They're perfect for winter, on account of the wind. If you only hold the flame to the pipe bowl for about two seconds, just long enough to get a cherry, your not burning up the THC. Just don't hold the lighter there too long. That's the whole point of using a torch lighter for weed, you don't need to keep re-lighting like you do with a bic. But, if you burn the weed too long, it's definitely going to destroy it, no argument there.
