Yes, I am now going into my senior year at a university, Ive been smoking daily since 10-11th grade. But like you said now that im working and taking more tedious courses my smoking has naturally decreased.
But fwi to OP, tons of people like you said blaze and do school and work, ive taken acid over 50 times, smoked way too much ganj, and still people i work with dont believe me when i said that i smoke. Claim, i know a guy, 9th year of school, getting a neuro surgery degree or something along those lines that eats acid and mushrooms frequently and is one of the overall smartest guys i know
