The number of puffs that you can get from a THCP cart is going to depend on the cartridge’s size, as well as the size of the hits that you’re taking. Most 1mL vape cartridges can produce anywhere from about 200-400 hits, but this can vary greatly depending on the consumer. Of course, the bigger the hit you take, the less you will be able to get from your THCP cart over time. But, if you only sporadically take small hits, you may be able to get your THCP cartridge to last much, much longer. It’s up to you.
