==== Interoception ====
MDMA has been reported to increase interoception, which is the ability to sense and perceive internal bodily sensations, encompassing awareness of various physiological states. This includes recognizing feelings associated with the functioning of internal organs, such as the rhythm of the heart, breathing patterns, feelings of fullness or hunger, and the activities of the autonomic nervous system that are linked to emotional responses.

Ecstasy
Figure 1. MDMA in pill form, aka Ecstasy

MDMA, commonly known as ecstasy or Molly, is a synthetic empathogen that induces both amphetamine-like stimulation and mild hallucinations. MDMA is used clinically in the treatment of PTSD.

Clinical Dosage

Dosage is usually around 0.75-1.5mg per kg and is often performed in the following stages...[1]

1. Recruitment and medical screening. Start tapering of other medicines if needed.

2. Prep sessions 1 and spaced over 2 weeks.

3. 3rd preparation session. Finish tapering off medications.

4. 1st MDMA assisted session 80mg + 40 mg booster dose.

5. 3 week break with a 90-minute integration session each week.

6. 2nd MDMA session 80mg or 120mg plus half dose booster.

7. 3 week break with a 90-minute integration session each week.

8. 3rd MDMA session 80mg or 120mg plus half dose booster.

9. Last, 3 week break with a 90-minute integration session each week.

10. Final integration session.

Mechanism of Action

Pharmacology

MDMA works by increasing dopamine and serotonin in the brain by reducing how it is reuptaken post release.

Neurophysiology

The mechanism of action involves a decrease in activity within the limbic system, a group of structures responsible for emotional responses. Furthermore, there is a reduction in communication between the medial temporal lobe and the medial prefrontal cortex, which play roles in emotional control. Collectively, these effects are contrary to the patterns observed in individuals experiencing anxiety.[2][3]

Effects

Short Term

The dynamic of an MDMA trip is not linear, it takes effect at 30-45 minutes and peaks at 2 hours.
Figure 1. MDMA Time-Effect Curve

When taken orally, MDMA starts to take effect in about 30 to 45 minutes, with its impact lasting between three to six hours. The experience is often gentler compared to psychedelics and is characterised by feelings of enthusiasm, empathy and trust.

Long Term

MDMA is often described as affiliative which is the opposite to dissociative which is and effect often associated with medicines such as ketamine.

MDMA aids in enhancing understanding and management of emotions and coping mechanisms, primarily by augmenting fear memory extinction and rewiring association to trauma leading to decreased amygdala activation. This results in a changed perspective and better processing of traumatic memories. Furthermore, MDMA can modulate fear memory reconsolidation, potentially through effects on oxytocin or activation of serotonin 5HT1B receptors, and improve social behaviors, as observed in animal studies.

Other Effects

Interoception

MDMA has been reported to increase interoception, which is the ability to sense and perceive internal bodily sensations, encompassing awareness of various physiological states. This includes recognizing feelings associated with the functioning of internal organs, such as the rhythm of the heart, breathing patterns, feelings of fullness or hunger, and the activities of the autonomic nervous system that are linked to emotional responses.

Sexual Relationships

It is likely that MDMA increases sexual desire and intensifies orgasm and that dose, ‘set and setting’, and timing relative to MDMA administration make major differences in ability of men to achieve the erectile quality necessary for ejaculation[4].

MDMA has a stronger effect in women

Women are more affected by MDMA's psychoactive effects than males[5]. Women especially have greater perceptual changes, thought disturbances, and fear of loss of body control. In addition, acute adverse effects and sequelae were also more frequent in female than in male subjects. In contrast, men showed higher increases in blood pressure than women.

Coadministration

It is thought that the effects of MDMA might be further potentiated by administration with psilocybin termed a hippie flip[6]. Therapeutically, MDMA is often used first in order to build the therapeutic alliance and increase the patient’s openness to change, leading to enhanced resilience and lowered stress levels. Once further changes were noticed, such as improved self-regulation, less negative self-perception, and increased tolerance to trauma exposure, a psychedelic such as psilocybin was introduced to assist psychotherapy. The deepening of the therapeutic process led to improvement per clinical judgment, without adverse events.[7]

Adverse Effects

MDMA Comedown

There is a wide amount of anecdotal evidence and some scientific evidence[8][9] to suggest that after using MDMA there is an emotional comedown reported colloquially as "Blue Mondays". However, a recent, low powered study found that there was little evidence for this[10].

Toxicity

Overusage of MDMA can lead to neurotoxicity.
