The right dose i would recommend? None. Quite dangerous, you can overdose on it as it contains dangerous alkaloids and either way the trip isn't the same as LSD or Shrooms, it's in the deliriant catagory of hallucinogens. Also it isnt like Shrooms or LSD in that with them your aware your tripping, Datura leads you to believe that infact you arent and whats happening is really real, until you come out of it.
