I don’t use drugs nor alcohol, but I just turned 18 and I noticed that a lot of people younger than me (high school age so 14-17 even) use alcohol and sometimes drugs from siblings, older friends, etc.
Did you do that when you were younger than me? I don’t plan on doing so anyway.
Something to keep in mind is that kids aren’t generally allowed to drink in establishments or homes, so they often do so in public such as the park, and when they get caught they often get arrested and have to pay fines which can snowball into never getting out of debt.
But no I don’t touch any substances that impact cognitive ability. I feel as though doing so would make me less myself, and I would never do that.
