Medical marijuana and recreational cannabis is being legalized in more and more states. Currently 25 states have laws legalizing marijuana in some form and it seems like more states will be allowing the sale of marijuana as they look to tax the sale of cannabis products. Four states and the District of Columbia have even legalized marijuana for recreational use. Whether you are a producer or processor one piece of equipment that is required is a digital scale to weigh the products sold by weight. You cannot use just any weighing device but instead a Legal For Trade Scale that is NTEP Approved. Many states have different requirements for the sensitivity of the scale and whether they accept displayed scale division (d) or they only accept the verification scale division (e). Always check with your State Department of Agriculture Weights & Measurements Inspector current requirements to be in compliance for selling marijuana.
