Hi and welcome to PD & BL!
Issues that should not be taken lightly are:
- the fact that you are prescribed valproate is an indirect contraindication i.e. having bipolar disorder and tripping is an increased risk, you would risk getting unstable and going into a manic or depressive episode.
- the above issue is a psychological one but similarly the same problem could arise pharmacologically: the drug might act less well and produce side-effects or other unusual adverse complications.
- in case you were considering it you should never discontinue the medication to be able to trip, that would produce new problems.
When I took anti-depressants, I kept tripping to almost zero - only did it a few times in a couple of years. The majority of that period I wasn't even on those meds but it just felt like the right thing to do even though I absolutely love tripping. Also I took low dose mirtazapine which is theoretically relatively pretty safe but still the principle applies.
What can be said in general is: Using drugs is always risky. If you don't want to run any risks whatsoever you should never use drugs.
You just ought to realize that for you those risks would be increased, and psychiatric medication interactions are notoriously unpredictable in a lot of cases. But just because it is hard to know, imagine, predict or explain what the interaction would look like precisely doesn't necessarily make it that much less of a problem.
