Most pens turn on with one, three or five clicks. Others require only a draw. All after the above mentioned charge.
I would think you need to charge it first
Press it 5×
Hold down button until it starts to flash and inhale
If its charged just inhale and it should light up.
Most common is to press button 5 times until it flashes. If that doesn't work it's likely a dud, they should be cool about an exchange if you have the packaging.
