Somehow, I think this thread has one it ought to be linked to:

The majority of people go to the ER with a 'racing heart' and they think they have gotten laced mmj! I would bet 98%! Since, I saw a lot of them and not one was for any other reason. However, there are threads in here of some really odd ordeals some have endured and remained calm and smart enough to know what they were using and how to handle the situation!

I'm sure this will link to a medical thread that will give you tons of info, from all the medical community here! Hope so! We'll see!! :thumbsup:
