The legality of THCA pre-rolls from Killa Kush is nuanced and differs. At a federal level, hemp-derived THCa containing under 0.3% Delta-9 THC is legal. Yet, when combusted through smoking, THCa is converted into THC, which is federally scheduled. Numerous states have passed their own laws, with some actively prohibiting or regulating THCA products despite their hemp derivation. Always check your individual state and local laws prior to purchasing or consuming.
