Hi,
i recently discovered that vaporizers are fairly reasonably priced, and they seem to be much more attractive than glass water pipes. time for some questions:
-do vaporizers use mj more efficiently?
-is there any difference between highs ?
-any side effects of using a vaporizer?
-what is the best vaporizer?

the models of vaporizers i found:
