Could my Antidepressant be Interfering with my Cocaine?

So, I had to share this little gem with you all. I went on http://www.druginfonet.com to see if shaky hands were common while on the antidepressant Wellbutrin, and got to see this little nugget, posted on a forum by an anonymous crackhead:

Question: I know that crack isn't recommended, but the question needs to be asked, so we can assume the warnings against the crack itself are already covered. I am taking 150mg of Wellbutrin per day and I want to know how crack interacts with the drug. I know that both deal with dopamine, but are they both doing the same thing, or are they creating opposite affects? I've only tried crack a couple of times, but when I did, my normally slow and very quiet heartbeats became so strong I could feel it with my hand and literally see it pounding below where my ribcage meets. I also experienced a momentary loss of breath as if the oxygen was taken out of the room. Is this because of the crack itself, or a reaction between the crack and the Wellbutrin? Others didn't seem to have the same reactions. I'm also taking Estratest and Synthroid. My blood pressure is typically low and my pulse, even during exercise, barely gets above 70. I can't seem to find any info on this matter, so any help would be appreciated. Please do not post my email address. Thank you.

Answer: There are no direct studies on the interaction of Wellbutrin and cocaine. Both would increase the risk of seizures. As to which is causing the heart rate, I would assume the cocaine. But, there is no clear way of knowing without taking each independently.
