Yes. I can't imagine living a day without drugs so part of me says no I don't regret a damn thing and I wish I'd have done more drugs and got into them earlier. But many people DO have good lives without drugs or maybe they just drink occasionally or smoke a little weed but for the most part are sober day in day out and it just seems like normal to them. And these people, by in large, have much better lives than I do.
I got into drugs at 14. Real slow and careful as to what I did. Pretty much stuck to just weed and occasional booze with the occasional this or that. Then I graduated high school. A few months later I couldn't find any bud and ended up hanging out at my buddy's trailer trying to score some. At first he wouldn't get me any but finally he got me some weed. Next thing I know his dad offers me a Percocet...and then I started liking those but I couldn't get em all the time so I started getting blow from this kid I met years before. And then came the valiums, and the Xanax and all of it real fucking quick and I was having too much fun to notice or to care.
Next thing ya know I'm a few months from 25 and don't have a car, hadn't been to college in years, got a ton of debt (2300 bucks or so), no friends for 100 miles, haven't had a girlfriend in years (too much drugs to care about that shit like when I was younger). Family has near bout given up on me and I've near about given up on myself.
All for what? So I could see a few funny colors and feel one with the world? So I could nod out while eating ice cream 100 times? So I could pass out after thoroughly embarrassing myself in ways I'm glad I don't remember? Fuck that shit I'd rather have had a life. I haven't learned shit from drugs and cause of drugs I haven't learned shit from life. The only thing I've learned from drugs is how weak and pathetic and selfish people's inner nature is.
I'm not telling you to not do drugs but you can see why I can't tell you everything's gonna be alright if you go ahead. It might be just fine, or it might be the single biggest regret of your life. Good luck dude.
