hello im 18 yrs old.i've just recently smoked weed twice during the span of 3 days from wednesday of which the night i had a really bad reaction to it. the thursday all day i felt ok. friday at about 11 30 i started becoming panicky and had shortness of breath. later that night i woke up in a fright and my heart rate was unusally fast. the saturday i was a bit under as well with an above average heart rate but not as bad as the friday. Now today (sunday) i feel worst again than the saturday but not as bad as the friday with mild panic sessions and an increased heart rate. oh yea i also felt a bt light headed. I would like 2 kno if anyone has suffered/sufferin the same symptoms as me and how long can i expect it to go away thanks...

ps. im not smoking ever again
