No dude its actually quite a good explanation. Mixing bupenorphine with marijuana gives many people panic attacks. let me guess, you started to get nervous after the smoking, your heart started racing, your body and head got tight and stiff from high blood pressure, and you got really anxious over the fect that you were convinced you were gonna die. thats what happened isnt it. yep, it was a good old fashioned panic attack dude. me and 2 of my friends get them everytime we tried to mix subs and weed. and theres already alot on the internet about subs causing lots of people anxiety, so when you throw weed in the mix, which is already known for its effects of causing paranoia, elevated heart rate, raised blood pressure and thoughts of death, you get a panic attack, which id bet $1000 is exactly what happened to you
