You have to be careful not to break the glass parts, but putting a bit of ice in the water pipe can make the smoke a lot cooler. I never noticed a significant difference in temperature between a regular pipe and a water pipe with room-temperature water. Burning-hot steam does not feel good on the throat!
A vaporizer is probably the best choice for inhalants, because the THC gets vaporized and the leaf doesn't actually burn.
I don't smoke anymore, because I never know when I'll get called to sing--and I like to practice with my voice in the best possible shape.
It also gets expensive!
