Sure, in the real world, there will be trace amounts of THC that didn't get brought up to the 350 degree temp. range, but I can't believe there is enough to measure, let alone feel the effects.
My point in repeating the above quote is simply to help people get the most THC and pleasure out of cannabis. If you really enjoy smoking resin, by all means, do so. It may be pleasurable to lots of folks. But, in my amateur opinion, there is no way that a person will feel effects from THC, because there is none in resin.

Pipe resin would tend to be primarily made up of things such as CBD and CBN. Well... Methinks it is
primarily made up of the same class of substances that caused the cigarette manufacturers to start putting filter tips on their products so that their customers lived a little longer (and purchased more of the filthy things). I have smoked resin before (we were all young and dumb at one point
). I remember my brother asking, "You've seen that <BLEEP> congealed in pipes - why would you want it to do the same in your
lungs?" I didn't immediately admit that I saw his point, lol... But later on I realized that if I spent the day smoking resin, the next day when I got decent buds, I was unable to get as high as I normally would. I came to the conclusion that the fine structures in my lungs had a coating of recondensed pipe resin on them. Thinking back, I believe that my effort to "economize" by consuming something that I didn't have to pay for backfired in that I'd consume twice as much cannabis in the next day or two out of hopes of getting a decent effect (and duration of same).
Anyway, back on topic... For "glassware," I generally just put an amount of regular table salt into the pipe/bong-stem/etc., then add a good amount (less than 50% of the inner volume of the piece being cleaned, but not
substantially less) of isopropyl (aka "rubbing") alcohol, cover all the holes, and give the piece a good long shake. If I have been lazy and allowed the item to get "nasty," it'll take a few times to get it really clean. I prefer 91% isopropyl alcohol, because there is less water content in it than 70% and there isn't much price difference. Unlike water, the salt
will not dissolve in the alcohol. The alcohol plays its part in dissolving the yuck and the salt acts like a mild abrasive to help break it loose from the glass/etc. <SHRUGS> It works for me... Out of all the methods mentioned in this thread (and elsewhere) for cleaning smoking devices, I think this one works the best - cleans great, nondestructive (as long as the item doesn't fly out of your hand when you're shaking it), doesn't require a great deal of effort, works fast, and I don't have to walk into a smoke shop to pick up the two items I need (being permanently afflicted with paranoia, lol, I'd much rather be seen in a grocery store than a smoke shop). So that one "gets my vote." I'll do a hot-water rinse after I'm finished to remove any traces of the alcohol and salt.
But, really, any method that works for you, doesn't harm your smoking device, and doesn't leave behind toxins ought to be fine.
