01
Hardware quality
Vape hardware should have ceramic heating elements, food-grade resin mouthpieces, and no metal in the airpath. Older 510-thread carts often used cheap atomizers and chrome airpaths that introduced contaminants. Modern disposables like Waxx Barz integrate the cassette and battery, eliminating the swap-cart contamination vector.
02
Oil purity
California compliance requires testing for cannabinoids, terpenes, pesticides, residual solvents, heavy metals, microbial, mycotoxins, and (for some product types) foreign material. Waxx tests every batch against the full panel. The COA publishes to the verify page. Without a published COA, you do not know what is in the cart.
03
Dosing discipline
A vape pull delivers a measured cannabinoid dose. Smaller pulls give you faster feedback. Bigger pulls saturate before you feel them. The first session with a new strain should start with a small pull, wait two minutes, and reassess. Anti-clog and pre-heat features on Waxx Barz help maintain consistent draw.
