I just smoked and my heart rate?!

Best Answer - Chosen by Voters

What were you smoking. Weed shouldn't do that to you. It may have been laced with cocaine. It's dangerous to have a heart rate that high for a long time. Go to the E.R, stat!

Ahhh a bong:P
So I see you have joined the weed club my friend:D
Now there is 2 main reasons your heart rate could be up:
Number 1 : You are just paranoid about getting caught or that it's going to do something to you so just try and chill man.
Number 2: The weed was cut with something else, if thats the case and your heart rate doesn't return to normal then you should seek medical help.

I've smoked weed before

Smoke more! Get blasted!

If it was me I'd just take a break for awhile until you are back to normal, see how you feel, and relax.
