How Does Ecstasy Affect a Person's Normal Faculties in a DUI?

Question: How does ecstasy affect a person’s system and how long is it active in someone’s system or how long does it impair them after they’ve ingested ecstasy?

Answer: The answer to that question is it depends upon what the dose of that substance is that is actually taken. In very low dose situations, ecstasy acts pretty much like a euphoric and does not have a huge negative impact on the user. However, as doses increase and concentrations in a person’s system tends to increase, the ecstasy, the MDMA, as it’s referred to as far as its chemical reference, can produce a very profound central nervous system stimulant affect, very similar to the amphetamine class stimulants, and those effects can last for hours and can adversely affect the person for quite a bit of time. 

Question: When law enforcement does a blood draw and that blood draw shows the presence of ecstasy, or MDMA, does that indicate that that person is under the influence of MDMA, meaning they are impaired, that shows up in their blood, or does it just show that it is present? 

Answer: The blood test, first of all, would show its presence or absence. If it were present, then one would want to quantify the concentration of MDMA, in that blood sample, to determine how it may have affected that user.

Question: If law enforcement requests urine from a subject that they suspect, let’s say, driving under the influence of alcohol, how long will MDMA stay in their system in regards to a urine collection? 

Answer: As far as urine is concerned, MDMA can be detectable in a urine sample for up to a few days after last use or last influence. So, the urine test does not indicate that the individual is necessarily under the influence of MDMA at the time of driving. However, it does not exclude that possibility, either. 

Question: So, I understand that if MDMA, or ecstasy, is present in the urine, it doesn’t necessarily tell us or a jury that that person is impaired by it, just because it is present in the urine.

Answer: Correct. Not only does it not tell us if they were impaired by it, it doesn’t even tell us if they were necessarily under the influence at all, at the time of driving. The last use could have been a few days before and the individual may not have any more influence or affect and yet, it could still be detectable in a urine sample.
