As a fellow smoker, I only want the best quality THCA but these days, it could be tough to find a good, reliable one when shopping online. Here are the best ways to make sure you're choosing right when shopping premium THCA flower online: 

1. Make sure they source from high quality farms. 
2. Check how they process their THCA flower. If they don't mention anything about it, chances are they don't give it much thought.
3. Always check the COA for freshness: when it was done, the terpenes & cannabinoids it's made of, etc.
4. Check for anything fishy: product photos, reviews, gaps in COAs.

Bad smokes are all around but when you check right, you'll find the reliable brand you can always go back to.
