The only concerns you should have with vaporizers is that if you are using plant material in a regular vaporizer (volcano, vapor box, etc.) that it's dry enough and the it's ground up enough to properly vaporize and that you also don't fill up the chamber to the max cause you need proper air flow. Also the temp has to be turned up. Now it's been proven that THC vaporizes at about 200C (392F). But I've found that having a vaporizer that gets up to at least 450F is recommended as you might like a hotter temp, so the volcano is one of the few I've seen that actually can get that hot. Most go up to 400F and that's it. If you have concentrate, such as hash (full melt preferred) or wax, I've found 392F works just fine.
