I have smoked a good amount before. One time i smoked, and i know it wasn't laced because i smoked it before and my heart rate went up to around 200. I was hospitalized and they tried to convert me with adenosine twice but it didnt work. My heartrate gradually went down after 9 hours, however i was in tachycardia for a whole 8 hours. I had an EP study done and they didnt find any SVT and said i had normal conduction. What could have caused this? I have had some rapid heart rates after this for no apparent reason however they go away after around a minute.

As you know, a heart rate of 200 beats per minute is abnormal. You don't give your age or past history. Nevertheless, your history indicates that your heart rate did eventually slow to normal. I appreciate that the electrophysiologic study that was done did not reveal evidence of a supraventricular tachycardia, but that does not completely rule that out as the cause for your tachycardia of 200.
It would be of interest to determine the basis of your short episodes of rapid heart rate, and hopefully a 24-hour or 48-hour electrocardiographic monitoring (so-called Holter monitoring) would reveal the mechanism. From your story they may be short bouts of supraventricular tachycardia. If the Holter study doesn't catch a bout of tachycardia, the use of a small diagnostic loop inserted under the skin (a relatively simple procedure) could be helpful.
Please keep in mind that I am unable to diagnose medical conditions online.
