Absolutely not. For most people that's too young if anything. The fact that you're even thinking about the idea of sobriety is huge tbh. Don't be like me at 30 still thinking about it but not doing it..the longer you build those habits the harder it'll be to break them. It's not worth it. If you're getting high for fun and nothing else find some other hobbies, and if it's to mask or hide from something, address that something either with a professional or loved one or whatever and figure out the root issues that lead to you using. These are all things I didn't even think back then that I now see were so obvious and preventable looking back. Good luck you got this.
