" The jury is still out on that, and there's a couple different approaches here. One that has been gaining a lot of notoriety lately is using what they call "microdoses," so very small doses that would be so small that typically you wouldn't notice any sort of subjective or psychoactive drug effects. There's an idea that by using continued microdosing of LSD or psilocybin that you may have enhancement of mood or memory function over time.
