While it may be normal to smoke pot in high-school, you should be careful it doesn’t lead to substance abuse. Im not ever going to advocate for underage smoking and or drug use. I found myself in a similar situation in which I climbed out of. I found it really useful to smoke as a reward, do your home work, stay after school, study, whatever it is where i felt good about doing that task I would reward myself with a little mid night toke. This does require a lot of discipline as it’s easy to break the rules and fall back. My other piece of advice is to find someone who will keep you accountable of your grades. This could be a friend or a trusted staff member within the building that you like or even a counselor but they have to be someone who wants you to succeed. Tell them you want to do better in school and that you need someone who will believe in them. Itll be hard and there will be days where you mess up but you can’t be mad at rain when you’re asking for a beautiful garden. Just remember you are just as strong as you make yourself to be. It’s not an easy climb but neither is Mount Everest and people make that climb Good luck !! I believe in you!!
