I don't know if they have this in the states, but I'm assuming they do. But what if you got a bag of salvia or any type of those herbs, and just put your normal weed in those bags when you carry it on your person in small amounts. If you were going to pre-roll joints, just toss an empty bag in your pocket. Boom. Other than a stoner, or a cop trained in the different strains of bud won't know the difference and unless he has a stick up his ass will leave you alone. Thoughts?
