Is this a normal effect of smoking weed?

sounds like you had very low blood pressure. i've been having low blood pressure issues and that's exactly what it feels like when your blood pressure drops suddenly, which could lead to fainting. i've also noticed that if i'm high this is much more likely to happen.

 

In a bong you can definitely get super high really fast and get sweats, shake, get lightheaded. Watch some hashbean420 videos and see him take some monstrous rips and watch him break out in sweat.

 

smoking over a joint to yourself seems like too much for your first time... you probably would been better of with just a few hits.

 

I have never gotten sweats or shakes Little dizzy at times. One time I almost fell to the ground. I was making some food and I zoned out and next thing I knew I was losing my balance and I almost fell backwards, I caught my self before anything I had gone wrong

 

he took a 9 hash hit or some shit like that in this video and you can actually see the sweat lol... Awesome shit
