Another exception is peyote, which is legal to use by members of the Native American Church. Other religious exceptions may be made for other substances, like Ayahuasca. Studies in to the therapeutic potential of psilocibin may eventually lead to enough of a shift in perception of that substance to make it legal for certain limited types of therapy. Then, as was seen with medical marijuana, that may eventually lead to legal "recreational" (ie. non-medical) use.
There could still be a big backlash against all this. I'm holding my breath waiting to see what the Trump administration and their supporters do.
