What Causes Light Headedness And Fainting After Smoking Marijuana?

I sometime smoke marijuana and sometimes I get very light headed and once in a while actually pass out, I mean actually fall down and pass out for a short period of time and then when I wake up I have to go to bed for a few hrs. and sleep it off. This is after smoking only a small amount like two or three drags. Is there a medical reason for this?

We understand your concern.

Cannabis is the active ingredient present in marijuana. Which acts on neurones to produce different effects.one of them is loss of consciousness. That is why you are having fainting spells.

Smoking weed is harmful to health.It has been shown to produce psychological problems. I would strongly suggest you to stop using it.

Hope the answer has helped you.
