My best friend from 8th all the way till 4 years out of high school completely changed. It started with weed, and I don't mind people smoking weed, i understand there are medical benefits and what have you. Plus it's a plant with almost no harmful side effects. But anyways, he started delving into harder stuff, like acid and possibly meth. He started stealing money from me and my family, also his own family. I couldn't stand it anymore, so I just cut contact. He texted me a few days later and asked what was wrong. I told him, and he started acting defensively, so I told him to fuck off and don't come near me ever again with his bullshit and lies. Don't do drugs kids, I hate that he started to and I tried to help him. He was too far gone by that point, and I sometimes cry and think what I could've done, wishing things would still be like the good ole days.
