Yeah so the problem with hard opiates is that they'll hollow your soul out over time, and they are actively more addictive the more your life sucks when you start using them. People who have good lives tend to be more likely to say things like "opiates are too subtle/overrated". But when shit sucks, opiates make you feel content. Obviously that's real bad if you weren't already somewhat content with life. When I started using them I felt like I found some sort of answer to everything wrong with me. But my problems didn't go away, I just stopped being bothered by them.
The shittiest thing is that this effect isn't reliable. It's called the honeymoon phase of opioid addiction. Within a few months of active opioid addiction, you'll stop feeling the effects, but you'll still need to continuously use them to avoid horrific withdrawal symptoms.
I recommend LSD, Shrooms, or dissociatives instead. The euphoria can be vastly superior because it isn't this kind of "ultimately contented, but empty" euphoria you get with opioids. Instead you just sort of feel really good about the actual positive shit that exists in your life and around you.
