The best way to ease your way back into the psychedelic experience is to start incredibly low. Start with the lowest possible amount which would be a microdose. Microdosing is completely different than a ceremonial dose. It's when you take a sub-perception amount of the medicine & it's not going to put you into this space where you feel out of control.
I recommend that anybody first getting into psychedelics start with microdosing to see how they respond to it first. If you are unprepared & especially if you struggle with mental health issues & have been through trauma, sometimes bigger doses can make things much worse. The bigger dosed experiences really need to be handled with the utmost care & reference. They need to be prepared for properly.
The bigger doses can absolutely change your life if they are done correctly, in the right settings, around the right people, at the right dosage & with the right intentions. If none of these things are taken into consideration & you just randomly take it, you never really know what you're going to get.
Everybody responds to psychedelics & the dosage totally differently. Some people are really sensitive & some people have a naturally higher tolerance. Always start with a low dosage & then work your way up as you deepen your relationship with the medicine.
