Very low or zero nicotine vapes?

Hi , just wondering if anyone has any recommends for low nicotine and zero nicotine vapes? Right now i am using 1.8 strength , which i believe is 18 percent ?Basically for now it is just the Vuse gold 1.8, which i think is the above mentioned . Higher than a normal analogue? Looking to go lower but not sure what is available and what is good. thanks
