Does anyone know what can be used to dilute hash oil with so it can be put into the cartridges for this type of vaporizer? The oil is so thick I can not get it into the cartridge. I do not want to waste it but the dispensaries in Michigan are on hold now. Trying to refill my old cartridges and I do not want to ruin the oil which is almost like a tar now.....Would Glycerin work and if so how long would it have to set before I could put it in the vap?
