Hi!
If my asian boyfriend used 4 ecstasy pills within a single 12 hour period about 2 months ago, will he be able to pass a hair test? I know the tests aren't designed to detect "infrequent" users, but what does that mean? Will 4 in one day be detected? He hasn't used any since.
If it can be detected, is there anything he can do to decrease the chances of it being detected?
Thanks!
