MDA - MDEA - MBDB

These three substances are closely related to MDMA. They differ from MDMA and from each other primarily in how well one's own feelings are perceived (entactogenic effect), the degree of empathic understanding (empathic effect), and hallucinogenic effects.

Onset of action
MDA: after 30-45 minutes
MDEA: after 30-45 minutes
MBDB: after 30-60 minutes

Duration of action
MDA: 8 - 12 hours
MDEA: 4 - 6 hours
MBDB: 4 - 5 hours

MDA 1.3 mg per kg body weight (1.3 mg x 80 kg = 100 mg)
MDEA 1.3 mg per kg body weight (1.3 mg x 80 kg = 100 mg)
MBDB 1.5 mg per kg body weight (1.5 mg x 80 kg = 120 mg)

Little is known about the risks of mixed use of the individual substances. Nevertheless, the same rules probably apply as for MDMA.

Avoid mixed use with other substances, especially:

• ‍Cocaine
• Methamphetamine
• HIV drugs (protease inhibitors, combination drugs)
• Antidepressants incl. St. John's wort
• ‍Tramadol and other opiates
• Lithium
• Dextromethorphan
• all psychedelics (e.g. LSD, DMT, psilocybin, 2C-X (danger of serotonin syndrome)

‍

• First test a third or half a pill.
• Wait two hours for the effect to take effect before adding more.
• With MDA, topping up is pointless, as it is effective for a long time even in small doses.
• Refrain from mixed consumption.
• Avoid alcohol, consume sufficient non-alcoholic beverages (3-5 dl per hour).
• Take breaks from dancing at parties and get some fresh air in between.
• Take regular breaks from consumption. The body needs time to recover.
• People taking medication are advised to inform themselves about interactions.
