i smoked for 5 years every day, started when i was 16(since 2019) and i quit in september 2024 because i began to have really bad trips i thought i was gonna die of a heart attack. Truth be told i was mixing with apmhetamine, alcohol, mdma etc for whole 2023/2024 but it was fine and in september last year i began to have anxiety attacks after smoking not even one whole joint but i used to smoke 10 joints a day since 2019 i read online it could be sensitization i really wanna know what happened because im 22 and many people around me were lot older and had no problems with smoking, could it be that i abused in 2 much? in september my friends took me to hospital because i thought i took too much amphetamine and drank too much i had few joints, few lines and about 7-8 beers, there they gave me something to calm my heart down(havent told me what). Day after that i smoked and i was fine, but few days after i smoked with friends and i thought i had to go again because my heart was racing crazy, barely calmed down few hours later, after that i tried for few times same shit again, feeling like i couldnt breathe and racing heart(i took 3 hits) and i gave up. I went from 5 years smoking 10 joints a day to "cant even take a hit", never thought this would happen, currently sober for 4 months but i have cravings every now and then, any thoughts on why this is happening?
