mkayyy, well your almost in the right spot, but I'll just give you my 2 cents.

I also heard that rumor, and it did happen to me for the first 3 times I smoked. Of course, I was smoking shitty weed too. In order to avoid this, just get some really good weed. If you don't know what it looks or smells like, have a friend get some. Good weed makes all the difference. Have fun!
