A force actuated injection device including a body adapted to contain medication, a grip slidably disposed over the body, a lock disposed between the body and the grip, the lock when locked preventing movement of the grip relative to the body and when unlocked permitting movement of the grip relative to the body, a needle guard retractable relative to the body, a biasing member biasing the needle guard away from the body, and a resistance band disposed between the body and the needle guard adapted to resist initial needle guard retraction relative to the body, wherein force on the needle guard exceeding a predetermined amount overcomes a frictional force of the resistance band allowing the needle guard to retract relative to the body to unlock the grip relative to the body such that movement of the grip relative to the body causes medication to be delivered from the body.
