I realize this answer is very, very late ... but may be useful for someone else in future.
Phentermine has a variable elimination half life, which can be anywhere between 16 to 31 hours.
It take 5.5 x elimination half lifes for a medicine to be cleared.
Therefore phentermine may be in your system for up to 170.5 hours (5.5 x 31 hours).
