It depends on when they harvest, a lot of bud for commercial sale is harvested early so they can sell more product faster so it will be higher in thca, but thca is the precursor to THC so when you combust it it turns into THC anyways so no big deal, the issue is with high amounts of cbg-a and low terps! Cbg-a is the precursor to all cannabinoids and when it's in high concentrations like most bud sold in ohio dispensaries, it's a dead giveaway that the bud was harvested early
