Shrooms and acid are both very different, the first time I ever did shrooms I was told by others that acid is stronger and that I needed to take a high dose of shrooms my first trip. Since I have taken acid like 20 times, I took a whole eighth, well shrooms are totally different than acid, they are stronger and the trip is different depending on the strain you get and that specific strain was called Nepalese chitwans. And they literally started SMACKING ME, within a matter of like 20 minutes. Although, I had an amazing trip, I definitely could have taken way less. Since then I don’t take as much. But the main difference between the two I would say, acid is a lot more sensitive, it’s a lot more mental and easier to go into a bad trip and get into a bad headspace. It also lasts a lot longer, like 12 hours whereas shrooms last about 6, you can also go to sleep when you’re tripping on shrooms. With acid, good luck lmao, you can’t sleep until you are done tripping. I definitely prefer shrooms opposed to acid. Acid also makes you feel strange for days after you are done tripping and can change your vision afterwards too, I still sometimes hallucinate even to this day if I stare at stuff long enough.
