Abstract: A method of dosing LSD in treating patients, by assessing genetic characteristics in the patient by identifying polymorphisms of CYP2D6 before use of a composition chosen from the group consisting of LSD, analogs thereof, derivatives thereof, and salts thereof, administering the composition to the patient based on the patient genetics, wherein a 50% dose is administered in a patient with non-functional CYP2D6 compared to a dose in functional CYP2D6 individuals, and producing maximum positive subjective acute effects in the patient and/or reducing anxiety and negative effects. A method of determining a preferred dose of LSD.

Abstract: A method of dosing LSD in treating patients, by assessing genetic characteristics in the patient before LSD use, administering LSD to the patient based on the patient genetics, and producing maximum positive subjective acute effects in the subject and/or reducing anxiety and negative effects. A method of determining a preferred dose of LSD, by determining metabolic and genetic markers in a patient (such as by assessing CYP2D6 activity and/or assessing 5HTR1A rs6295 and 5HTR2A rs6313 genotypes in a patient), adjusting a dose of LSD based on the metabolic activity and genetic profile, administering the dose of LSD to the patient, and producing maximum positive subjective acute effects in the subject and/or reducing anxiety and negative effects. A method of determining a dose of LSD based on an assessment of the presence of CYP2D6 inhibitors.

Abstract: A method of dosing an empathogen/entactogen in treating patients, by assessing patient characteristics before empathogen/entactogen use, administering empathogen/entactogen to the patient based on the patient characteristics, and producing maximum positive subjective acute effects in the patient. A method of determining a dose of an empathogen/entactogen based on body weight, sex, and CYP2D6 activity by assessing patient characteristics of body weight, sex, and CYP2D6 activity before empathogen/entactogen use, administering the empathogen/entactogen to the patient based on the patient characteristics, and producing maximum positive subjective acute effects in the patient. A method of refining dosing of an empathogen/entactogen. A method of predicting future dosing with an empathogen/entactogen. A method of evaluating feasibility of patients to receive an empathogen/entactogen as treatment. A method of optimizing empathogen/entactogen treatment in a patient.
