Drug Driving & MDMA

(methylenedioxyphenethylamine / ecstasy)

Illegal Drug Legal Limit
MDMA 10µg%


MDMA is a synthetic drug that alters mood and perception. It is most commonly used orally in the form of a tablet, but it can also be snorted or smoked. This recreational drug has no medical uses. MDMA increases the activity of three brain chemicals:

  • Dopamine
  • Norepinephrine
  • Serotonin

How long does MDMA stay in your system?

When taken by mouth, effects start after 30 minutes and usually last about 3–5 hours. MDMA reaches peak concentrations in the blood within 3 hours after administration. It is then slowly metabolized and eliminated.

The rate at which MDMA is metabolised is measured by its ‘half-life’. This is the period of time required for the amount of drug in your system to be reduced by one-half.

The elimination half-life of MDMA is approximately seven hours. So, if you took 100mg of MDMA at 12:00am, by 7:00am there would be 50mg remaining in your system. By 2pm, there would be 12.5mg in your system, and so on… The quantity of the drug will reduce by 50% over each ‘half-life’ period.

Elimination of MDMA from the body is moderately slow. In fact, it takes about 5 half-lives (i.e. about 35 hours or 1.5 days) for over 95% of the drug to be cleared from the body.

How much MDMA before you’re over the limit?

The typical dosage range of MDMA for recreational use varies from 50 mg to 150 mg.

If you consumed 100 mg of MDMA, your blood concentration would peak at 150 micrograms within 3 hours (the legal limit is 10 micrograms). The concentration in your blood would then begin to decrease by half over each 7 hour period. The legal limit for MDMA is 10 micrograms. This quantity is nothing more than a trace in your system and would have, in our view, no impairing effects whatsoever on your ability to drive.
