i have been told by a cardiac doctor that my heart is phisicaly fine but my brain has developed a habit of making my heart go fast or tachicardic from sport and drugs. this happened after smoking some herb that i am sure was laced or bad in some way, because it made me get pretty bad tachicardia and made my friend trip out then get rely sic. but the cardiac doctor seemed to say i caant do all illegal drugs but didnt have any objections to legal drugs exept caffene. he was realy narrow minded and wouldnt answer my questions about these drugs (specificaly ayahuasca) properly, he would just say they are bad for everyone.

i am realy keen on going to the amazon to try ayahuasca but want to sort this out first.
so is there some type of doctor or psychologist or something else that will talk about this honoustly with me and understand?

and i live in australia

I dont know the details of your case in sufficient detail, but this did spring to mind:
