Is it normal that after i smoke pot i feel like i'm going to pass out?

You been smoking that kush? I smoke 3 blunts of kush an my brain feels like it's shaking in my head. God I love that feeling. Or make sure you know what's in the weed you're smoking first. Some people lace blunts or joints with coke. Or dip them in embalming fluid (don't ever do that) but It messes you up bad it's called Sherm.

Eat something before you smoke, it will keep your strength up.

Don't smoke pot, asshole.

There's your fucking solution

Sounds like you're not getting enough oxygen in your lungs (and ultimately to your brain). When something, such as cannabis, is burned it releases chemicals like carbon monoxides, nitrogen oxides, et cetera. As you gain more smoking experience, you lung capacity / efficiency should improve.

Helpful techniques: Inhale a little smoke, hold it in your mouth, then inhale again but only inhale air, no more smoke. Also considering using a water pipe (helps cool the smoke) or vaporizer.

All of this, is of course, not from past experience. ;-)

Solution=don't smoke

Yeah those panic attacks are real bad. I did not smoke for a year after I had mine. It freaked me out bad. Maybe don't smoke so much next time...

Does your heart go really fast? feel kind of nervous?

This is called a panic attack/anxiety.

Weed does it to me now. I blazed for 5 years and now i cant touch it because of the panic attacks.
