Why not just make an apple pipe? If its a metal pen then use it as a stem. I can bet you the smoke will taste much better and you're not inhaling plastic fumes.
Just listen to em, I wish someone was there to tell me to not use my plastic bong. Did not use it very much but I'm pretty sure if fuck me up a little. The only way I would every take a hit out of anything plastic again is if I had a gun to my head.
Why didnt you guys just explain to him why it was bad in the first place, lol. Flamed him pretty hard. Thats like middle school shit.
Ya dont smoke it, like everyone else said go use a apple, potato, ummm a watermelon. anything besides plastic dude. Plastic causes cancer. do you have a death wish?
