It's night and day. It's also about access. The labs in legal states usually just test for more things. For a while, it was one or two labs plus a Cole extraction companies that were pushing the testing boundaries. Then, relation caught up and pushed the broader testing on to everyone. Then there were managed batch sizes (though these got too small in Oregon). Hemp does not have the same regulations, and unregulated states have way less infrastructure (including access to good labs).

Nobody wants to harm their customers, but it 100% happened in the early days. A lot of harm is/was not immediately obvious. Of was repeated exposure to harmful chemicals. Good intentions are great, but resources and incentives still matter. Nobodyv wants to get hacked, but building a new feature over hardening is what stops you from getting yelled at
