im 16, female, i smoke with my boyfriend all the time, more often now in the past couple of months and twice in the past week we only smoked two bowls and went inside, we sat around for not long at all then i started to see black spots and got very dizzy, i couldnt sit up straight and felt like i was falling over, everythings gotten very very dark, almost to the point where i could see nothing around me. it really freaked me out, and usually i have a pretty good high other than being tired later.. but this has never happened to me. can anyone explain this? what should i do?
