Dry herb vaporizers depend on convection, conduction, or hybrid heating systems to evaporate the cannabinoids and terpenes from flowers. When this system fails, users receive either very light hits or nothing at all. Issues with heating stem from several sources. Vaporizers use a piece of kit called an atomiser to convert energy from the battery to power the heating system. After prolonged use, atomisers become worn out and need replacing. Before ordering a new atomiser, make sure your battery is fully charged and fitted correctly—it could simply be a connection issue.
