Definitely depends on yourself and the strain. I will mostly be able to think extremely abstract and with a very high level of creativity and detail, multi-layered even. Meditation has changed the effects considerably, as long as you're lost in the content of thought, interpreting it as new thoughts, the high is just too overpowering. When you're present you can direct your paradigm and steer the direction of thought waaay better. I guess it all comes down to how self aware you are. I've noticed a general trend to calmer, more tranquil highs as 1) I got older, 2) smoked longer, 3) meditated more and 4) with rising tolerance. Also after psychedelics for some weird reason.
