my mate has got an ice bong

THC is not "dissolve-able" in water.

i didn't say 'dissolve-able' at all, anywhere
although thc is soluble (2.8mg/1l water at 23 degress celsius)

it get's trapped in the bongs water as it goes through it, not very much but it will trap a very small amount of thc, it is a lot healthier to smoke through water as it removes a lot of tokins, 'delta-9-tetrahydrocannabinol' also being a toxin it will also be trapped
