I did about 5 X pills in a span of 3 days. A few days later I did a line of snow and chest got real tight. Heart rate did not increase so I asked my friend about it. He said I'm getting slight panics attacks due to the X pills. But I only got them when I did coke. I know coke fucks with your dopamen receptors, so I was wondering if the coke triggered the panic attack. He said about after a year of weekly rollin' (he said 1-3 X pills every weekend day for a year) He found that weed gave him panic attacks. Now I don't get the panic attacks from coke anymore, but I saw that if I did some coke THEN smoked weed I got a panic attack. What is the reason for this and will it go away?
