yea man i kinda went through the same thing. i didnt smoke a ton, maybe 4 times a week or so and it was fun for a while, but then i just started getting bad highs, depressed, and paranoid like you said. i finally got fed up with feeling like shit whenever i smoked so i quit for around two months, where i maybe smoked once. since then i felt a lot better and decided to give smoking another try. the first 4 times or so were pretty good, but i didnt wanna risk going back into that depressing cycle again so now i only smoke every now and then and im pretty happy.
