Is my reaction to weed normal?

Four hits is too much for a "lightweight". One puff would have been plenty enough.

It sounds like you pulled a whitey (low blood pressure, pale complexion, physical weakness). It is typical reaction when you've had too much but it's not life threatening. When it happens you only need to eat a sweet treat, like a candy bar, and you'll feel loads better. But it can be frightening when you don't understand what's happening to you and you're high as a kite.

You haven't provided enough details to really assess what happened but I think you just had too much . If the weed was potent in THC it's easy for anyone to have too much especially someone who is a light weight as you put it . I can literally get high off 2 puffs of weed and .. event that's quite a bit for me , from a joint! I have had strange experiences with weed .. it can also act as a psychoactive because contrary to the ill informed belief .. it is . I would say you just got real high because aside from the lungs burning those are all common effects of marijuana and you passing out was your bodies way of shutting off and dealing with it this way . If you want to smoke up again , take one puff maybe two if you think you can .. wait 20 minutes , see how you feel and how your experience is as opposed to the 4 you did off the blunt which was probably rolled thick . I hope this helps , message me if you need to .

^That or you had a panic attack. Weed has an ability to decrease anxiety in some people but certain strains effect every one differently and it could be that it actually had the opposite effect and increased your levels of anxiety.

It was hydroponic weed, right? That stuff is full of all sorts of chemicals, probably as many as tobacco

Do you have any medical conditions that would cause that? Aside from the heart rate, it sounds like you just had too much. However, based the sudden drop in heart rate it sounds like you either have heart problems, or your friend's weed was laced.. Or he could have just measured your heart rate wrong.

Now this is obviously laced, with your heart rate speeding up it's ethier methalipadate or pcp (angle dust).... Did your friends freak the hell out too or juat u cuz u might have a bad reaction to ganja

Thanks guys so much, unfortunately my friend said I am not allowed to smoke around him anymore as he doesn't want a death on his hands, apparently the time before this he measures my heart rate when I was complaining about chest pains and it went from 156 to 52 in under 5 seconds.

Doing drugs isn't normal. Stop it.
