The law on this is what it is. Your opinion as to whether the law is good or bad or off base doesn't matter. The OP wasn't asking about how people think things should be. The OP was asking about possible complication under existing law of the state law legal use of marijuana under certain circumstance.
If you think the laws should be different from what they are, our systems offers you a number of ways to try to change the law. But opinions about whether these laws are right or wrong are off topic for this thread.
