I enjoy my "medical" cannabis for music appreciation but in relatively small doses. Being "wrecked" on the stuff wrecks the music or rather wrecks concentration. Mild sessions wave off repetitive thoughts and other neurotic "loops" and also give the music the same sort qualities we ascribe to tube amps i.e "euphonious distortion." Weed and a tube amp in the chain are for me the best sort of musical symbiosis. Interestingly, if music does not have PRAT I can hear that whether stoned or sober; so I don't think a cannabis high is necessarily an obstruction or degeneracy.
A new discovery for me has been Lion's Mane mushroom extracts. Ingestion of this material improves focus and concentration while also relaxing you. It is like an extremely mild stone, or a very vague stone if you will that can be a bit of an oompf for music appreciation and maybe moreso when taken with a little cannabis.
Lion's Mane Mushroom is wildly popular for enhancing cognition especially so for people such as myself who are entering their "golden years"
