The tin foil failed after three smoking sessions. I replaced it with an aluminum can sheet (I cut a coke can into a small square and rolled it into a cone).

Why exactly is the pen bad? The plastic does not get hot, there isn't enough time. It's a one hitter (3 seconds tops).

I don't smoke with the vacuum one. I light my one hitter, inhale, then just before exhale I flick on the vac and exhale into it.

I'm so ashamed! I'm almost 40 and I have to hide like a 15 year old living in Nazzi Germany.

I could just tell my wife. Then again I can also shove a cactus up my asshole. Hmmmm.
