Sometimes, a cartridge can get clogged. When a vape cartridge gets clogged, there will be no airflow and your session is pretty much over until you can fix it. A cartridge is more likely to get clogged on cooler days, as the viscosity of the oil can become thicker when the temperature drops. First gently blow into the mouthpiece to determine if the clog is near the top.
Be careful not to blow too hard, as this could cause a leak in your cartridge. If this doesn’t prove to be successful, please carefully remove the cartridge from the battery and using a hairpin clip or safety pin; gently insert this into the hole of the cartridge. The same can be done with the top of the mouthpiece.
If there’s nothing to dislodge, go for heat. It could be that your oil has simply become too thick from a drop in temperature and a quick blow from a hairdryer from a safe distance could gently increase the heat of the oil in your cartridge.
