The actual study sample included 25 healthy participants (age = 34, SD = 11, 7 women) with at least 1 previous experience with MDMA. None of the participants had used MDMA for at least 7 days with other drugs for at least 48 hours, and this was confirmed by a urine screen.

As a conservative measure

To manage the difference between studies in the global prevalence of side effects produced by different drugs, 11 studies that provided <50% ratings on the strength of MDMA outcomes were not included in the analysis. This step meant that the levels of stamets microdose protocol of drug effects were compared in both studies (i.e., the intensity of direct psilocybin effects was 67 ± 19 high and MDMA was 69 ± 15).

Additional title excluded due to significant head movement (mean head movement> single voxel width). Therefore, a total of 13 studies were included in the analysis (i.e., 12 excluded).

An alcohol Breathalyzer

Test confirmed that none of the participants had recently consumed alcohol. For the 13th sample, thegaiavoice.com used MDMA an average of 29 times (± 35) before (range = 1-100) and the median time from last use was 983 days (± 1998) (range = 7-6570 days ). Participants were tested for general health, MR compliance and current mental health.

The tests included a routine blood test, electrocardiogram, heart rate, blood pressure, and a brief neurological examination. All subjects were considered physically and mentally healthy during the study and none had a

Psilocybin

Photography is done in the 3T GE HDx system. Anatomical scan is The Gaia Voice before each scan. These were 3D-degraded gradient echo scanners in axial orientation, (1 mm isotropic voxels).

MDMA

The photography was done at the 3T Siemens Tim Trio (Siemens Healthcare, Erlangen, Germany) using a 32-section head coil. Reference anatomical images were obtained using the recommended ADNI-GO parameters for MPRAGE (1 mm isotropic voxels).

Drugs and scanning parameters

All subjects received two 12-minute fMRI scans with the eyes closed - resting blood pressure level (BOLD) 2 different times for at least 7 different days: placebo (10 ml saline, 60-s intravenous injection) was given on time one. and psilocybin (2 mg dissolved in 10 ml of saline) respectively. Seven of the subjects received psilocybin in scan 1, and 8 received in phase.

The injections were

Given in person by a research doctor inside the scanner. The 60-s infusions started exactly 6 mushroom after the start of the 12-minute scan. Title ratings were provided after scanning using a visual analogue scale (VAS). The effects of psilocybin were felt almost immediately after the injection and were stored for a longer period of time for scanning.

MDMA

Two BOLD downtime scanning sessions were performed during each operating scanning session (operating scan time = 60 min). BOLD scanning of the first resting state occurred 60 minutes after the insertion of the capsule and BOLD scanning of the second resting state occurred 113 minutes after insertion of the capsule.

High subjective effects were reported within 100 minutes after administration of MDMA, usually stamets microdose protocol with plasma t-max for MDMA (Kolbrich et al., 2008). MDMA order and placebo administration were opposed.
