Peace.
Basically searching for a technique/mantra or rune to feel a high, or get a visual change as psychedelics are able to induce.
Meditating on your third eye for 1-2 hrs, breathing energy into it until it stays open on it's own, has made me feel relaxed and very aware / psychic. If you can't feel your third eye to breathe energy into it then do the vibrations (TH O TH) for a few days. Vibrational chants in general make me feel "different," you could try that. RAUM, THOTH, probably anything will raise your energies and make you feel an energy "buzz". Chakras themselves when they are healthy can be tuned into to focus on a variety of natural, enjoyable energies.
I think some people feel crappy as a baseline, and are looking to feel OK/good, not necessarily trying to depend on drugs or abuse something that will hurt them spiritually. There's so much EM radiation in the air, I have heard that nearby 5g can make it harder to sleep. I think if you had a strong enough mind and soul (aura, energy field) that you could block these things out or overpower them, but I definitely believe in frequencies being able to affect our biology and how we feel (can induce discomfort, anger, depression, and more).. in my mind it's a fact but not everyone is privy to it yet so it can be hard to talk about.
One other thing you can do is try to find a comfortable setting to meditate in. Incense have been used spiritually since probably the dawn of mankind, because nice smells and smells in general can strongly affect one's mood (think of the word "aromatherapy"). Having lit candles nearby can be relaxing too. Also it is important to have your life in balance if you want to feel good and have consistent results with things.. exercising and eating right and expanding your mind each day, getting sunlight, standing on bare earth.. If you don't start your day right then you will probably feel worse than you want to - pleasure is like a reward for growing and taking care of yourself and keeping in balance and fighting off decay.
There is no easy path to feeling good all the time - it comes in waves and I think it has to do with the dualistic nature of the universe. Your environment can affect how you feel though, don't forget that.
None of this is "easy," but the benefit of developing these skills is that they are permanent and don't rely on ingestion of foreign substances. Drugs are not something many people support around here - I myself can't help but wonder if the ancients and primitive peoples and natives were deluded and wrong to be using drugs ceremoniously, or if that perhaps we are sometimes being arrogant to assume that that is the whole, unquestionable truth. It's certainly not good to unnecessarily depend on something, however necessary becomes a matter of opinion in a debate. I had agoraphobia for a long time from being trafficked from a young age and going through torture and "ritual abuse".
Mind control is not mentioned often around here but it is very real, from subliminal to trauma-based (which goes back to ancient times I've learned. There are old caves in France with ancient instructions depicted on their walls about how to do this stuff to people, and it's well known that these things were practiced in ancient Egypt.) It's widely believed that somewhere before the age of 6 certain parts of the mind get formed, and if programming is installed before then it is difficult to break free from. Developing a strong mind and will is hard, arguably..
I have heard that the truth is most often "somewhere in the middle," but, I digress..
