I feel like the key to modern day Shamanism is to utilize a wide array of psychoactive tools carefully chosen for every unique individual case. For a lot of the population these days, treatments are more about resolving misguided or painful complexes rooted in the past than it is about transcending and gaining infinite wisdom (that comes later after all the lower level healing- premature enlightenment can make unresolved issues even harder to work with). My most commonly used tools would look something like this, starting with the most therapeutic tools and working up towards the more 'Ancient Wisdom and enlightenment' tools: Cannabis, MDMA (and some analogues), mushrooms, mescaline and peyote, LSD, 2Cs, ketamine/MXE/3-meo-pcp, and of course the master level stuff- Ayahuasca and N,N DMT. If someone has a bloated cocky ego and needs a quick fix then some Salvia extract can put them in their place. Otherwise it is more useful in non extract form. I'm sure I'm missing some mentions but That's what comes immediately to mind.
