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.
My first time getting drunk was with 17 years old, i live in europe. I could have gotten drunk earlier, as many do, but my environment with friends and family kept me from that. I have to say I am very happy to have had my first serious contact with alcohol no earlier than 17 because i was able to judge the implications better.
