Dr. Robb is very passionate about two things: 

Good Science. Clean Cannabis.

This is why Dr. Robb has placed a QR code somewhere on each of Dr. Robb Farms products for you to look up the laboratory analysis for that specific batch of California-grown, pesticide-free Cannabis. He wants you to be reassured that each batch is carefully grown with you in mind. Dr. Robb is pretty smart, but he also understands that you don't need a doctorate to understand that Cannabis consumers do not want poison in their medicine.

Feel free to peruse the lab analysis for reassurance that the Dr. Robb Farms Cannabis that you are about to enjoy is clean and ready for consumption. Enjoy!
