drug induced psychosis or bipolar?

i'm trying to figure out if i have drug induced psychosis or bipolar? ive been diagnosed with bipolar. the thing is i can relate to the depression of bipolar. but as far as my manic episodes go they all seem to be spured on by smoking marijuna, drinking and antideprsants. so i wonder if i need meds or not or wheather if i didnt smoke pot i could avoid episodes and not be bipolar. im currently on lithium. i've had 3 episodes in 2 years and they all where drug induced, at least it seems. the first when i was binge drinking for 2 weeks and acting manic. the second one i was on antidepressants (without a mood stailizer) and the third time i smoked lots of marijuna prior to episode. could i have a drug induced psychosis or does that still seem like bipolar?

I think you are experiencing some sort of psychotic breakdown due to the mixture of illegal drugs and your medications.

During the winter I learned the hard way not to mix simple cold medicine with my meds. I found myself in all sorts of psychotic breakdowns. I can imagine if you mixed certain illegal drugs and your meds what would happen?????

You need to start reading your medications warnings.
