Sure? It could be bad for you if it’s bad for you, but the factors and reactions are pretty varied. Taking psychedelics is kind of like driving up a mountain - if it’s storming (anxiety etc.) and/or your lights are out (preconceptions, psychosis), you’re more likely to end up in a bad state, but there’s still the chance of making it to a scenic view, and the people who do get a pretty significant (learning) experience out of it.
