I, like you, was eventually brought to Buddhism as a result of realizations experienced during the consumption of entheogens (like mushrooms, LSD, Mescaline).
While many who have not had these experiences believe they can be delusional, *it is quite the contrary*, it can really brings you down to reality in a really hard way. It makes you really realize how much of a delusion we can live in, which are created by mental views/disposition.
It is a funny thing however. I cannot say, it does this or that, since it really depends on the individual who takes it. The effects are really not that straightforward and very complex. Again, the effect depends on the individuals disposition, and I think those prone can have a 'misleading' or 'delusional' experience. However, part of the effect can possibly include seeing things on a level more real than the common state.
I notice, however, that in my later experiences years ago, there was less effect, maybe due to realizations becoming part of my experience.
I often wonder whether I would be the same person (or have the same sort of understanding/disposition) without having had those experiences, and whether I am really better off.
One thing certain, is that I sought the same understanding (wisdom, truth, or whatever you want to call it) before I ever had these experiences, and observe that I was seeking these answers from the start.
I think much of this sort of understanding/views and practice (of Buddhism) stems from the ancient Indus Valley civilizations where you can find the oldest reliefs of people in yogic meditation poses, and where also, the 'Swastika', the symbol associated with Buddhism and Jainism originated. I speculate, that from this culture also came the Vedas. Some researchers believe very strongly, that this culture was involved in regularly consuming a drink called 'Soma' which consisted, partly, of the Amanita Muscaria mushroom. Whatever the concoction was, it was regularly partaken of during their 'ceremonies', and was a religious sacrament (just as Peyote is for the Indians of the Americas, Marijuana is for the Saddhus (hindu ascetics) and as mushrooms, ayahuasca, and various other forms of entheogens are for many shamanic cultures around the world.) So without any question: Gotama the Buddha grew up in this culture and learned the Vedas. I think it is not a 'far cry' to imagine that the Buddha may have also partaken in these rituals, or have been introduced to entheogens.
During my tour of India of the sacred Buddhist sites, I visited some of the museums that were adjacent to it. In them are contained some of the oldest Buddhist statues. I was astounded to see that in many of the statues, the Buddha was standing under what appeared to be a giant mushroom. Not one, but several statues. I examined the shape - it was clearly a mushroom. I think the common understanding is that it is an umbrella to protect him from the sun.
In regards to your question. I think your heart will tell you what is right and what is wrong. If things are done with bad intentions, they can have ill results. As the Buddha has said himself: how do you determine whether a certain occupation/practice is good or bad? If it leads to unskillful qualities it is bad. If it leads to skillful qualities it is good.
