your weed up, put it in the bottom of the bulb, screw the top on the bottle, heat the weed just until it smokes a little (It's actually a white vapor, that's the good shit, so don't let it condense.) Take a slow, long hit fromthe straw (or pen) and hold it. Then, exhale. I guarantee after 4 or 5 of these, you'll be pretty well fucked.

It's a little McGyver, and you feel wierd doing it, but when you only have an 1/8th to last 2 weeks, and you smoke like I do,this is the way to make your shit last. I was already a bit of a McGyver smoker, so I don't feel bad. Try it out. E-mail me for more specific descriptions or a picture, or just google "build vaporizer light bulb".

Oh, and to answer your question, they are DEFINITELY worth every penny, there is no better way to smoke, both for body and mind. The hits feel harder sometimes, and you'l cough a bit at first, but it's not bad at all. Wurked Fer mee!!
