The most common you can't taste or smell
Our test strips detect over 600 drink-drugging substances. These four are the most commonly used.
A powerful dissociative anesthetic that causes confusion, memory loss, and loss of motor control.
A central nervous system depressant with a slightly salty taste — often undetectable in drinks.
A potent sedative that can cause complete amnesia — colorless, odorless, and tasteless.
A stimulant sometimes added without consent, capable of triggering dangerous physiological reactions.
