The newest and latest generation of home drug testing, at Rite Aid is the 3-panel Teensavers Home Drug Test Kit.

The 3-panel test screens for marijuana, cocaine, and methamphetamine.

The kit, with the most up-to-date science detects marijuana with laboratory accuracy. The cut-off levels are among the toughest, and maintain government levels.

Cheaper import brands sold online and through lesser reliable stores may not give you the accurate readings you need.
