A vaporizer apparatus is provided. The vaporizer apparatus includes a cartridge body and a child resistant device. The cartridge body includes an activation button and an inhalation portion. The inhalation portion is operable to allow a user to draw vapor from the cartridge body. The child resistant device includes an outer cap and an inner cap nestled within an inside chamber of the outer cap. The inner cap is coupled with the cartridge body to prevent access to the inhalation of the cartridge body. In a locked configuration, the outer cap and the inner cap are disengaged such that the outer cap is freely movable independent of the inner cap. In an unlocking configuration, the outer cap and the inner cap are engaged with one another such that movement of the outer cap detaches the child resistant device from the cartridge body.
