MAPS helps scientists design, fund, and obtain regulatory approval for studies of the safety and effectiveness of a number of controlled substances. MAPS works closely with government regulatory authorities worldwide such as the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) to ensure that all of its sponsored research protocols conform to ethical and procedural guidelines for clinical drug research. Included in MAPS' research efforts are MDMA (methylenedioxymethamphetamine) for the treatment of posttraumatic stress disorder (PTSD); LSD and psilocybin for the treatment of anxiety, cluster headaches, and depression associated with end-of-life issues; ibogaine for the treatment of opiate addiction, ayahuasca for the treatment of drug addiction and PTSD; medical cannabis for PTSD; and alternative delivery systems for medical cannabis such as vaporizers and water pipes. MAPS officials say the organization's ultimate goal is to establish a network of clinics where these and other treatments can be provided together with other therapies under the guidance of trained, licensed physicians and therapists.
