Cartridges taken apart: the hardware itself, meaning the heating element, the wick or ceramic core and the materials touching the oil, what goes into a filling, and how a counterfeit is recognised before it is inhaled rather than after.
This is the product category with the widest gap between what a package says and what is inside it. Thinning agents, unlisted flavourings and residual solvents are the recurring safety questions, and they are questions about the filler rather than about cannabis. Hardware quality decides the rest: an element run too hot degrades the oil it is heating.
Two things belong in every thread. A certificate of analysis matched to the batch is the only evidence about contents that means anything, and a certificate for a different batch or an unnamed laboratory is not evidence. And the legal position follows the extract: in Thailand extraction above 0.2 percent tetrahydrocannabinol falls under the Ministerial Regulation on Cannabis or Hemp Extracts B.E. 2569, in force since 26 April 2026, and nothing may be offered for sale on this forum.
