i need advice

i have been smoking almost every day for 2 years at a time where my brain is still developing. i am scared of the long term effects of weed and want to know if anyone regrets smoking through school? i want to have a future but i see how much my work ethic goes down when i smoke and i see my memory starting to fade. i am very scared and i want to know genuine advice from people who've already been here. if you could go back would you stop being basically permastoned while still having so much ahead? i would never stop smoking completely but if i had to i would. any advice on how to even ritualize smoking would also be appreciated!
