How long after consuming ecstasy or methylamphetamine (speed, ice etc) can these drugs be detected?
Roadside drug testing technology will detect recent usage of speed, ice and ecstasy. In some cases these drugs may be detected by roadside drug screening technology for up to 48 hours after use, though the exact time will vary depending for example on the amount taken, the potency of the drug (ie ice has a much higher potency than speed) and how the drugs have been taken.
