Hello, I was a daily Marijuana user and i loved it i mean i smoked at least 3 times a day. I have had a tough year with my family and marijuana always helped me chill and relax but i smoked that "legal Herb" and i had a horrible panic attack where my heart was beating fast and i thought i was going to die. Now everytime after that when i use marijuana i have horrible paranoia and it feels like my heart just starts racing but when i have my friends feel my chest they say its pretty normal just a little fast. But too me it seems like i can hear and feel it beating in my chest. I'm a pretty healthy kid no heart disease no asthema nothing like that. And i have a normal blood pressure when im not high
