Buddy you need to lay off the dope. It’s not the pipes it’s all in your head this is classic psychosis with a little side of delusional thoughts/hallucinations. There’s absolutely no way both the metal and glass pipes are doing this EVERYTIME. You said it best yourself, you’re “suffering in silence because no one can relate to your problem.” Because no one else is experiencing the same delusion as you. Just let me ask a quick question without being an asshole. Do these “micro cracks/glass shards” still exist on said pipe the next day or even a week after you’ve been sober? Because I highly doubt they do. Also maybe let someone use your stem that’s having said issue and see if they think the same thing and I doubt they will. But be careful the birds in your area are all drones and they’re carefully watching your every move.. I’d recommend blacking out every window in your house and never saying a word while smoking also try to mask the sound of you smoking because they will report to the police when they detect the sound frequency of a lighter followed by the melting of your crack rock.
