Is there a safe way to ship amounts to another state without detection. Even thc-c

If it isn't legal in the state, there is no way to safely (let alone legally) do so, neither is it condoned.

So annoying. People like this are what ruins the legal cannabis industry in CO -_-

Step 1: Package in plastic wrap. Step 2: clean packing with bleach water 1tbsp/gallon. Repeat steps 1 & 2 - 3 times. This will eliminate any smell. Ship non USPS. Done.
