When I first smoke marijuana about 12 years ago, my friends almost rushed me to the hospital coz I cannot breath I thought I was gonna die..I was breathing very fast coz it seems no oxygen that got into my lungs.. It lasted for almost two hours I was too scared to be rushed in the hospital coz my parents might find out.. After that I was too scared promised myself I will never touch weed again..but after 8 years I give myself a try over marijuana see if I have the same reaction again, unfortunately its the same and yet this time I still said NO to hospital my friends are super woried they thought I would die!! Does anyone knows what could this be? I never ever had any allergic reaction in all the human food in this world I could not remember me being allergic to something.. Is this possible that I'm allergic with only one thing in this world --- marijuana?
