For Bongs... Water does not have any fat or anything that absorb any thc at all. Only stuff like milk, butter, and alcohol would do that. It is debatable that there are SOME types of cannabis out there that can actually be absorbed in water. But you most likely should never worry about water taking any thc.. if you're that damn paranoid then go drink bong water and gain powers no man would believe.
Bongs get you really high because you inhale a lot of clean smoke and it feels really good because it's much healthier. Has anyone ever tried Hookah tobaccco without using a hookah? It's fucking HARSH! Same with pipe tobacco. But use water and it's very tasty and smooth. However, I always thought water only made weed taste and smell really sour, so that's a negative for bongs.. Or maybe its because of my metal mouth piece the smoke goes through that makes the metal and even the smoke taste and smell really sour.
Therefore, I highly recommend never to use metal. Glass ftw. Actually, I'm gonna make a thread about that later..

It is definetly factual that joints and especially blunts get you higher because joints are usually made from hemp which is weed so it's like smoking weed in weed.
Blunts really get you high because blunts are made from tobacco, so you get a baccy buzz and whacky baccy high - mixed. Blunts and joints make you take in a lot of smoke too cause they make so much smoke(especially blunts) that it's easy to get pretty high from them.

Pipes are really good for conserving weed as you can take a nug and burn it until there is absolutely positively nothing left (same for bongs or anything that isn't wasted in paper anyway) It highly depends what your pipe is made from that affects not your high but merely the taste of weed. I prefer glass and wood (glass ftw), but metals seem to make weed taste funkier and smell worse.
fuck it im making a thread.

vapes? never tried em but damn do i want one. I like how you can take vaped up weed and save it for cooking. Insane. You could save a lot of money that way. Your health as well.
Of course no one has one cause they're kinda hard to find but mainly because they're really expensive.
