I've done a good amount of searching on this forum and others to learn about the mescaline harmala combo. I understand it's generally considered safe and potentiates the mescaline by a factor of 2 or 3. It apparently also changes the experience. What I haven't seen mentioned is the effect harmalas have on the duration of mescaline. Since it already lasts all day, I'm just wondering if adding harmalas would push it even further. I'm also curious how long mao inhibition from harmalas lasts. Anyone with some answers would be greatly appreciated.
