It's said that a bong WITH water actually works as not much DMT condensates. It's said to compress the smoke so you can inhale more in a shorter time period, which is crucial.

What do you want? Test out the outer realms or try a breakthru? For a tryout dose I'd recommend ~25mg. This should produce Open eye Visuals as well as very colorful closed eye visuals.

It's said that you need 40-50mg for a breakthru and let me tell you how crucial it is to smoke as much as you can with the first minute. The reason why you should take sloooow hits is, that the DMT gets absorbed by your lungs while you are smoking. Otherwise you'd go like smoke...wait 15seconds...take another hit....wait 15 seconds and so on. With slow tokes you can save some time, I'd say at least 10-15 seconds.

Then you can take 3-4 hits before you can't figure out where to place your lighter.

Don't be afraid, just try to accept the experience as it comes. I havn't felt a bad spirit or something (yet) and even though it'S said that the spice can sometimes cause very frightening experiences, at least the vibe I got was very friendly, euphoric, phantastic.

Just prepare to be amazed
